Surface treatment with this equipment is provided by abrasive paper with different grits, which is placed on a rectangular soleplate, producing reciprocating high-frequency motions. The vibratory grinder is characterized 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 to 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 finishing plastic, metal, stone and wood workpieces. Grinding can be fine or coarse, depending on the grit of the sheets used. grindersvibrators are 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 there is Velcro, which is necessary for secure attachment to the sole of the tool and quick replacement with abrasive elements of a different type.
On many devices, you can use ordinary sandpaper, fixing it with special clips. The main thing is to first make holes on it to remove dust.
Machining complex surfaces
Some vibration grinders allow you to work with products, part of the surface of which has difficult 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 antiques. It is also convenient to use on a small plane. It handles small grooves, grooves and edges with ease. It should be noted that instead of the sole, a special grinding element can be installed, which allows processing the smallest cavities and cracks. It has a standard locking mechanism, so there is no need for special tools when replacing it.
How to choose
On vibration grinders, reviews are worth studying in order toto make it easier to decide on the desired model. Most of the devices of the middle price segment are distinguished by high performance, processing accuracy and please their owners for a long time. It is also worth deciding in advance on the expected scope of work and taking into account the following parameters:
- Sole size. The processing of hard-to-reach surfaces is simplified when using a tool with a small sole that has a triangular shape. At the same time, a vibratory grinder with a larger working surface is optimally suited for volumetric surfaces and intensive use.
- The oscillation frequency. As the amplitude increases, processing accuracy improves and productivity increases.
- Power. The vibration grinder can have a power of 150 to 600 watts. The average value will be sufficient for standard work. High power tools are quite heavy and awkward to use.
Makita BO3711
Despite the fact that the Makita vibratory sander is positioned as a tool for processing large areas, it has a compact size and fits easily in the palm of your hand. The dimensions of the plate itself are 102x112 mm. It is possible to use both ordinary sandpaper and sanding sheets equipped with Velcro. Fixation is provided by special clips 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. ATOn the top of the housing there is a switch hidden behind a silicone cover. Paper fasteners have a simple but reliable design.
Worth noting is the presence of double insulated rubber wire, which is typical for higher cost equipment.
Dust can be removed through the adapter using a vacuum cleaner. If this is not possible, you can use the supplied dust bag.
Bosch GWS 20-230 H tool description
The Bosch grinder has many advantages over similar equipment. For example, a non-standard mounting option is used to fix sandpaper. Many brands of appliances are equipped with clips or devices that look like paper clips. They not only fail quickly, but also require constant attention, as uneven paper tension will damage the paper 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, without any effort required. It is enough to press the lever and place the abrasive under the clamps. One of them is supplemented with a spring and allows you to stretch the paper evenly and tightly.
The cable of the tool has a sufficient length of 4 m. The weight is within 4 kg. The sandpaper used should be 25x11 cm.
Bosch vibratory grinders are equipped with perforated and solid grindingcavity, an adapter for connecting a vacuum cleaner and a dust container, which is supplemented with a microfilter.
Operation of equipment Bosch GWS 20-230 H
The device features a sufficiently large plate for processing with a size of about 22 cm, thanks to which it becomes possible to polish surfaces with a larger area with less effort and time, and it also becomes noticeably easier to work with edges. If you need the final processing of furniture facades and door panels, 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, for which an adapter is used, which is also included in the kit. 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 not difficult, the Bosch GWS 20-230 H grinder is turned on with a special trigger, which can then be fixed. To the right of it is the speed control. Between the working mechanism and the body of the device itself, special gaskets are placed that reduce the level of vibration, so during processing it is practically not felt.
“Interskol UShM-125”
Grinding machine"Interskol" differs from other devices by its equipment in the form of an active built-in dust removal system. The engine has an additional impeller, which ensures the passage of air flow through the holes, which is subsequently directed to the nozzle. In order for all the dust to end up in the dust collector, it is necessary to attach the filter element to the nozzle and supplement the abrasive sheet with holes that have an arrangement opposite to the holes of the platform. With intensive use, the best option would be to connect the device to a vacuum cleaner using an adapter.
Electronic switch provides the ability to adjust the oscillation frequency. The grinder “Interskol UShM-125” belongs to the category of universal tools suitable for various jobs, but in a professional environment it is usually used to perform finishing operations.
Grinder "Interskol": features
The equipment is easy to use: the abrasive element, which can have any base, is fixed on the sole with two clamps, after which the surface to be treated is carefully smoothed. It is worth noting that during the work it is necessary to constantly move the tool over the entire plane of the workpiece, without exerting excessive pressure on it and without stopping in one place. The average level of performance of the tool allows you to achieve optimal results. At the same time, it is economical and prevents clogging of the workspace, of course, whencondition of proper use. The vibration grinder has a small mass equal to 2.4 kg, and its power is within 300 W.
