{"id":"dmg-mori-nvgh-3t","model_id":"NVGH-3T","name":"DMG MORI NVGH-3T","summary":"The NVGH-3T is a CNC vertical multi-process grinding machine. Two grinding spindles are mounted on a turret with a continuous-indexing B-axis: an internal grinding spindle with HSK-A63 interface and automatic tool change, and an external grinding spindle with a 355 mm grinding wheel. It handles workpieces up to 350 mm swing diameter, 450 mm height and 320 mm grinding length, with a grinding spindle speed of up to 20,000 rpm.","study_notes":["Swing diameter: 350 mm (14 in).","Max. grinding diameter: 350 mm (14 in).","Max. workpiece height: 450 mm (18 in).","Max. grinding length: 320 mm (13 in).","Max. work spindle speed: 800 rpm.","Two spindles on a turret with continuous indexing function (B-axis).","Internal grinding spindle: HSK-A63 with ATC function.","External grinding spindle: diameter 355 mm grinding wheel, fitted as standard.","Optional work spindle C-axis with Direct Drive motor gives continuous indexing at a minimum indexing unit of 0.0001 degrees; enables non-round grinding such as polygon and cam shapes, and curvic coupling by synchronous X and C-axis control.","ATC for the internal grinding spindle stores 6 tools.","Dresser unit with single point diamond; rotary dresser, R-shape dresser and AE sensor listed as options.","Control and software alternatives are listed only as FANUC; no specific controller model is named in the document. Automation options include a SCARA robot and rotary stocker, and an AMS (Automatic Measurement System) with various stylus options is available."],"safety_notes":[],"sources":[{"url":"https://en.dmgmori.com/products/machines/grinding/vertical-grinding/nvgh/nvgh-3t","title":"NVGH-3T - 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":20000,"spindle_taper":"HSK-A63","tool_capacity":6,"max_swing_mm":350,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dmg-mori-nvgh-3t","license":"https://creativecommons.org/licenses/by/4.0/"}
