3 ways to sharpen a knife from a meat grinder at home

Basic information

Consider some information and features of the meat grinder cutting tools:

• The cutting quality of various types of products is largely independent of the sharpness of the cutting edge. Ideal flatness of the working surface is the key to the quality of cutting products. Therefore, this is the main goal during sharpening.
• Sharpening at home is done only with an abrasive material that has fine fractions. This material allows you to maintain a tight fit between the two types of knife.
• Sharpening should be manual, without the use of any additional electrical tools or apparatus. The main reason is that the steel can be overheated. This will lead to the fact that this cutting element will become unsuitable for further use. It only remains to throw it away. Sharpen by hand.
• During the procedure, the work surface should be abraded with the part that comes into contact with the disc after assembly of this kitchen device.
• Both types of device are processed.
• Before starting sharpening, the cutting components must be thoroughly rinsed and dried.

Using a drilling machine

The second method requires the use of special equipment - a drilling machine, a grinder and a knife holder. Use the fork drill bit to sharpen the mesh correctly.

Let's move on to the process of sharpening the knife correctly:
Place the carborundum circle on a hard surface and press the mesh firmly;
Press the drill against the circle and turn it on;
Important - keep the device upright;
For the correct sharpening of the knife, use an attachment that is similar in shape to a pin with a square section;
Put a knife on such a rod and turn on the drill.

Once the knife is sufficiently sharpened, then we can assume that the work is complete and you can clean up all the equipment used.

And in order to determine that the knife is sharpened correctly - look on the Internet for photos of the correct sharpening. This will help you compare your work with others and check the outcome.

Grinder and grinding wheel

When using a grinder, be sure to follow the precautions and safety precautions. Pre-lubricate the blade with sunflower oil and put on gloves

To work, put the cutting part on the pin and secure, then sharpen the blade with a grinder at a right angle.

And so that the knife does not overheat, periodically take breaks. To increase the efficiency and safety of the procedure, you can use additional Velcro attachments for the grinder.

Dexterity and experience are required when using an abrasive disc or grinding wheel, as well as safety precautions. Before the procedure, wear protective gloves, remove cutting objects and lubricate with sunflower oil. Then start the circle and press the blade against the rotating disc. Take breaks periodically to cool down the metal.

The principle of operation of the elements

Meat grinder spare parts assembly diagram

To sharpen a grinder knife at home, you need to know how they do their job. If you look at the device from the top, namely the tray where the meat is placed, then you will be able to notice the auger. It rotates thanks to the handle of this kitchen tool (if mechanical control) or an electric motor. This brings the meat pieces to the cutting edges of the machine.

Many may not know, but this tool has two cutting elements.The first is a knife in the form of a grid, which has holes and is stationary, the other is a four-blade knife that rotates. The process consists of two stages:

First, a movable four-blade tool crushes the meat pieces.

Four-band cutting element

They are then pushed through the mesh knife.

Mesh protecting the knife

The very procedure for chopping pieces of meat should not be inconvenient. This is achieved by correctly positioning the cutting tools and sharpening them. The first sign that the cutting elements are becoming blunt is an increase in your efforts as you twist the product. Simply put, if the procedure goes with some inconvenience, they should be sharpened.

There is a second sign that the cutting tools need sharpening. It can be found when cleaning a meat grinder. If the meat fibers get stuck between the two knives, this means that they are not tight. They just need to be corrected.

Fixed Grille Sharpening Secrets

The mesh knife is more difficult to handle:

• the inner cavity of each hole is inaccessible for processing, and it is the second side of the corner forming the cutting edge;
• the contact surface with the movable knife is large;
• the requirements for the accuracy of the processing of the plane are high.

What you need to know about the stone

For processing, it is best to use a new abrasive material with a fine grain and a perfectly flat surface. It is checked with the side of a metal ruler against the light, applying it to the working plane of the stone in various positions. So any irregularities will be clearly visible. You cannot work with a defective stone.

The working area of ​​the abrasive material on each side should be at least twice the diameter of the circle of the mesh knife.

Technology tricks

The grate must be evenly pressed against the surface of the abrasive material. To do this, three fingers are placed on it at once.

They create the same pressure of the treated surface against the abrasive. The grille is driven with small turns in the horizontal plane, slightly rotating around the axis. In this case, the metal is removed evenly.

Features of wetting with water

The bar and grate must be moistened: an abrasive paste is created from the spent particles.

At the beginning of processing, when an extra layer of metal with a disturbed geometry is removed, this paste speeds up the processing process.

