In 2016, we applied for a patent for a high quality metal grinding disc.
The invention belongs to the field of coated abrasives, and discloses a surface-polished diamond grinding disc, wherein the polishing abrasive layer is bonded to a substrate, wherein the polishing abrasive layer comprises 20 to 50 parts by weight of diamond powder, 20 to 40 parts by weight of a binder, and 10~30 parts by weight of filler is prepared. The invention also discloses a preparation method of the diamond grinding disc.
The invention uses the diamond micropowder as the polishing abrasive, the inherent high hardness, wear resistance and high thermal conductivity of the diamond, greatly improving the sharpness and the service life of the grinding tool; and the electric driving tool such as the electric angle grinder can be installed for polishing and grinding. The working environment is highly adaptable, and the processing efficiency is higher, and the precision is significantly improved compared with the flocking grinding disc, and is suitable for polishing and polishing various non-metal materials.
Sovereign item: a surface-polished diamond grinding disc comprising a substrate and a polishing layer, wherein the polishing layer is bonded to a substrate, the polishing layer consisting of 20 to 50 parts by weight of diamond powder, 20 It is prepared by using 40 parts by weight of a binder and 10 to 30 parts by weight of a filler.
