Centerless grinding is an abrasive cutting process to remove material from a workpiece. Similar to centered grinding except without a spindle. This method is favored by high volume operations because parts can be quickly inserted and removed from the process. High volume, high quality grinding is quickly becoming a lost art.


Intended for stock or near-stock engines and drive trains, 8.5:1 compression, 2.70 to 3.25 ring and pinion, automatic transmission with stock converter or four-speed manual transmission. If you are uncertain as to which cam profile best suits your needs, please contact our technical support staff at 619-661-6477.