However, at the end of the process, this abrasive paste must be washed off often: it, penetrating into the holes of the grating, destroys the vertical wall, bends the angle of the cutting edge.

Working with a bar

The sharpening process must be controlled by the accumulation of sawdust on the stone and traces of abrasive material near the knife: scratches on the metal should be distributed randomly.

The technology is the same, but additionally they control the even state of the sandpaper surface.

A bar complete with a meat grinder and a homemade bar

Modern kits already contain a special sharpening block that is optimal for the type of metal of the meat grinder knives. This method is available to both men and fragile women. Before the procedure, read the instructions for the device and follow the instructions.

As a rule, a sharpening block is worn instead of a disc with holes and the meat grinder is rotated as usual. In this case, you need to turn the handle evenly, slowly increasing the speed. For sharpening the disc, a second bar is provided, which is put on instead of a cruciform knife and then the handle is started to rotate. If traces start to appear on the block, then the disc is already sufficiently sharpened.

You can make a whetstone yourself. This is the easiest and most affordable sharpening method, however, it is only suitable for knives that are slightly dull. A very dull blade will not save you. For the procedure, take a fine-grained sandpaper and wrap a piece of wood or other hard and even object.

It is important that the block has a level and firm surface! Wrap the block with sandpaper and secure it securely so that the structure does not disintegrate in the process

Gently start rubbing the blade over the surface of the sandpaper. Continue the procedure until you get the desired result

Continue the procedure until you get the desired result.

How easy it is to sharpen a movable knife

The cutting edge of each blade is formed by the angle of intersection of the plane of contact with the grating and the side.

Its value> 70 ÷ 80 degrees is formed by the plant. When sharpening at home, it is recommended to keep the exposed size. Therefore, the approach angle is restored by sharpening in two planes.

How to securely straighten the side of a meat grinder knife

This side can be corrected in all the same ways as with an ordinary knife. The most popular home treatment for:

• emery wheel;
• bar;
• grindstone.

Emery wheel

The position of the knife is shown in the photo.

However, here you can clearly see two mistakes that beginners often make:

1. Coarse grain size of the stone;
2. Worn side surface of the emery wheel.

They must not be allowed: the knife will be ruined.

Sharpening on a bar

Each knife blade from the side is alternately processed on a sharpening bar.

It should be fixed strictly in the plane of the factory corner. If the knife deflects due to a loose fit, then there will be no good result.

Sharpening on ceramics

Homemade sharpening stones are not difficult to make at home from ceramics. Of course, they are inferior in quality to a professional set of tools, but they allow you to perform everyday tasks well.

Metal sawdust will begin to settle on the sharpening stone. They must be washed off periodically with water.

How to fix a knife in the main plane

At home, two methods are most available:

1. Sharpening bars, stones, ceramics with a fixed sharpening plane;
2. Fine-grained sandpaper - zero grade.

Sharpening on ceramics

The knife is placed with its main plane on a hard abrasive material. Press it with your fingers in the middle part, ensuring an even fit of the surfaces, and rub in in a circular motion.

The sawdust formed on the stone should be washed off.

Sharpening on sandpaper

This technology repeats work on hard abrasive material. However, sandpaper is easily deformed and wrinkled. Its curves work non-uniformly on the metal.

Therefore, sandpaper is placed on a hard surface (steel plate, thick glass), fixing in various ways. You can just wrap a wooden block around it.

How to control the quality of sharpening

The surface to be treated should be visually inspected periodically in bright light.

It will allow you to clearly see the process of removing oxides, burrs, removing cracks and dents. The work is carried out until the surface of all four blades is completely leveled.

Sharpening methods

You can sharpen a knife from a meat grinder:

• a sharpening stone;
• on the machine;
• sandpaper.

Abrasive stone

Sharpening stones are natural or artificial stone blocks. Advantages:

• low cost of material;
• the possibility of step-by-step quality control of sharpening.

Disadvantages:

• low processing speed;
• when using low-quality stones with heterogeneous grains, damage to the sharpened plane is possible;
• a set of stones with different roughness is needed.

You can sharpen knives for a meat grinder with a sharpener as follows:

1. A stone with a roughness of 40-60 microns is taken and fixed on the table.
2. The stone is lubricated with oil.
3. A knife is taken, applied to the stone with the entire working plane.
4. Sharpening is carried out - the cutting edge moves along the abrasive bar in a rotary-circular motion.
5. Chip flushing is periodically performed, then relubricated and turning again.
6. Similar operations are performed with a metal mesh.

