Types and materials of diamond grinding disc
Diamond grinding disc is coated with synthetic diamonds bonded with composite materials.it is usually consists of a grinding layer, an adhesive layer and a nylon velvet fastener.
Types of diamond grinding disc:
1.Diamind cutting disc
2.Vitrified Diamond Grinding disc
3.Resin Diamond Grinding disc
4.Metal Bonded Diamond Grinding disc
5.Electroplated Diamond Grinding disc
Materials of diamond grinding disc are diamond and abrasives silicon carbide(some manufacturer use white fused alumina too).
Synthetic diamond is a mineral composed of pure carbon, which is produced by the reaction of carbonaceous raw materials such as graphite and certain metals (alloys) through high pressure and high temperature technology.
Silicon carbide includes black silicon carbide and green silicon carbide,is produced in electrical internal resistance furnaces from silica sands and petroleum coke(added salt during smelting),with high hardness,thermal conductivity and strength.
White fused alumina is also called white fused aluminum oxide,white corundum,made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase α-Al2O3.with higher hardness than brown fused alumina,lower toughnesss,high purity,good self-sharpness,strong grinding ability,low heat generation,high efficiency,wear corrosion and wear high temperature.
