Grinding disc

Resinoid-bonded diamond grinding discs are often used for grinding tungsten carbide or HSS tools, as well as other production grinding processes. They are used in both wet and dry grinding. Phenolic resin bond for dry grinding at very high stock removal rates. The PHST bond type can withstand higher loads, i.e. it allows a higher infeed per stroke without thermal damage to the workpiece. Inevitably, the reduction in grinding time with this bond is obtained at the expense of a slightly shorter tool life.