Grinder

The sharpening machine allows you to fix the abrasive wheel and cutting blades at the desired angles, sharpen the edges quickly and safely, and perform a large amount of work with high productivity. To prevent overheating of the steel, the engine speed is regulated.

When using machines, it must be borne in mind that they have a number of disadvantages:

• the complexity of the control of the turning process;
• high cost of equipment.

Electric sharpening of a knife from a meat grinder:

1. A disc with a suitable roughness is fixed to the machine.
2. GOI No. 4 paste is applied to the grinding wheel. The time required for the paste to dry is waiting.
3. The power to the machine is turned on. The speed is selected at which safe turning can be performed without overheating of the steel. The sharpening angle is set in the range of 70-80 degrees.
4. Cutting edges on the abrasive surface are moved in a circular motion until the desired level of sharpening is achieved and a smooth, shiny edge is obtained.
5. When turning for more than 5 minutes, you need to let the machine run for a few minutes at idle so that the metal has time to cool down.
6. The surface of the mesh is cleaned in the same way until a flat plane is obtained.

Emery cloth

Disadvantages of sandpaper:

• when turning, it is difficult to fix the blade and protect it from bends, waves;
• work must be carried out on a flat, solid surface;
• low processing speed.

Sharpening knives with sandpaper:

1. Prepare a flat and solid surface of the table, cleaning it from dirt and debris.
2. Spread out and level the canvas on the table. It should be fixed along the perimeter so that it cannot move or wrinkle during processing.
3. Lubricate the cutting edge and grind in a circular motion.

How you can sharpen meat grinder knives at home

There are several common sharpening methods using simple tools. Let's take a look at some of them.

On a grindstone

If this is your first time doing this, purchase a new corundum whetstone from the hardware store. Its diameter should be 180 mm, and the grain size should be from 40 to 60 microns.

1. Sharpening the knife must be done under water, so place the stone on a flat, hard surface with a stream of water, or moisten it abundantly from a suitable dish. The water will cool the metal and serve as a lubricant, reducing friction between the knife and the stone. Fix the stone to the surface.

Place the whetstone on a horizontal surface under running water

2. Take a knife, attach it with the blade to the stone and start to drive in a clockwise direction with even pressure.

Drive the blades of the knife along the sharpening stone clockwise

3. Do not forget to check from time to time how much the metal has been ground off and whether the sharpening of the knife's plane is even.

Control the quality of sharpening

4. When you finish sharpening the knife, carry out the same manipulations with the mesh: grind its surface that is adjacent to the knife in a circular motion.

Perform the same manipulations with the lattice knife.

5. Check the quality of the work in the same way: the surface of the mesh should be smooth and completely shiny.

If the grill is smooth and shiny, then the job is done correctly.

6. Now check the tightness of the knife against the net for the light. There should be no gaps.

Fold down knife and wire rack to check for gaps

7. If everything is done correctly, rinse the knife and mesh so that no abrasive remains on them, assemble the meat grinder and test it.

On a grinder

This method is very convenient and fast. The knife sharpening machine is equipped with a disc with a smooth abrasive surface. A paste containing the smallest particles of abrasive is applied to it before sharpening. The paste dries quickly, making the disc rough.

Special machine for sharpening knives

The mesh is sharpened quite simply by pressing its surface against the plane of the grindstone. With a movable knife, the situation is more complicated. It needs to be sharpened in two stages. In the first stage, each of the 4 cutting edges is pressed against the rotating wheel at an angle of 70-80 degrees. It is necessary to strictly observe the angle of inclination of the knife blades relative to the grinding disc. At the second stage, the 4 resulting burrs are grinded, similar to the work that was carried out with the mesh knife.

This method can be inconvenient for those new to sharpening meat grinder knives. It is difficult to immediately maintain the correct angle of inclination and comply with all safety rules.

On sandpaper

The third method is the simplest and most affordable. You probably have sandpaper in your home or in the garage, in extreme cases - in the store it costs less than a sharpening stone, and even more so - a machine.

Sharpening knives on sandpaper is the easiest and most affordable way

On a horizontally placed sheet of emery, rub the four-bladed knife alternately until sharp and shiny over the entire working surface. The movements should be circular, as if you were wiping a surface with paper. Process the mesh in the same way.

