Mounted point is a general term for small shank grinding tools. It is usually widely used in electric grinders, hanging grinders, hand drills and other machinery; and there are many types of grinding heads, which can be distinguished from the material. Ceramic mounted point, rubber mounted point, diamond mounted point, abrasive cloth mounted point, alloy mounted point, etc. They are different types and their uses are different.
1. For the ceramic mounted point, the grain size sand is sintered by ceramic binder, and the grain size sand used is generally brown corundum, white corundum, chrome corundum, silicon carbide, etc. It is supplemented by a metal handle in the center, which is mainly used for grinding various metals. , for the grinding of the inner wall of the aperture and the correction of the mold.
2. The finer grained sand of the rubber mounted point is combined with a rubber binder to polish the mold.

3. The abrasive cloth mounted point is actually multiple pieces.The rectangular abrasive cloth is bonded around the metal handle, and the particle size is generally 60#-320#, which is used for polishing the inner wall of the aperture.

4. Compared with the above-mentioned mounted point, the diamond mounted point is more special, which includes a base body and several grinding bodies, among which several grinding bodies are fixed in the base body with gaps, and the grinding bodies also have gaps on the grinding surface of the mounted point. Among them, the matrix is preferably made of a bonding material with a certain toughness, and the grinding body is preferably made of a diamond alloy material.

The unique material makes the diamond mounted point not only has the advantages of high grinding performance, simple manufacturing and low cost, and high grinding quality, but also suitable for large-scale grinding, including cast iron, cast steel, carbon steel, and alloy steel, stainless steel, copper, aluminum and other metals as well as marble, jade, bone and other non-metals, the processing hardness can reach HRA≥85.
With these advantages, the diamond mounted point can basically replace the small grinding wheel with a shank. Compared with the small grinding wheel, it has no dust pollution and can process various high-precision shapes of mold cavities; and the whole process is easy to master, simple to use, safe and reliable.
