Surface treatment with the help of this equipment is provided by abrasive paper with different grain sizes, which is placed on a rectangular sole producing high-frequency reciprocating movements. The vibration grinding machine is distinguished by a gentle processing method and at the same time high productivity, while it is possible to remove a layer of dirt and rust from the recesses, use it for working with products that have a corrugated or uneven surface.
Use cases
The device can work in several modes, each of which has a certain level of vibration. It is used for the final processing of plastic, metal, stone and wooden blanks. Grinding can be fine or coarse, depending on the grain size of the sheets used. Vibratory Grinders 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 grain sizes. 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 is Velcro, necessary for reliable attachment to the sole of the tool and quick replacement with abrasive elements of a different kind.
On many devices, you can use ordinary sandpaper, fixing with special clamps. The main thing is to pre-make holes on it to remove dust.
Complex surface treatment
Some vibratory grinders allow you to work with products, part of the surface of which has complicated access. This is achieved by equipment in the form of a modernized sole made in a triangular shape. It becomes indispensable when working with window frames and antique products. It is also convenient to use on a small plane. She easily processes small grooves, grooves and edges. It is worth noting that instead of the sole, a special grinding element can be installed, which allows to process 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 are worth exploring in order to make it easier to decide on the desired model. Most of the devices in the middle price segment are characterized by high performance, precision processing and for a long time pleases their owners. It is also worthwhile to determine in advance the estimated amount of work and take into account the following parameters:
- Sole size Machining hard-to-reach surfaces is simplified by using a tool with a small sole having a triangular shape. At the same time, the vibration grinder with a larger work surface is optimally suited for volume surfaces and intensive use.
- Oscillation frequency. With increasing amplitude, processing accuracy improves and productivity increases.
- Power. Vibratory Grinder can have power from 150 to 600 watts. An average value will be sufficient for standard work. Tools with high power are quite heavy and inconvenient to use.
Makita BO3711
Despite the fact that the Makita vibratory grinder is positioned as a tool for processing large areas, it has compact dimensions and fits easily in the palm of your hand. The dimensions of the plate itself are 102x112 mm. You can use both ordinary sandpaper and sanding sheets equipped with Velcro. Fixing is provided by special clamps located on both sides.
The design consists of two main parts: an ergonomic handle, complemented by a rubber insert to prevent slipping of the hand, and a working sole. In the upper part of the case there is a switch hidden behind a silicone cover. Paper fasteners have a simple but reliable design.
It is worth noting the presence of a rubber wire with double insulation, which is typical for equipment with a higher cost.
Dust removal can be done through an adapter with a vacuum cleaner. If this is not possible, you can use the dust bag provided.
Bosch GWS 20-230 H tool: description
The Bosch grinder has many advantages over similar equipment. For example, to fix sandpaper, a non-standard mounting option is used. Devices of many brands are equipped with clamps or devices that resemble staples. They not only quickly fail, but also require constant attention, since uneven tension of the paper will lead to damage during operation.
This tool uses a system called SheetLoc. Its design is represented by two levers that provide a tight fixation of the paper on both sides, while not requiring any effort. It is enough to press the lever and place the abrasive under the clips. One of them is supplemented with a spring and allows you to pull the paper evenly and tightly.
The tool cable has a sufficient length of 4 m. The weight is within 4 kg. The used sand paper should have a size of 25x11 cm.
Bosch vibration grinders are equipped with a perforated and continuous grinding cavity, an adapter for connecting a vacuum cleaner and a dust container, which is complemented by a microfilter.
Operation of equipment Bosch GWS 20-230 H
The device is distinguished by a rather large plate for processing with a size of about 22 cm, which makes it possible to polish surfaces with a larger area with less effort and time, and it also becomes noticeably easier to work with edges. If necessary, in the final processing of furniture facades and door leafs, this tool will be the best solution. In order to get started, just connect the device to the network and fix half a sheet of sandpaper. Dust collection can be carried out in two ways: using a container with a microfilter or a standard vacuum cleaner, the adapter, which is also included in the kit, is used to connect it. The container has a paper filter element on which most of the smallest particles remain; a special hole with a lid is used to remove dust.
The processing process is straightforward, the Bosch GWS 20-230 H grinder is turned on with a special trigger, which can then be locked. To his right is the speed controller. Between the working mechanism and the body of the device itself, special gaskets are placed that reduce the level of vibration, so it is practically not felt during processing.
Interskol UShM-125
The Interskol grinder differs from other devices in its equipment in the form of an active integrated dust removal system. The engine has an additional impeller, which ensures the passage of air flow through the holes, which subsequently goes into the pipe. In order for all the dust to be in the dust collector, it is necessary to attach the filter element to the nozzle and supplement the abrasive sheet with holes having an arrangement opposite to the platform openings. With intensive use, the best option is to connect the device to a vacuum cleaner using an adapter.
An electronic switch provides the ability to adjust the frequency of oscillation. The Interskol UShM-125 grinder belongs to the category of universal tools suitable for various works, but in a professional environment it is used, as a rule, for finishing operations.
Grinder “Interskol”: features
The equipment is easy to operate: the abrasive element, which can have any base, is fixed on the sole with two clamps, after which the surface to be processed is carefully smoothed. It is worth noting that during 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 you to achieve optimal results. At the same time, it is economical and prevents clogging of the workspace, of course, subject to proper use. The vibration grinder has a small mass of 2.4 kg, and its power is within 300 watts.
