Precision Grinding Solutions for Sintered Metal Manufacturers

Powder metal comes off the press near net shape. Grinding is what brings the surfaces that seal, slide, and bear to final size.

Custom Production Grinding runs sintered and powder metal parts as regular production work, not as a specialty exception. Centerless thru-feed handles ODs from 0.125 to 4 inch at 0.0001 inch, with roundness under 0.0001 inch — the fit for pressed-and-sintered parts that need a final diameter no press can hold. Ten centerless machines mean a volume program runs as a standing job instead of queuing behind one-offs, and flat faces go on a 30 inch Blanchard rotary. If your sintered part needs a ground diameter, a flat face, or a honed bore, send the print.