We sharpen the knife and grate with sandpaper

To do this, you need to purchase fine-grained sandpaper. The sharpening material is firmly fixed on a flat horizontal surface. After fixing, you can start the process of sharpening cutting knife elements - blades. You need to firmly press them against the surface of the abrasive and rotate them in a circle for several minutes. As a result, the knife should become shiny and pointed. The mesh disc is sharpened in a similar way. The whole procedure will take you no more than 10 minutes.

If the knife is too old or rusted, then in any case it will have to be pre-processed on a grinder. If there is no such tool in the house, then a construction drill can be an alternative option. You will also need a bolt with the same diameter as the knife hole. The bolt is inserted into the drill chuck, after which it is passed over the knife with a kind of tool. True, the work will turn out to be rough, so this method can only be used to remove rust from the knife surface.

A sharpening machine can not be seen in every home, therefore for sharpening meat grinder knives you can use any home method using a fine-grained abrasive. Regular maintenance of the cutting elements of the meat grinder will make the process of chopping food as pleasant as possible, which means that you will be able to pamper your household with delicious dishes much more often!

Meat grinder device

Before moving on to the process of sharpening a knife for a meat grinder, it will be useful to understand what the device itself is, what is inside it and how it works.

A meat grinder (a similar device used in industry is called a spinning top) is either a completely mechanical or electromechanical device that is used to grind meat and other types of food. Thus, the meat grinder will be useful not only for those who love homemade cutlets, but also for those who wish to make spaghetti, noodles and even cookies with their own hands. In addition, the device can also be used to extract juice from not too hard vegetables and fruits.

This useful device was invented in the 19th century by a certain baron named Karl Drez.

The device of the simplest manual meat grinder contains the following parts:

• body with meat receiver;
• lattice;
• knife;
• screw shaft;
• handle.

Principle of operation

The food product that needed to be processed with the help of a meat grinder first enters the conveyor of the auger, with the help of this conveyor it is pressed against the grate, and then it is cut with a knife that slides over the surface of the grate. The meat receiver, which is installed on the manual meat grinder, has ribs.With the help of these ribs, smaller pieces of meat are cut from those pieces that were too large to pass through the auger.

Unlike the same blender, the process of cutting the product inside the meat grinder occurs without interruption. That is, the food product is placed in the meat receptacle. He leaves through the bars.

In order to work with a manual meat grinder, it is necessary to constantly apply considerable efforts to its handle. For this reason, the device itself must be firmly fixed to some surface (usually attached to a table). For these purposes, hand-held devices are equipped with a clamp. For electrically driven devices, however, a clamp is not required, and they are created in a floor-standing or table-top design.

Household options for electric-driven meat grinders, as a rule, contain in their configuration a long and narrower neck of the meat receiver, as well as a pusher that prevents accidental fingers getting into the auger.

In order for the electric drive device to be more convenient to use in everyday life, you should cut the meat into small pieces before serving it into the receiver.

Knives and their main problem

Rotating knives may differ in appearance in different models and configurations of devices, however, the principle of their operation is absolutely the same. Today, the purchase of a knife for a device that chops meat is not difficult, and with a high probability you can find what you need in any specialized household store.

If you already have a knife and it's just dull, then what's the point of running to the store and spending money when you can just sharpen it. As usual, users of meat grinders find the problem of bluntness of the knife during the process of grinding meat itself. As a rule, at first everything goes like clockwork, and then suddenly the device starts to mince meat or other product, and the whole process gets out of control.

Why grinder knives need to be sharpened

Depending on the frequency of use of the meat grinder, its blades lose their sharpness. This can occur due to the formation of small chips and depressions in the place where the movable and stationary cutting elements come into contact.

Knives in a meat grinder must be sharpened at regular intervals.

Basically, the device works with a relatively soft product - meat. But small bones or tendons, when grinding, fall on the cutting edge of the blade, which leads to a gradual loss of sharpness. At the initial stage, you can find that the meat grinder began to "chew" the meat, and soon after that it completely ceases to grind it.

Also, with improper care, the metal from which the knives are made begins to oxidize and rust. It also negatively affects their severity.

Today, manufacturers produce all the components for small household appliances in sufficient quantities. You can easily buy a new sharp knife for a meat grinder, especially an electric one. But this will require additional costs, in addition, often the problem is revealed at the moment when the cooking process has already begun.

Cutting elements for electric and mechanical grinders have approximately the same shape and metal alloy composition. The only difference is that in a mechanical device the knives are rotated manually, while in automated devices there is a built-in motor that performs a similar function. Therefore, you can sharpen the blades in the same ways.

