摘要:
Abrasive tools with a mixture of more than 9% but less than about 65% superabrasive and from about 56% down to 0.5% of a microcrystalline alumina in a bond material show surprising advantages.
摘要:
A process is described for the production of bonded abrasive products in which the abrasive particles are filamentary alumina particles with a substantially uniform cross-section and an aspect ratio of at least about 1:1.
摘要:
Resinoid and vitrified bonded abrasive products containing filament shaped sintered alumina based abrasive made up predominantly of fine alpha alumina crystals.
摘要:
Vitrified bonded grinding wheels which contain a mixture of sintered sol gel aluminous abrasive and silicon carbide abrasive are substantially and surprisingly better than those with either abrasive component alone, in their ability to abrade certain metals.
摘要:
Resinoid and vitrified bonded abrasive products containing filament shaped sintered alumina based abrasive made up predominantly of fine alpha alumina crystals.
摘要:
An abrasive product and process is disclosed, for grinding titanium metal and its alloy. The product used to grind the titanium consists of a grinding wheel wherein the abrasive grains are aggregates of silicon carbide particles bonded together with a refractory bond such as silicon oxynitride or a silicate based material.
摘要:
Abrasive articles are disclosed comprising at least about 10% by volume of a superabrasive, such as CBN, along with a sintered sol gel aluminous abrasive component.
摘要:
Bonding of sintered sol-gel aluminous abrasive grits, comprising sub-micron sized alpha alumina crystals, in vitrified (ceramic) wheels results in abrasive performance superior to premium grade fused alumina in grinding tool-steels. Viscosity of the bond and/or temperature of firing must be controlled to avoid reaction between the bond and the abrasive.
