Features of vibration grinders

Used as an alternative to manual labor, the vibrating sander is a tool with a flat work platform on which special consumables are attached to perform surface cleaning and smoothing operations. Affordable cost, functionality and reliability make it an excellent choice for the home workshop. The technical features of flat grinders for wood allow them to successfully cope with large volumes of work, providing high quality surface treatment of the material without significant investment of time.

A vibratory sander is a device with an electric motor and a working flat sole, on which abrasive consumables are fixed with Velcro or special clips. By varying the grit size of the sanding paper used, you can make a rough or fine sanding, providing a continuous impact on the surface area selected by the expert. The amplitude of the platform movement is low, but the high frequency of movements allows achieving a higher quality of work performance than with manual grinding. Compact dimensions do not negate the functionality of the tool. The vibration type grinder has the following performance characteristics:

• light weight - most of the models on sale have a mass of 1.5 to 2 kg, the most powerful options reach 3 kg;

• engine power ranges from 110 to 600 W; most of the popular models are limited to 350-400 W;

• rotation speed of the drive shaft up to 25,000 rpm, directly affects the amount of vibration produced by the sole;

• the displacement in the horizontal plane depends on how rough the work is to be done; for the most delicate work, it is recommended to use grinders with an amplitude of 1.5–2.5 mm; for coarser processing, it is better to choose machines with a maximum displacement of up to 5 mm.

The vibration surface grinding machine is used in the workshop or during repairs, restoration of surfaces. The movable platform, in the course of its work, contacts the material, removing the top layer from it. The tool grinds materials with different indicators of hardness and strength. Artificial and natural stones, polymers, wood, metal are susceptible to action, ensuring the removal of plaque, impurities (carbon deposits, rust, scale). On the farm, the use of vibration PSHM is quite diverse.

With their help, you can perform the following actions:

• to achieve the desired evenness and smoothness of the wooden surface during the restoration and repair of furniture;

• renovate floors that have partially peeled off;

• clean household utensils used in cooking from soot;

• prepare walls, ceilings, window sills, stairs for decoration.

This is just a small part of the work that modern grinding tools successfully cope with.

The vibrating flat sander is designed for use in combination with various materials.For woodworking, models with a maximum platform size and a large power reserve are selected. They even make it possible to successfully work on corners of floors and walls. Mini-versions are convenient for use in hard-to-reach places, have a compact platform and low power. For work on metal, PShM is used in auto repair shops, as well as in the production of doors, fence structures.

With the help of the equipment, you can remove old paintwork, remove scratches, traces of corrosion and oxidation. The triangular or deltoid sole is indispensable for the restoration of old furniture and interior items. With its help, it is convenient to clean window frames and door frames from paint. Models with additional equipment can work with a round nozzle, replace eccentric counterparts.

On the market of vibration surface grinders, there are mainly equipment of European and American brands, as well as goods from China. It is worth taking a closer look at the rating of manufacturers.

• Bosch. This brand specializes in the production of electrical PCHM for carpentry professionals. The range includes models with a platform size up to 92x182 mm, developing up to 22,000 rpm at a power of 300 watts. The easily removable equipment is complemented here by maximum convenience when performing fine sanding of wood and plastic.

• DeWalt. It is an American brand specializing in the production of professional surface grinders. The models are adapted for continuous operation, including in the conditions of a construction site or large premises. They help to achieve the perfect smoothness of the coating without difficulty.

• Makita. This Japanese manufacturer presents a wide range of products, provides the most comfortable choice of PSHM for various purposes. The machines are equipped with modern control systems, powerful revving motors, dust extractors. The set of equipment is one of the richest.

• Metabo. This German brand mainly specializes in the production of eccentric models, but it also has surface grinding equipment in its range. Ergonomic body, compact dimensions and adjustable intensity of exposure make it the best choice for amateurs and professionals.

• Ryobi. It is a Japanese manufacturer focused on innovation. The machines have a special non-slip coating for the handle, and a fundamentally new dust removal system is used.

• "Fiolent". This is a rather interesting manufacturer that has recently received a Russian "registration". In its lineup there are heavy and powerful machines for scraping floors and other works that require long-term continuous exposure to the material surface. The platform has a large power reserve, while there is no unnecessary vibration.

• Interskol. This is a manufacturer that manufactures its products in Russia and for the domestic market. The range of models includes technologically interesting solutions with built-in dust extractors, vibration and noise damping elements. The massive vibratory sanders are equipped with pads or die-cast aluminum for maximum durability. The set includes a power button lock, indispensable for long-term continuous operation of the device.

It is worth considering how a vibratory surface grinder differs from eccentric and belt models. It is considered a more versatile option, allowing you to vary the level of surface finish.The belt sander is convenient for handling objects with a uniform texture, suitable for rough finishing. The surface grinding option allows you to achieve results regardless of the initial smoothness of the coating.

Eccentric models have their own characteristics. They are designed primarily for work on large surface areas and allow successful finishing. The eccentric sander is suitable for working on parquet floors. But it will not help in working with other, harder materials. Whereas the surface grinding unit will ensure successful processing even on the surface of fragile plastic or metal heavily corroded.

In fact, in terms of functionality, the vibratory PSHM is somewhere between the belt and eccentric models. With them, you can successfully complete the final processing of surfaces of various areas. Mini-versions successfully cope with narrow areas of material, difficult and hard-to-reach places. The adjustable rotational speed makes the PSHM as convenient as possible for working with surfaces with an inhomogeneous texture.

It is worth paying attention to when choosing vibratory surface grinders for several important criteria.

• Purpose of work. If the main task is to process large surfaces, it is worth choosing a model of a full-size range. For sanding hard-to-reach areas, it is better to use the mini-format options.

• Frequency and amplitude of the stroke. For rough processing, the most resourceful PSHM is suitable, which allows you to remove rather thick layers of material. If the model is purchased as a universal solution, you can choose the option with speed control, which allows you to adapt the model to the conditions of the task at hand.

• Feature of the lining. The base of the sole is made of alloys based on magnesium or aluminum, in budget models there are steel and polymer options. In a high-quality model, vibration at idle is almost not felt. It is better to choose a polymer overlay for the platform, which is less prone to wear and tear. The platform can be rectangular or deltoid, outwardly resembling an iron. Platform swivel is available on select versions.

• Method for attaching abrasive elements. Special equipment can be used, fixing the patch cut from sandpaper of the desired grain size on the surface. Spring-loaded clamps make the tool more profitable from an economic point of view. Velcro options will require sourcing of off-the-shelf rigs, increasing costs.

• Tightness. Fine dust that appears during the operation of equipment can negatively affect the operation of the electric motor. That is why all the parts of the body must be connected to each other as tightly as possible. Loose fit of elements at the points of attachment of bearings, channel system, switches will lead to the fact that the device will quickly fail.

• Weight. If you have to work on weight, a heavy and bulky device will be an inconvenient option. Optimal in this case is a compact model weighing 1.5–1.7 kg. The heaviest and most powerful models are suitable for combination with a workbench.

• Ergonomic A visually interesting model may turn out to be inconvenient to use due to the shape of the handle or the inconvenient location of the start button, power cord, difficulties with changing equipment. It is worth holding it in your hands before buying, trying it out at idle.

• The presence of a dust collector in the kit. In a closed room, its presence is the only salvation from the smallest dust particles scattering around. It is even better if a socket is available for connecting to a vacuum cleaner. In this case, all sawdust will be instantly removed, leaving the surrounding area clean.

Having carefully studied all the features and characteristics of vibration grinders, you can easily choose the best option for such equipment for personal use or a home workshop.