How to understand that knives from a meat grinder need to be sharpened

Before taking measures for sharpening meat grinder knives at home, you need to understand the device of the "food processor" and the principle of its operation. If you look into the meat grinder from above and carefully look at the meat feed tray, you can see a spiral roller, which in professional language is called a screw. It is driven by a crank or an electric motor.His task is to get the meat cut into pieces and move it to the knives, giving a kind of push-stop.

The knives are represented by a fixed mesh structure and a moving element with four blades. The mass moving along the auger is crushed with sharply sharpened knife blades, after which it goes to the mesh knife.

When preparing minced meat, you need to understand that the process of twisting products should not cause difficulties. Meat or other products should pass without problems, without getting stuck anywhere. The fact that the knives need to be sharpened is evidenced by the deterioration of the work process, when each time you have to make more efforts to scroll the handle. The second sign is the stuck meat fibers between the knives.

Using a whetstone

This method is suitable for those who have no experience in sharpening meat grinder knives. To get started, buy a corundum whetstone from the store.

It is recommended to purchase a model with a diameter of approximately 180 mm and a grain size of 40 to 60 microns. As soon as you have purchased such equipment, you can proceed to the very process of sharpening the knife:

To get started, place a stone in a sink and moisten it liberally. This is necessary so that the water acts as a lubricant and cooling of the metal. Then fix the whetstone itself. You can use a rag for this - place it under the whetstone.

Take the cutter and place it with the blade against the stone. Next, perform circular movements clockwise with equal pressure on the knife itself. Continue sharpening until the surface of the element is shiny.

Upon completion of sharpening, make sure that the fit is tight. To do this, it is worth putting them together and looking at the light. No gaps should be visible. To finish work, rinse the knives under running warm water. This is done in order to wash off the abrasive.

That's all, after you finish sharpening the knife, try the meat grinder at work.

How a meat grinder works: in simple words

When the handle is turned, the auger shaft pushes the meat forward. It fills in the holes of the grate and is cut off by four blades of a movable knife.

High-quality chopping of meat occurs when the four-blade knife is firmly pressed against the grate: both of these elements work to cut the fibers, like the blades of scissors.

Clarity of the knives fit and the elimination of a gap between them ensure:

1. a washer mounted on the auger shank;
2. clamping round nut for securing the shaft.

If the thickness of the washer and the thread of the nut are not enough, then a gap will arise between the movable knife and the grate, which will not allow high-quality chopping of meat.

Blunt edges of the knife and gouges on the grill plate greatly impair the quality of the meat grinder.

How you can sharpen meat grinder knives at home

Regardless of which method you choose, you need to prepare first. This will give you the opportunity to sharpen with maximum speed and quality, without damaging parts.

As a rule, the entire process of returning sharpness to knives at home takes about half an hour. You can use a grindstone, grinder, abrasive discs, or sandpaper. You don't need special skills to do this. And you won't need to spend a lot of money on additional devices.

Let us now figure out in more detail how to properly sharpen a meat grinder knife at home, and what kind of knife is used to sharpen the grate.

On a grindstone

It is very easy to sharpen meat grinder knives with a corundum sharpening stone, which is on the shelves of any specialty store, without having any experience.

The process should take place under a small stream of water. Place the stone in the sink and wet it well. Water is needed to lubricate and cool the metal. Fix the whetstone. You can do this with a rag.Take the cutting element, place it with the blade against the stone and start sharpening in a circular clockwise motion. While doing this, press down evenly on the entire cutter. It is necessary to sharpen until the surface of the cutting element begins to shine.

Do the same with the mesh. Once you're done, check to see if the two pieces fit snugly together. To do this, just put them together and look at the skylight. Make sure there are no gaps between them.

If you are going to sharpen very blunt cutters, then try doing it in a different way, which is a little more difficult, but more effective. Put on gloves, secure the cutting element, or simply take it in your hand, press the stone against the knife and rub it in a circle. This must be repeated several times.

On a grinder

You can also sharpen all parts by hand using a sharpening machine. But if you don't have one at home, don't buy it on purpose, it's better to just try a different method. The fact is that it is not so easy to work with him. And you can just buy it, and then you will not be able to work with it, and it will stand.

Buy a rotating sharpening disc. Apply goyi abrasive paste to it. It will dry out and, with the help of small particles in its composition, will create a roughness on it.
Take paste number 4 with a grain size of 17-8 microns.
Then turn on the unit and gently press the mesh against the moving element

It is important to do this with evenly distributed force throughout the object.
If you are inexperienced in this, you may have problems sharpening a four-blade cutter. Sharpen it in several stages.
First, sharpen each part of the part individually, pressing it at an 80-degree angle.

