Deliver remarkable improvements in finish bore size, geometry and surface finish with extremely tight tolerances held as close as .0002″ on most parts. Honing creates a high bearing area ratio, low surface roughness and a defined cross hatch pattern for lubricant retention.

Depending on your material and surface finish requirements, different stone materials can be used to meet your manufacturing specifications. We provide honing services for both thru-hole and blind-hole bores. Together, the members of our honing team have 110 years of experience.

Looking for high volume or a small lot of complex parts? We can help! Grind Lap provides superior quality, fast service and competitive pricing.
