Grinding is an abrasive machining process capable of achieving tolerances and surface finishes unattainable by any other process. When dimensional accuracy is unobtainable with milling, turning or electrical discharge machining (EDM), or when tolerances below ± inch are required, grinding steps in. Grinding can repeatedly deliver accuracy as tight as ± inch and do so repeatedly ...
