{"id":"dmg-mori-nvgh-22t","model_id":"NVGH-22T","name":"DMG MORI NVGH-22T","summary":"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.","study_notes":["Control and software alternatives listed as FANUC; no specific FANUC controller model is named in the document.","Machine is a 1-spindle specification; the grinding spindle is carried on a turret with continuous indexing (B-axis).","Maximum grinding diameter is 2,200 mm and maximum grinding length is 600 mm.","Maximum workpiece height is 700 mm.","Work spindle maximum speed is 100 rpm; grinding spindle maximum speed is 6,000 rpm.","Hard turning function is an option: a turning spindle can be added for stock removal to reduce cycle time.","Work spindle C-axis is an option using a Direct Drive motor, with a minimum indexing unit of 0.0001 degrees; it enables non-round grinding such as polygon and cam shapes, and curvic coupling by synchronous X- and C-axis control.","ATC provides 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.","Automation options include SCARA robot, rotary stocker and APC (Automatic Pallet Changer); AMS (Automatic Measurement System) is available with various stylus options."],"safety_notes":[],"sources":[{"url":"https://en.dmgmori.com/products/machines/grinding/vertical-grinding/nvgh/nvgh-22t","title":"NVGH-22T - 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":2250,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dmg-mori-nvgh-22t","license":"https://creativecommons.org/licenses/by/4.0/"}
