I have used Precision Granite for 20 years as our sole granite surface plate calibration service.

They have the capability to relap and certify all 54 plates in our shop. They also perform minor repairs on our granite plates. They are very prompt and complete the certificate in a fast, accurate, and timely manner. They do not disrupt our production schedules in any way. I would recommend them to be trustworthy and honest.
