DMG MORI NVGH-22T

The NVGH-22T is a vertical multi-process CNC grinding machine. The workpiece sits vertically, with a swing diameter of 2,250 mm and a maximum grinding diameter of 2,200 mm, and grinding is performed by a single HSK-A125 grinding spindle mounted on a turret with a continuously indexing B-axis. An optional turning spindle allows hard turning for stock removal, and an optional direct-drive C-axis on the work spindle enables non-round grinding.
