Grinding machines makita: features, models and operating rules

Fixtures and spare parts

Regardless of the specific model of the polishing machine, its auxiliary equipment plays an important role. Among the nozzles, the bag stands out for its role. It allows you to collect as much debris, dust and waste as possible. As a result, the work is done as cleanly as possible.

Adhesive backing pads allow the sanding discs to be attached to the holders. Special flexible shafts help to work in hard-to-reach places. For the grinding itself, brushes or rollers made of nylon, metal and special composites are used. Polishers are supplied with main and auxiliary handles. But when choosing such components, you must carefully check so that they facilitate the work, and do not complicate it.

The sole for a vibration machine, as already mentioned, can be made in the form of a triangle or rectangle. The first type manifests itself better in a confined space, the second - in cases where it is necessary to process the maximum area. If the initial power cord is short, you will have to use an extension cord continuously. Of course, all spare parts and auxiliary components must be purchased only from official manufacturers.

Peculiarities

At the time of making a purchase, experts advise paying attention to such parameters as:

• power;
• dimensions and weight;
• disc diameter.

Sanders of this type are considered hobbyists because they are not designed for complex tasks. But even among them there is a classification by functionality. If the tool is used often, then it is better to choose a machine that demonstrates great performance.

A tool with low power cannot be used for a long time, so it will need to be given a break. Weak power can range from 400 to 800 watts. Professional equipment never demonstrates such indicators, and mini-cars just fit in.

Models differ in their low weight. It depends on the manufacturer what the mass of the finished unit is. If the instrument is used by a person with good physical fitness, then it may be heavier than if purchased for use by a teenager or a woman.

The cost of a household polishing machine ranges from 2 to 5 thousand rubles. Domestic tools are slightly cheaper than imported ones, but this does not mean that they are inferior in quality or reliability. Domestic manufacturers do not increase the cost of their products, and it is quite easy to find spare parts for such units. Regarding maintainability, the price of some polishing machines is such that it is easier to replace the tool than to repair it, especially for a Chinese or Korean product.

For how to make a mini sander with your own hands, see the next video.

UPM-180 / 1300EM

Initially, the Interskol UPM-180 / 1300EM polishing machine was designed to work with metal and wood. However, as practice has shown, it works great with other materials, including polymers and painted surfaces.

As for the technical characteristics, the engine power is 1300 watts. For a hand-held apparatus, this is more than enough. This power allows you to control the device well, while the performance will be at its best. Among other things, there is a speed control function. Depending on the material to be processed, you can select the required number of them so as not to damage the surface. The function of maintaining the speed is also provided.

Angle polishing machine UPM-180 / 1300EM can be connected to a regular socket: power supply parameters - 220 V with a possible deviation of 10%. The machine itself weighs 3.2 kg, which allows you to work with it for a long time. The tool is not too heavy, perfect for manual work.

The advantages of UPM-180 / 1300EM include:

• powerful engine for high performance;
• comfortable handle with soft pads;
• the function of maintaining the speed;
• built-in soft start system;
• the ability to attach sanding sheets with Velcro.

There are also disadvantages:

• the expected service life of the tool is only 3 years;
• no overheating protection;
• there is no protection against repeated switching on;
• no loop protection.

Reviews about the tool are purely positive. Masters note the convenience of working with the machine. According to their assurances, she copes well with the polishing procedure. The affordable price of the device is separately noted in comparison with the models of other firms on the market.

Polishing machine prices

As noted above, the cost of a polishing machine directly depends on its class, weight, manufacturer and power. On average, among the household class, the standard price ranges from 2,000 to 7,000 rubles. Professional polishing machines will cost the buyer from 6,000 to 30,000 rubles.

The most affordable option is the DIOLD MP-0.42 10044020 model with a disc diameter of 125 mm, a power of 420 W and a weight of 2.1 kg. The most expensive polishing machine is the RUPES LH22EN with a disc size of 200 mm, a power of 1020 W and a weight of 3.3 kg.

It is also always possible to purchase a used tool of higher power at a low price.

However, in this case, attention should be paid to all mechanisms so that after a couple of days the machine does not deteriorate.

Grinding Equipment Selection Criteria

Before starting to clarify the details of the characteristics, you should decide on the purpose of using the tool. If the auto polishing machine is not planned for frequent use, there is no point in overpaying for the brand and additional features. Keep in mind that machines with a minimum set of operating modes have a long warranty.

It is not difficult to make an overview of polishing machines when determining these key parameters:

• product weight;
• installed capacity;
• rotation speed and speed control;
• resource or warranty;
• price segment;
• characteristics.

It is worth considering the direction of use of the power tool. Some models have a wide range of applications, for example, they work with polishing metal, plastic or rubber. The possibility of installing a wide range of nozzles is also taken into account.

