CNC Universal Grinding Machine UGM Series

The UGM Series multiple grinding capability performs Cylindrical, Internal & Face Grinding with one chucking at the highest level of accuracy. High accuracy Universal Grinding Machine. Advanced technology for Universal Grinding compared to the stand alone Cylindrical and Internal Grinders The combination of a Plain approach OD spindle, Angle approach OD spindle and Internal spindle on a single turret base enables multiple cylindrical, face and internal grinding processes in one chucking. The automatic indexing system enables single chucking of the part to reduce part handling and optimizing throughput and accuracy. 1 UGM Series
