Polishing machines, also known as grinders, are often used for mechanical grinding, polishing, and waxing. The working principle is: the motor drives the polishing wheel installed on the polishing machine to rotate at high speed, and friction with the surface to be polished under the joint action of the polishing wheel and polishing wax, and then the purpose of removing paint pollution, oxidation layer and shallow marks can be achieved. The speed of the polishing wheel is generally 1500-3000 r/min, which can be adjusted at any time according to practical needs.
Mechanical polishing machines can be divided into two categories, manual and automatic, and the following is a brief description of the two types of polishing machines.
Manual polisher
1.Vertical motor polisher with wheels
This type of polisher is usually fixed to the ground, and is generally divided into single and double heads, and can be fitted with a sand belt and a polishing wheel. The polisher needs to sit or stand next to the machine to hold the workpiece for friction polishing. This polishing method is suitable for regular shaped or large pieces of work. There are also small, low-power desktop polishers for polishing small pieces of work, such as jewelry, or small pieces of hardware.
2.Hand-held polisher
This type of polishing machine is small, portable in use, the polishing wheel is placed on a drill, and requires the worker to hold the mechanical polishing wheel in contact with the surface of the workpiece for polishing. It is mainly used for regular or irregular polishing, large or small pieces of work, or for some DIY polishing operations.
Automatic polisher
The automatic polishing function increases work efficiency while maintaining stable quality and automation without labor, which is mainly divided for the shape of the workpiece.
1.Flat polisher
For flat pieces, a flat table can be used, which can be moved forward and backward, and swung from side to side. The workpiece is placed on a workbench, and the workpiece is polished automatically by an upper polishing wheel. For more complicated pieces, a corresponding fixture needs to be installed, and the piece is secured to the fixture and polished.
2.Tube polisher
Round-tube polishing machines are mainly divided into groups of single-tube conveying round-tube polishing machines and rubber roll round-tube polishing machines.
At present, there are mainly six groups, ten groups, twelve groups of round tube polishing machine, using the transport method can only be polished one, because the transport polishing and multi-grinding head polishing, the effect is better, will not affect the efficiency, and the length of the round tube is not limited, can be polished longer pipe. The number of heads can be specified when ordering according to the original condition of the work surface and the finish requirements of the finished product surface.
A round tube polisher with a rubber roll is made by mounting a rubber roll on a work surface and placing the round tube to be polished on the roll. The rubber roll can be rotated to drive the circular tube around, and the polishing wheel on the work surface is pressed down for polishing.
3. Disc polisher
There are mainly the following categories of grinding machines of this type: two-head disk grinders, four-head disk grinders, and six-head disk grinders. The disk polishing machine is mainly composed of a disk, polishing column (the number of polishing column is determined according to the processing technology of the product), electric control box and grinding agent supply system.
The motion of the disc can be made intermittent or continuous depending on the processing product, and it is equipped with a frequency converter to control the speed of the disc. The polishing wheel on the polishing column can be multi-axis positioned to meet the polishing of different sides of the product. Depending on the process requirements of the product, the product can be sanded, rough-thrown, fine-thrown, fine-thrown and other flow operations and appropriate choices can be made for polishing the posts. It is self-compensating when the hemp and cloth wheels wear out, and it is equipped with an automatic wax-spraying device. The fixture is designed with an automatic loading and unloading device, which is very convenient to operate.
4. CNC polishing machine
CNC polishing machines are also known as CNC grinders, CNC knife grinders, and CNC polishers. CNC polishing machines servo constant pressure polishing, instant compensation for consumable loss, polishing disk driven by independent motor rotation, positive and negative rotation automatically switched to meet the needs of different processes.
