Ace Granite Surface Plate Company originated the “In-Plant” calibration, certification and resurfacing service for surface plates to save users costly crating and shipping expense, as well as loss of use of plates in transit. We do on-site Calibration, Resurfacing and Certification of Granite Surface Plates and Granite Accesories. We also manufacture Granite Surface Plates, Granite Accesories and Custom Granite Machine Bases.

An owner of any brand granite surface plate can now have their plate calibrated and certified, or resurfaced and certified in their own plant… or ACE Granite will resurface it in our modern air conditioned plant and furnish a Certified Plate on loan, at no charge, while the customer's plate is in our plant.
