Abstract
Flute grinding cemented carbide workpieces with a diamond containing resin bond grinding wheel is improved by restricting the diamond to comprise a silver-coated diamond; conducting the grinding in the presence of a lubricant consisting of only straight oil; and conducting the grinding at a wheel speed of less than about 30 m/s and preferably about 20 m/s. The preferred diamond is coated with about 25% and 75% silver by weight.
