Wear Plates - CMF Techinkz

Wear Plates is a solid, flat plate used as the main horizontal reference plane for precision inspection, marking out (layout), and tooling setup.[1] The surface plate is often used as the baseline for all measurements to the workpiece, therefore one primary surface is finished extremely flat with accuracy up to 0.00001 in or 250 nm for a grade AA or AAA plate.

There are varying grades used to describe the accuracy of some metrology equipment such as: AA, A, B and Workshop grade. While workshop grade is the least accurate, the plates are often held to a high degree of flatness.
