To demystify the process, here are seven basic principles related to centerless grinders. 1. Deceptive simplicity combined with peerless precision. Centerless grinding works thanks to a few basic principles of physics. A grinding wheel and a regulating wheel hold the workpiece in place on a stationary work rest throughout the grinding process.
The process is preferred for manufacturing where a large number of work pieces must be handled and processed in a relatively short period of time. Centerless grinding is a process that has been a part of manufacturing for nearly 100 years. The process helps solve one of the limitations of other types of turning machines such as lathes and mills.
