LK Metrology Bridge Coordinate Measuring Machines
Consistent sub-micron accuracy demands materials engineered to resist the variables that compromise measurement integrity – thermal fluctuation, structural deformation, and mechanical wear.
LK Metrology’s all-ceramic bridge and spindle construction addresses each of these directly, delivering exceptional thermal stability and long-term repeatability from compact entry-level systems to the world’s largest bridge-type Coordinate Measuring Machines (CMMs).
