Based on new developments for specific customer requirements to determine form deviation of bearing rings, turntables, and cylindrical workpieces, the KNM 7C is a universally applicable high-precision measuring device. Its set-up as CNC-controlled 4-axis measuring equipment enables expanding to a larger range of parts such as highly complex gearing or 3D-measuring tasks on prismatic workpieces. All the components relevant for high-precision are made of dark granite. Air bearing guide elements are positioned in all axes ensuring a wear-free and smooth operation. Measuring uncertainty (according to DIN EN ISO10360) comes to MPEE ≥ 0,6 µm + L/400 and MPETHP ≥ 0,8 µm. The KNM 7C perfectly combines metrology features of a form measuring device with the strengths of a gear - respectively coordinate measuring machine. The sophisticated software with all-automatic measuring cycles is prerequisite for a direct closed-loop-system to the processing machine. This solution is offered according to Industry 4.0 requirements together with the KN 5Ci grinding machine.
