Diamond grinding tool disc hardness 30-40 Rockwell machined parts.

Description

Diamond, which is a mineral composed of carbon elements, is an allotrope of graphite, with a chemical formula of C, and is also the original body of common diamonds. Diamond is the hardest substance naturally occurring in nature.

The chemical composition of diamond is C, which is a homogeneous and polymorphic variant of carbon with graphite. In the chemical composition of minerals, it always contains elements such as Si, Mg, Al, Ca, Mn, Ni, and often contains impurity elements such as Na, B, Cu, Fe, Co, Cr, Ti, and N, as well as carbohydrates.

The crystal structure of diamond mineral belongs to the equiaxed tetrahedral structure of homopolar bond. The carbon atoms are located at the corners and the center of the tetrahedron and have a high degree of symmetry. The carbon atoms in the unit cell are connected by homopolar bonds with a distance of 154pm. Common crystal forms are octahedron, rhombic dodecahedron, cube, tetrahedron and hexaoctahedron, etc.

What are the Diamond Grinding Disc replacement conditions?

1, wear problem

Any grinding wheel has its certain use and wear requirements. If the wear condition reaches a certain level, it must be replaced with a new one. It can not be used in order to save material, it is an extremely unsafe violation. Generally, when the grinding wheel wears to a diameter 10mm larger than the diameter of the chuck, it should be replaced with a new one.

2, validity period

The new wheels removed from the warehouse are not necessarily qualified wheels, and even new wheels purchased from manufacturers are not necessarily qualified wheels. Any grinding wheel has a certain expiration date. If it is used within the expiration date, it is a qualified grinding wheel; if it is used beyond the expiration date, it is not necessarily a qualified grinding wheel. The regulations stipulate that "the grinding wheel should be used within the validity period, and the resin and rubber bond grinding wheel must be subjected to a rotation test after storage for one year before it can be used".

3, texture issues

If cracks are found in the grinding wheel during use, you should stop using it immediately and replace it with a new one, so as to avoid accidents caused by grinding wheel breakage.
