Internal measurements are possible thanks to the combination of centering and tilting table, a three-jaw chuck, for example, and the T7W tactile form probe system.

With the centering and tilting table, the Mar4D PLQ-T4 can test the same features as a classic form tester, for example axial runout.

For optical measurements , the centering and tilting table ensures that the matrix camera captures the edges of the workpiece much more accurately than with purely mathematical alignment.
