    Selecting which of the following grinding operations to be used is determined by the size, shape, features and the desired production rate. Creep-feed grinding (CFG) was invented in Germany in the late 1950s by Edmund and Gerhard Lang. Unlike normal grinding, which is used primarily to finish surfaces, CFG is used for high rates of material removal, competing with milling and turning as a manufacturing process choice. Depths of cut of up to

    Grinding wheel wear is an important measured factor of grinding in the manufacturingprocess of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes. The grinding process itself has been compared to machining operations which employ multipoint cutting tools. The abrasive grains which make up the entire geometry of wheel act a

  • What Is Single Point OD Grinding? : Modern Machine Shop

    Single point grinding is a unidirectional process. Grinding of OD workpiece features progresses from right to left or vice versa. "Wheel wear is the reason for this process requirement," says Mr. Lipphardt. "Wear tends to migrate across the face of the grinding wheel. Therefore to achieve consistent contact, grinding needs to be unidirectional."
