Tight Tolerance Grinding That Meets Critical Inspection Demands

quality inspection

Whether you need a small, custom job or large lot sizes, Custom Production Grinding has the skills and capacity needed to provide tight tolerance grinding to 0.0002 inch with consistent, proven accuracy.

Our trained quality control professionals have exceptional expertise in ensuring the parts we grind always meet our customers’ exacting standards.

At Custom Production Grinding, quality control runs through the entire process — from set-up to job completion. During grinding, parts are subject to continuous monitoring for accuracy.

Our climate-controlled shop also helps ensure that the parts we grind meet exacting specifications. Rigorous control of the climate ensures that parts won’t expand or contract due to temperature fluctuations. Our two quality control centers each have their own HVAC systems to further regulate climate in those rooms.

Our operations are ISO-certified.
