Orbital sanders: features and tips for choosing

Rating of the best models

Hand tools that cut wood pieces work by removing a small layer of wood using the motion of an abrasive tool. Design features make it possible to divide grinding machines into several types.

Household

The advantages of the device include power, the ability to process oak, beech, larch, the presence of a dust collector and a sturdy body. The disadvantages can be considered ill-conceived balancing, the complexity of vertical work.

Device and principle of operation

In terms of the set of accessories and their device, all grinders are similar to each other. As a rule, they consist of several elements.

• Frame. Most of the time it is made of plastic, but don't let that confuse you. In production, specially developed polymers are used, which are distinguished by high indicators of wear resistance and strength, but at the same time they are light. These qualities make them ideal for making all body parts, from the power on / off button to handles.
• Lever. Each grinder needs to be held in a certain position somehow. For this, the handle serves. It is distinguished by an ergonomic shape, and it must also have a thread, so that even a heavy machine is comfortable to hold. The important point is that the handle "dampens" vibrations from the grinder, so that with its help it will be possible to direct the machine as needed, while not giving all the strength to hold it.
• Electric motor. All but the oldest grinders use an electric motor. It can be powered from various sources: directly from the electrical network or from a battery. Electric grinders are more convenient. They have good performance due to the fact that they are powered from the mains and do not require constant recharging. Roughly speaking, they work for themselves and work until they overheat. Cordless sanders are another matter. They cannot work for too long and are mainly used when working with hard-to-reach places, when it is not possible to connect the machine to an outlet.
• Compressor motor. This is just an exceptional case when the motor does not run on electricity. The operation of the engine is carried out by supplying compressed air, which drives the mechanisms.
• Reducer. Helps convert the energy produced by the motor into useful work. It is necessary in order to increase the torque and speed of the device, while reducing the load on the motor. It can give the ability to switch from 1 to 5 speeds.
• Spindle. This part serves to impart a rotational movement to the nozzle. One of its ends is a threaded shaft to which the attachment is attached, and the other is attached to the grinder itself. The spindle can be attached both parallel to the device body and perpendicular to it.
• Protective cover. Protects the master from sparks, bouncing particles and small debris that inevitably forms as a result of working with a grinder. If such small particles bounce off the work surface, they can cause serious injury to a person, for example, if metal shavings enter the eyes.

The principle of operation for each machine is different. It depends on what type your device belongs to. Basically, all machines grind and polish the surface due to the frictional force, however, the desired effect is achieved in different ways.

Rating of the best devices

For uninitiated people or novice specialists, you can deepen the topic a little and offer an overview of several popular models of brush grinders that have proven themselves in work on the positive side:

• Makita 9741;
• Interskol SHM 110 / 1400EM;
• Sturm AG1014P.

Makita 9741

The Makita 9741 Brush Grinder is a tool for professional use under heavy loads. The main purpose of the machine is to grind surfaces, to clean surfaces from oxides, rust and paint, to show the structure of wood materials, to participate in the polishing of products.

Interskol PShM-32/130

Compact tool PShM-32/130 with a delta-shaped sole for fine grinding at corner joints and on a relief surface (a panel door made of solid wood, for example). Access to any corner is provided by the tapered sole. The combination of the minimum amplitude and low vibration frequency of the platform guarantees professional quality:

• when removing single-layer coatings (consumables with large grain are needed);
• when grinding smooth gradients (fine sandpaper will be required);
• when dry polishing protective layers of paints and varnishes (with a suitable soft tip).

The connection of the consumable with the sole is carried out using the Velcro system (also known as Velcro), which reliably holds the abrasive sheet during operation. In the absence of the necessary consumables, they can be cut out of sandpaper with a felt layer. For the full-fledged operation of the built-in dust removal system, holes must be made in the self-cut sheets according to the pattern of the sole. The main thing is not to subject this amateur tool to constant intense loads, and to blow all openings with compressed air at the end of the work.
