Using the polishing technique allows finishing work on metal, wood and stone workpieces. The ability to fine-tune the 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 applies to working with solid-state materials that are impossible or difficult to change with another tool. In this way, for example, polishing of a stone or porcelain tile is carried out . These are finishing works, among which the conditions of fulfillment are accuracy and accuracy.
In industry and some workshops in the line processing mode, such machines allow the formation of parts and structural elements in accordance with the specified dimensions. Unlike carvers and waterjet, a polishing felt wheel provides correction down to microns. Some models of machines with the use of special equipment also carry out textural artistic surface treatment.
Varieties
Usually, two classifications of machines of this type are used: according to belonging to the household or industrial sphere, and according to the target material of processing. As for the first criterion, industrial models are provided with powerful engines, a strong bed with additional stops, overload protection and electronic stabilization systems. Home models, as a rule, have a small margin of power and are more likely to focus on the operator in management. In accordance with the second classification, models for working with wood, metal and stone are distinguished. The smallest resource of power return is provided by a wood polishing machine, since in this case the structural accuracy of the equipment placement is of greater importance. Conversely, the processing of stone, metal and other solid-state workpieces is impossible without connecting a high-speed powerful electric motor.
How are polishing machines arranged?
Unlike polishing machines, the machine has a working platform (bed), which is fixed on a stable flat surface and does not change its position. A supporting metal base is placed on the platform, inside of which an 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 wheel for polishing, as well as grinding abrasives, can be used.
Guiding devices are used for physical regulation and process control, 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, a design often provides a small container for water that moistens the disc during use. This addition is especially significant if long-term polishing of the stone is planned in the conveyor mode. If the equipment is not cooled, the risk of its destruction will increase.
Specifications
To bring the machine into operation, even in the case of industrial models, a low power engine is required - a maximum of about 700-950 watts. Most models are provided with 200W power plants. Accordingly, the equipment is connected mainly to the 220 V network. Nevertheless, the regulation of the rotation speed and the number of revolutions is determined by different processing requirements. It is one thing to maintain granite, and another to polish wood. The speed range varies from 90 to 150 rpm. The circle format also matters. If a metal polisher is used for sharpening, then the size will be 250 mm in diameter by 50 mm in thickness. For fine refinement of small parts, small circles and discs are used. A small area allows the tone to perform jewelry finishing.
Consumables & Accessories
In addition to directly working equipment in the maintenance and maintenance of machines, extension cords for power cables, stabilizers, tools for measuring angles, polishing pastes and covers can be used. Ancillary devices can 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 basis on which the polishing machines operate is very important in terms of ensuring the quality of operation and safety. The workbench should be metalwork 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 advisable to have a respirator in service. And if the operation of the unit is accompanied by a loud noise, then it is worth getting construction headphones.
Conclusion
Modern polishing machines rarely cost one function. Manufacturers strive to orient both the design and the power base under 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 oriented and in most cases offers combined units with additional features. For domestic needs, you can confine yourself to a machine for 5-7 thousand, which will allow you to sharpen the tool, if necessary, refine the edges of the tiles, as well as design a wooden surface with an individual texture.