The most important thing is to keep this corner.
And then grind off the resulting burrs. This should be done the way you downloaded the mesh. Be sure to let the spare parts rest so that it cools down.

This is a great method for sharpening any part, such as a Bosch meat grinder knife. Although in this case it will have to be done much less often. After the end of the process, disassemble the unit and clean it.

On sandpaper

Sharpening meat grinder knives with sandpaper is the easiest method that everyone can afford. At least a few of its sheets are sure to be found in any kitchen. And even if not, then it will definitely be found in any specialty store. And this paper is much cheaper than all of the above devices.

Take a leaf, place it in the place where you will sharpen the part. Fix it with accessories if necessary. Rub the knife by turning it in a circle until it starts to shine and becomes sharp. Sharpen the net in the same way.

Sharpening with abrasive discs

You can sharpen meat grinder knives using two abrasive discs. Sometimes they are even added to the meat grinder set upon purchase. They should be applied like this:

1. Replace one of the knives with a disc in the device.
2. Start rotating the meat grinder slowly. This will sharpen the knife that remains in the device.

Use the same principle to process the second cutting element. Do not overdo it and do not make more than 90 revolutions.

3 ways to sharpen meat grinder knives at home

Regardless of which method you choose for sharpening, you need to prepare the necessary materials with which the work will be done. The correct organization of the process will allow you to sharpen knives quickly, efficiently and not damage them. You can return the blades to their previous sharpness yourself, having at home one of the sharpening tools and about 30 minutes of time.

There are several ways to sharpen meat grinder knives:

• on a grinding machine;
• using a grindstone;
• sandpaper.

All these methods do not require special skills and expensive devices. You can purchase everything you need at hardware stores.

On a grindstone

If you have absolutely no experience in sharpening meat grinder knives, buy a corundum whetstone from a specialized store. The best option would be if its diameter is about 180 mm, and the grain size is from 40 to 60 microns.

Sharpening stone - a simple and affordable tool for sharpening knives

The process itself has the following features:

1. Sharpening should be done under a weak stream of water. To do this, place a stone in a sink and moisten it liberally. The water will act as a lubricant and cool the metal.
2. Secure the whetstone to the work surface. To do this, you can put a rag under it.
3. Take the cutter and place it with the blade against the stone.
4. Perform circular movements clockwise with even pressure on the knife.
5. Continue sharpening until the surface of the element is completely shiny.
6. After the sharpening of the rotating knife is finished, do the same with the mesh knife. To do this, place it on the stone with the side adjacent to the first knife.
7. After sharpening both knives, check the fit. To do this, fold them together with their respective sides and look at the gap. No gaps should be visible.
8. Finally, rinse the knives under warm running water to rinse off the abrasive.
9. Assemble the meat grinder and try it out.

On the machine

This is a very simple and quick way to sharpen your knives yourself. Sharpening is done using a rotating grinding disc. Before starting work, an abrasive goi paste is applied to its surface, which, when dried, creates a rough surface on the disc due to the content of small particles in its composition.

A little skill is required to work on a grinding machine.

Sharpening of the mesh knife on the machine is carried out as follows:

1. Apply abrasive paste to the surface of the easel wheel and wait until it dries. Only then will the device be ready for use.
2. Switch on the machine. The disc will start spinning.
3. Gently press the mesh knife against the surface of the disc. Try to distribute the pressure evenly.

Sharpening the cutter with a machine can be difficult if you have no experience with the machine. It must be carried out in 2 stages:

1. First sharpen each of the 4 knife blades by leaning them against the rotating blade at an 80 ° angle.
2. The second step will be to grind off the resulting burrs. To do this, carry out actions similar to sharpening a mesh knife.

Sandpaper

One of the easiest and most affordable ways is to use sandpaper. She will certainly be found in your home. As a last resort, you can buy it at a hardware store or hardware store. The cost of this tool is several times less than the cost of a grindstone or machine.

Do not use paper with a coarse grain fraction to sharpen the knives of the meat grinder.

So, the sharpening process is carried out in the following sequence:

1. Place a sheet of sandpaper horizontally on the worktable. For convenience, it is desirable to provide him with additional fixation.
2. In a clockwise circular motion, rub the knife until you achieve the shine and sharpness of the blades.
3. Do the same with the mesh.
