{"id":"dmg-mori-nvgh-12t","model_id":"NVGH-12T","name":"DMG MORI NVGH-12T","summary":"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.","study_notes":["Max. grinding diameter is 1,200 mm (47 in.).","Max. workpiece height is 700 mm (28 in.).","Max. grinding length is 600 mm (24 in.).","Max. spindle speed of the work spindle is 200 rpm.","Grinding spindle is mounted on a turret with continuous indexing function (B-axis).","Optional work spindle C-axis gives continuous indexing at a minimum indexing unit of 0.0001 degrees using a direct drive motor.","Work spindle C-axis enables non-round grinding such as polygon and cam shapes, and curvic coupling by synchronous control of X and C-axis.","Hard turning function is an option: a turning spindle can be added for stock removal.","ATC has 8-tool storage for the internal grinding spindle.","Dresser unit uses a single point diamond; rotary dresser, R-shape dresser and AE sensor are options.","AMS (Automatic Measurement System) is available with various stylus options.","Automation options include SCARA robot, rotary stocker and APC (Automatic Pallet Changer); control and software alternative is listed as FANUC without a specific controller model."],"safety_notes":[],"sources":[{"url":"https://en.dmgmori.com/products/machines/grinding/vertical-grinding/nvgh/nvgh-12t","title":"NVGH-12T - Vertical Grinding by DMG MORI - DMG MORI","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":5,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"cnc_grinder","manufacturer":"dmg-mori","controllers":[],"spindle_max_rpm":6000,"spindle_taper":"HSK-A125","tool_capacity":8,"max_swing_mm":1250,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dmg-mori-nvgh-12t","license":"https://creativecommons.org/licenses/by/4.0/"}