Rotation frequency of the nozzle

For a tool powered by a stationary network, the indicator ranges from 1 to 3 thousand revolutions per minute. We immediately reject the battery models as not capable of maintaining the same speed for a long time. The only reason a 12-volt car polisher will be used is the inaccessibility of electrical networks. However, the battery will need to be recharged regularly. Another feature is the relatively high weight. For example, the popular Ferm FCP-180K cordless car has a mass of 5.2 kg due to a capacious battery.

A professional auto sander should ensure smooth running. This function is expressed in maintaining a stable speed regardless of the degree of pressing the rotating circle to the surface. The parameter is provided by an electronic unit for maintaining constant values.

The relationship between the installed power and mass of the model

Mass models are offered in the power range from 400 watts to 1.5 kW. A powerful model will take less time to complete the entire range of work. At the same time, due to a more robust electric motor and large components, the entire model becomes heavier. With long-term work, not every worker can withstand the tension in his hands.But it is worth remembering that if you need to perform precise work on a small surface, an oversized polishing machine for a car is better suited. Therefore, the line of machines is represented by different models. In the hands of professionals, a tool is used, taking into account the type of work.

Mass semi-professional models have a constructive weight of 1 to 2.5 kg. Only a professional car polishing machine for a car will exceed the value of 4 kg, but it should not be purchased for one-time use.

With an increase in mass, attention is paid to the convenience of holding the tool in hands, which is associated with the type and class of the machine. For a powerful tool, a prerequisite is the presence of two points of retention

Tool class and resource

Depending on the direction of application of the equipment, manufacturers are ready to offer three categories that the polishing machine will correspond to:

1. Household tool. The duration of continuous operation will not exceed 30 minutes, and the resource is limited by a warranty from 3 months to a year.
2. The semi-professional models will provide the stated performance for the full scope of work. The resource of any model will depend on the operating conditions and will be at least 3 years.
3. Professional models are ready to work for a long time while maintaining all the characteristics of work, taking into account the equipping of the working mechanism with a cooling system for electrical and mechanical equipment. The resource is limited only by the conditions of maintenance.

Before deciding on the class of a car for polishing a car body, it is worth considering certain advantages of various models, depending on the type of working body.

Varieties of polishing machines

When choosing a tool, the peculiarities inherent in the species must be taken into account, taking into account the design:

1. Tape tool. The type is characterized by high productivity, but is suitable only for processing large areas without a complex profile.
2. Surface grinders. Good performance is achieved due to the high vibration frequency of the rectangular sole. Vibration occurs with a small amplitude - up to 2 mm.
3. Orbital instrument. The working body not only performs a rotational action, but also oscillates due to the eccentric, providing high quality work.
4. A delta sander or angle polisher works on the basis of vibration. The limitation in use is associated with low productivity and the possibility of using it for processing hard-to-reach places.

For an overview of the Makita belt sander, see the video below.

Advantages and disadvantages

Like any other sophisticated tool, the Makita polisher has its pros and cons. The main advantages include the following characteristics:

• wide range of models;
• affordable price;
• complete safety during operation both for a person and for a processed object;
• the presence of a number of professional instrument settings;
• long service life;
• the ability to perform work quickly and efficiently.

In addition, the manufacturer adds to some models as additional compensation some accessories for storing and transporting the polishing machine.

There are also some disadvantages to such a tool. The main one is the medium power engine. In addition, professional reviews indicate that models of the Chinese assembly, with prolonged work, begin to vibrate in their hands. And although this fact does not affect the very result of polishing, it is still unpleasant.

Correct use of the tool

It is very easy to maintain cars of a famous Japanese company. Such devices are very reliable in operation. They are distinguished by their great performance. During work, you must follow the simplest operating rules.

Installation of the side cover on the machine is carried out in the following order:

• There is a slot on the cylindrical part of the gearbox. A tool clamp must be installed near it.
• Turn the cover.
• Fix the cover with the screw.
• Slide the shaft onto the inner flange.
• Lock the lock nut while pressing the latch.

To install the tape, you do not need to study the design of the device. For this, the lever is pulled back and the sanding strip is positioned from the outside. Then the lever is returned to its place. It is imperative to check that the belt is installed in accordance with the direction of rotation that is intended for it.

Model 9404 kit includes a dedicated dust bag. To install it, you need to place it very deeply into the fitting. The device must be cleaned regularly. It shouldn't have turned out to be full

This precaution will extend the life of the device.

Tape machine "Makita 9404" scrolls at idle on completion of work. This removes all dust from the instrument. If this is not done, the machine will quickly fail. In general, the products of the Japanese company have a rather long service life. However, the original parts should be used.

The belt and dust bag are as easy to install on this model as on previous models. Before work, the serviceability of the "Start" button is checked. The tool must speed up before machining the part. If this is not done, the device may be damaged.
