# DMG MORI NVGH-12T

Hardware · `NVGH-12T` · verification: source checked

The NVGH-12T is a CNC vertical multi-process grinding machine built as a single-spindle unit with an HSK-A125 grinding spindle carried on a turret with a continuous-indexing B-axis. It grinds workpieces up to 1,200 mm in diameter, 700 mm high and 600 mm long, with a work spindle running up to 200 rpm and a grinding spindle up to 6,000 rpm. Options include a turning spindle for hard turning, a direct-drive C-axis on the work spindle for non-round grinding, an 8-tool ATC for the internal grinding spindle, and automation such as a SCARA robot, rotary stocker or pallet changer.
