Using the polishing technique allows you to finish work on metal, wood and stone blanks. The possibility of fine correction of edges gives the product accurate dimensional parameters suitable for specific tasks. Modern polishing machines are presented in different versions and models, differing in technical, structural and operational qualities.
Purpose of equipment
The simplest models are designed for finishing operations of building materials used in repair and installation activities. This mainly concerns working with solid materials that are impossible or difficult to change with another tool. In this way, for example, polishing of stone or porcelain tiles is carried out. These are finishing works, among the conditions for the implementation of which are accuracy and accuracy.
In industry and some workshops in the mode of in-line processing, such machines allow you to form parts and structural elements in accordance with the specified dimensions. Unlike cutters and waterjet, the felt polishing wheel provides correction down to the micron. Some models of machines with the use of special equipmentalso carry out textural artistic surface treatment.
Varieties
Usually, two classifications of this type of machine are used: according to belonging to the domestic or industrial field, and according to the target processing material. As for the first criterion, industrial models are provided with powerful engines, a strong frame with additional stops, overload protection and electronic stabilization systems. Home models, as a rule, have a small margin of power and are more operator-oriented in control. In accordance with the second classification, models are distinguished for working with wood, metal and stone. The smallest resource of power return is provided by a wood polishing machine, since in this case the structural accuracy of tool placement is of greater importance. Conversely, the processing of stone, metal and other solid workpieces is impossible without connecting a high-speed powerful electric motor.
How do polishers work?
Unlike polishing machines, the machine has a working platform (frame), which is fixed on a stable flat surface and does not change its position. The carrier metal base is placed on the platform, inside which the electric motor and spindles are installed. The power plant drives the shaft, which is the drive mechanism relative to the rotating equipment. As working materials, a leather or felt circle can be used forpolishing, as well as grinding abrasives.
For the physical regulation and control of the process, guide devices are used, and the angular gauge allows you to set the desired sharpening angle. Depending on the model, the unit may be provided with additional features. For example, the design often includes a small container for water to wet the disc during use. This addition is especially significant if long-term polishing of the stone is planned in a conveyor mode. If the tooling is not cooled, then the risk of its destruction will increase.
Features
To drive the machine, even in the case of industrial models, a low power motor is required - a maximum of about 700-950 watts. Most models are provided with 200 watt power plants. Accordingly, the equipment is connected mainly to a 220 V network. However, the regulation of the rotation speed and the number of revolutions is determined by different requirements for processing. It is one thing to maintain granite, and another to polish a piece of wood. The speed range varies from 90 to 150 rpm. The format of the circle also matters. If a metal polishing machine is used to perform sharpening, then the standard size will be 250 mm in diameter by 50 mm in thickness. Small circles and disks are used for fine refinement of small parts. The small area allows the tone to perform a jewelry finish.
Consumables and accessories
In addition to the directly working equipment inMachine maintenance and service may include power cable extensions, stabilizers, angle gauges, polishing pastes and covers. Auxiliary devices allow you to extend the life of the equipment and its components. Also, before buying a machine, it will be useful to look for a workbench for it. The stability and stability of the substrate on which the polishing machines operate is very important in terms of ensuring the quality of the operation and safety. The workbench must be a metal workbench with a metal supporting structure. Do not forget about personal protective equipment. Fine stone and metal dust from polishing is the most dangerous for the respiratory system. Therefore, in addition to gloves, glasses and an apron, it is desirable to have a respirator in service. And if the operation of the unit is accompanied by loud noise, then you should also get construction headphones.
Conclusion
Modern polishing machines rarely do just one function. Manufacturers strive to orient both the design and the power base for a wide range of operations. In particular, polishing machines are also capable of grinding, sharpening and, in some cases, cutting. Another thing is that the universal optimization of the machine may not have the best effect on the quality of each operation individually. As for the cost of polishing equipment, on average it is 7-10 thousand rubles. In the professional class, you can also find models for 20-25 thousand, but this segment is narrowly focused and in mostcases offers combined units with additional features. For home needs, you can limit yourself to a machine for 5-7 thousand, which will allow you to sharpen the tool, if necessary, modify the edges of the tile, and also decorate the wooden surface with an individual texture.
