How We Control Dimensions: Calipers, Projectors and CMM Explained
Precision is not a promise, it is a measurement system. Here is how our three-level gauging strategy keeps tolerances stable from first article to shipment.
Level 1: Calipers and Micrometers for Patrol Checks
Simple, fast and everywhere on the floor. Patrol checks every two hours catch drift before it becomes scrap.
Level 2: Optical Projectors for Profiles
Projectors compare the real contour against the drawing overlay, ideal for bend angles and complex profiles.
Level 3: CMM for Critical Dimensions
the tightest features are verified on a coordinate measuring machine, with reports attached to every batch.
