The 3D photoelectric probe is a product with high-precision edge inspection and other functions. The alignment accuracy is higher, and the repeatability can reach 0.001MM. It has a more comprehensive Z- measurement function. Better precision retention with ceramic probes The larger amount of stylus swing prevents mistakes from causing damage to the probe. No conductive principle, not due to material. The machine tool spindle is not conductive and cannot be measured.
