Universal CNC Grinders
Our Universal CNC Grinders allow for internal and external workpiece dressing up to Ø400 mm, and face grinding, at simple jig. Maximum length of workpiece is 300 mm, or 750 mm for the long machine – EGM 350 L.
Do you need help choosing the right machine? Let us know what piece you wish to work and send over the drawing – we recommend the right machine, and suggest the best jig setting and dressing.
