{"id":"dmg-mori-igh-7nt","model_id":"IGH-7NT","name":"DMG MORI IGH-7NT","summary":"The IGH-7NT is a CNC internal grinding machine for precision bore, face and taper grinding. A turret-type wheelhead carries one internal and one external grinding spindle, so ID, OD, face and taper grinding can be done in a single clamping. An NC swivel table on the headstock, set in 0.0001° increments by NC command, is standard equipment for taper grinding.","study_notes":["Max. grinding diameter is 275 mm (11 in.).","Max. grinding length is 450 mm (18 in.).","Max. workpiece length is 750 mm (30 in.).","The NC swivel table is equipped as standard on the headstock with a setting unit of 0.0001° by NC command, used for taper grinding.","A turret-type wheelhead carries one internal and one external grinding spindle, allowing ID, OD, face and taper grinding in one clamping.","Options include an automatic measurement device and a 4-spindle specification.","A single-spindle specification with fixed wheelhead (NE type) is available as an alternative to the multi-spindle specification.","An NC 3-axis loader is available as an option for automation.","The stated spindle_max_rpm value of 900 rpm refers to the work spindle.","Control and software alternatives are listed only as FANUC, without a specific controller model."],"safety_notes":[],"sources":[{"url":"https://en.dmgmori.com/products/machines/grinding/horizontal-grinding/igh/igh-7nt","title":"IGH-7NT - Horizontal Grinding by DMG MORI - DMG MORI","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":4,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"cnc_grinder","manufacturer":"dmg-mori","controllers":[],"weight_kg":7500,"spindle_max_rpm":900,"max_swing_mm":300,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dmg-mori-igh-7nt","license":"https://creativecommons.org/licenses/by/4.0/"}
