We regularly work closely together on projects from our quoting stage through delivery and involve them early in our processes to ensure both our success. One amazing project we worked on together was grinding stainless discs to a mirror finish. They run low volume through many thousands of pieces for us. Grind Lap is our go-to shop for grinding and honing.”

–Scott Kolar General Manager

“Grind Lap has helped us out with a customer that will not tolerate anything but what is on the print. Grind lap did the OD and ID grinding of these parts and held the parallel and perpendicular tolerances (.00003) to print. By doing that for us, our customer is now our best customer and gave us a lot more work.

We believe in Grind Lap for anything grinding.”
