Vibrating grinder: models, description, characteristics

Surface treatment with this equipment is provided by abrasive paper with a different grain size, which is placed on a rectangular sole producing reciprocating high-frequency motions. The grinding machine vibrating differs by gentle processing and at the same time high productivity, while it is possible to remove a layer of dirt and rust from the depressions, use for work with products that have a corrugated or uneven surface.

Use cases

The device can operate in several modes, each of which has a certain level of vibration. It is used for the final processing of plastic, metal, stone and wood billets. Grinding can be precise or rough, depending on the granularity of the sheets used. Vibrating grinding machines Also suitable for removing paintwork, rust and scratches.

Abrasives

The main working element is paper sheets with an abrasive surface, they are available in several variations and have different granularity. The most common are abrasive elements with medium-sized grains, smaller ones are used for polishing and fine processing. On the other side of the sheets there is a Velcro, which is necessary for reliable attachment to the sole of the tool and a quick replacement for abrasive elements of a different kind.

On many devices, you can use ordinary sandpaper, fixing with special clips. The main thing is to make holes on it to remove dust.

Processing of complex surfaces

Some vibrating grinders Allow you to work with products, some of the surface of which has complicated access. This is achieved by equipping in the form of a modernized sole executed in a triangular shape. It becomes indispensable when working with window frames and antiques. It is also convenient to use it on a small plane. It easily processes small grooves, grooves and faces. It is worth noting that instead of the sole can be installed a special grinding element, which allows to handle the smallest cavities and cracks. It has a standard locking mechanism, so when it is replaced, there is no need for special tools.

How to choose

On vibration grinders reviews should be studied in order to make it easier to determine the desired model. Most of the devices of the middle price segment are characterized by high productivity, precision of processing and for a long time pleases their owners. Also it is necessary to determine in advance with the expected scope of work and take into account the following parameters:

• Size of the sole. The processing of hard-to-reach surfaces is simplified when using a tool with a small sole having a triangular shape. In this case, the vibrating grinder with a larger working surface is optimally suited for volumetric surfaces and intensive operation.
• Frequency of oscillations. As the amplitude increases, the accuracy of processing improves and productivity increases.
• Power. Vibrating sanding machine Can have a power of 150 to 600 watts. The average will be enough for standard works. Tools with a large capacity are quite heavy and inconvenient to work with.

Makita BO3711

Despite the fact that the Makita shaker is positioned as a tool for processing large areas, it has compact dimensions and fits easily in the palm of your hand. Dimensions of the plate itself are 102x112 mm. It is possible to use both ordinary sandpaper and grinding sheets equipped with Velcro. Fixation is provided by special clamps located on both sides.

The design consists of two main parts: an ergonomic handle, supplemented with an insert of rubber to prevent slipping of the hand, and a working sole. At the top of the case there is a switch hidden behind the silicone cover. Paper fasteners have a simple but reliable design.

It is worth noting the presence of rubber wire with double insulation, which is typical for equipment with a higher cost.

Dust removal can be performed via an adapter using a vacuum cleaner. If this is not possible, you can use the dust bag that comes with the kit.

Bosch GWS Tool 20-230 H: Description

The Bosch grinder has many advantages over similar equipment. For example, a non-standard mounting option is used to fix the sandpaper. Devices of many brands are equipped with clamps or devices that are similar to paper clips. They not only quickly fail, but require constant attention, since uneven paper tension will lead to damage during work.

This tool uses a system called SheetLoc. Its design is represented by two levers, which ensure a tight fixation of paper on both sides, without any effort. It is enough to press the lever and place the abrasive under the locks. One of them is supplemented by a spring and allows you to stretch the paper evenly and tightly.

The tool cable has a sufficient length of 4 m. The weight is within 4 kg. The sandpaper used must have a size of 25x11 cm.

The Bosch vibratory grinders are equipped with a perforated and continuous grinding cavity, an adapter for connecting a vacuum cleaner and a dust container, which is supplemented by a microfilter.

Operation of Bosch GWS 20-230 H equipment

The device has a fairly large plate for processing about 22 cm in size, which makes it possible to polish surfaces with a larger area with less effort and time, and it is also much easier to work with edges. If necessary, in the final processing of furniture facades and door leaves this tool will be the best solution. In order to get started, just connect the device to the network and fix half the sheet of sandpaper. Dust can be collected in two ways: by means of a microfilter tank or a standard vacuum cleaner, for which an adapter, also included, is used. The container has a paper filter element, on which remains most of the smallest particles, a special hole with a lid is used to remove dust.

The machining process is not difficult, the Bosch GWS 20-230 H sanding machine is turned on with a special trigger, which can then be fixed. To the right of it is the speed regulator. Between the working mechanism and the body of the device itself there are special gaskets, which reduce the level of vibration, therefore practically it is not felt during processing.

"Interskol USHM-125"

The Interskol grinder differs from other devices in the form of an active built-in dust removal system. The engine has an additional impeller, which ensures the passage of airflow through the holes, which is then sent to the branch pipe. In order to ensure that all dust is in the dust receptacle, it is necessary to attach the filter element to the nozzle and add the abrasive sheet to the holes having the opposite arrangement of the holes of the platform. With intensive use, the best option is to connect the device to the vacuum cleaner using an adapter.

The electronic switch provides the possibility of adjusting the oscillation frequency. Grinding machine "Interskol USHM-125" belongs to the category of universal tools suitable for various jobs, but in a professional environment it is used, as a rule, to perform finishing operations.

Grinding machine "Interskol": features

The equipment is easy to operate: the abrasive element, which can have any base, is fixed to the sole with two clamps, after which the surface to be treated is carefully smoothed. It should be noted that in the course of the work it is necessary to constantly move the tool along the entire plane of the workpiece without exerting excessive pressure on it and not stopping in one place. The average level of productivity of the tool allows to achieve an optimum result. At the same time, it is economical and prevents clogging of the working space, naturally, on condition of competent use. The vibration grinder has a small mass equal to 2.4 kg, and its power is within 300 watts.
