Machine concept

The KNM 4X analytical measuring machine is designed for high-precision measurements of gears, gear tools and rotationally symmetric workpieces up to a diameter of 450 mm.

All guides and base plates made of granite are extremely stable in the long-term and have identically low expansion coefficients. Air bearings with emergency operation properties ensure perfect and wear-free guides without short-term errors. Air spring elements underneath the base plates safely shield from jolts and vibrations. Separate bases are not required. Non-ferrous linear and torque motors of the rotary tables ensure ultimate position precisions and path accuracy.

Despite the compact design, spacious travel ranges ensure a tangential generating motion towards the base circle for any profile. The control cabinet can be arranged freely.
