What types of polishing machine are there?

The main types of grinders are disc grinders, rotary grinders and various special grinders.

1、Disc type grinder
There are single-disc and double-disc types, and the double-disc lapping machine is the most commonly used. In the double-disc lapping machine, several workpieces are put into the cage located between the upper and lower grinding discs at the same time, and the cage and the workpiece are moved in parallel by the eccentric or planetary mechanism with the action plane. The lower grinding disc rotates and the upper disc parallel to it can either not rotate or rotate in the opposite direction to the lower disc and can be moved up and down to compress the workpiece (with adjustable pressure). In addition, the upper grinding disc can be rotated around the column at an angle with the swingarm for loading and unloading the workpiece.
The double-disc grinder is mainly used for machining two parallel surfaces, one flat surface (with additional attachment for pressing the workpiece), external cylindrical surface and spherical surface (with grinding discs with V-groove), etc. When processing external cylindrical surfaces, because the workpiece has to slide and roll at the same time, the cage hole slot type and arrangement angle must be reasonably selected. The single-disc grinder has only one lower grinding disc for grinding the lower plane of the workpiece so that workpieces of different shapes and sizes can be processed on the same disc with high grinding accuracy. Some grinders also have a mechanism that can automatically correct the grinding disc during the grinding process.

2、Rotary shaft type grinder
The workpiece or the grinding tool (adjustable grinding ring or grinding rod) is driven by the forward and reverse rotating spindle, with a simple structure, used for grinding internal and external cylindrical surfaces.

3、Specialized grinding machine
Depending on the workpiece to be ground, there are center hole grinders, steel ball grinders and gear grinders, etc. In addition, there is a kind of a centerless grinder that adopts a similar principle of centerless grinding and is used to grind cylindrical workpieces.

4、Three-roller lapping machine
Main uses and performance characteristics.
The three-roller mill is a wet grinding and crushing machine widely used in paint, coating, dyestuff, ink, plastic, leather, rubber, lead core, medicine, food, cosmetics and insulating materials and other chemical industry raw materials, the machine has a variety of functions such as crushing, dispersing, emulsifying, homogenizing, color mixing, recycling waste, etc. It is widely used in scientific research, testing, formulation and crushing micro debugging production.
The main components of this machine are three rollers, using Cr12 steel for strengthening protection treatment, anti-wear hardness up to HRC52 °-58 °, the surface rough hardness up to 0.2-0.1, the machine is easy to operate, easy to change color, beautiful appearance, low noise, favorable prices, used for grinding practice of various materials.
Structure parts: This machine mainly consists of (1) body (2) electrical switch (3) discharge plate (4) roller (5) gear material plate (6) adjustment system (7) transmission system (8) motor. A total of eight components.
Working principle: the raw material is added to the natural hopper composed of two rollers and two file material plates, and then the opposite asynchronous rotation of the two groups in the middle and after, which produces sharp turning of the raw material, shearing, destroying the structural stress between the molecules of the raw material surface crushing, and then the secondary grinding by the middle and front connecting rollers at high speed, and then achieve a high-speed uniform mixing of various raw materials.

5、Automatic grinding machine
1, automatic grinding machine is also high-speed grinding machine, precision grinding machine. Adopt abrasive cloth belt, electrical appliances adopt Japan and spring, Fuji, the whole machine spraying plastic, the color is microcomputer color.
2、The guide rail is a linear guide rail.
3、The scraping rubber adopts the card lock design, which can make the deformation scraping rubber to be adjusted correctly and ensure the grinding quality.
4、This automatic grinding machine, high-speed grinding machine, precision grinding machine can be used for the mechanical scraper and manual scraper grinding.
5、Special grinding wheel design, grinding cloth with no pressure, no deformation of scraping rubber, no ripple phenomenon, to ensure grinding precision.
6、Grinding angle degree to match the performance of various special printing.
7、The grinding machine is equipped with a dust washing device, which can reduce industrial pollution and is beneficial to the health of the staff and the maintenance of the equipment.
8、Automatic grinding machine, high-speed grinding machine, precision grinding machine is easy to operate, no need for professional skills to operate.
