Working principle of grinding disc

Grinding disc, which includes a top disc, a buffer plate and a grinding sheet; wherein the top disc includes several riveting elements, an upper positioning plate, a top plate, a bolt, a lower positioning plate and a nut; the utility model By improving the bolt structure, firstly, the locking part of the bolt itself is engaged with the central hole of the top plate to provide horizontal accuracy, and then a polygonal fixing part under the bolt is opposite to the polygonal fixing hole of the lower positioning plate. It can be locked for vertical accuracy, thereby providing a grinding disc with good fixation and rotation stability; in addition, the design of the upper thread section, the engagement part and the fixing part of the bolt with different outer diameters makes the bolt difficult Loosening has the advantages that the internal components are not easy to wear and the user does not cause soreness in the hands due to the unstable rotation of the grinding disc.

Characteristics and signs of superabrasive grinding discs

1. Abrasives and super-hard abrasives include natural diamonds and natural diamonds. There are many different grades.

2. Granularity. The granularity is mainly in accordance with the national standards. The size of various granularities of super-hard abrasives should be kept within a certain range.

3. The main function of the bonding agent is to control the ultra-hard abrasives and the abrasive tools to have the correct geometric shape. There are four main types of bonding agents for the ultra-hard abrasives.

4. Concentration is possessed by super-hard abrasives, which mainly shows the content of super-hard abrasives per unit volume. The content of abrasives contained in super-hard abrasives of different concentrations will also be different.
