External cylindrical grinding is one of the most common grinding processes and is mainly used for grinding rotationally symmetrical workpieces. It differs in the type of workpiece clamping and feed directions: The most common type of clamping in external cylindrical grinding is between centers. This means that the workpieces must be centered at ...
Grinding operations: Cylindrical grinding 1. External cylindrical grinding (also called center-type grinding to distinguish it from centerless grinding) is performed much like a turning operation. 2. The cylindrical workpiece is rotated between centers to provide a surface speed of generally 18 to 30 m/min, and the grinding wheel rotating generally at 1200 to 2000 m/min, is engaged to perform ...
W. Brian Rowe, in Principles of Modern Grinding Technology (Second Edition), 2014. Flexible Grinding Operations and Peel Grinding. Flexible grinding operation suggests that a family of components or possibly several families can be produced flexibly on one automatically controlled machine tool. For example, it is possible that cylindrical components having several diameters and shoulders could ...
