{"id":"dmg-mori-nh-4000-dcg","model_id":"NH 4000 DCG","name":"DMG MORI NH 4000 DCG","summary":"The NH 4000 DCG is a DMG MORI machining center with X-, Y- and Z-axis strokes of 560 mm, 560 mm and 630 mm. It uses DCG (Direct Drive Motor) technology on the rotary axis, which the document describes as achieving zero backlash, high-speed rotation and high-precision indexing. It is programmed through a MAPPS Fanuc control and accepts workpieces up to 630 mm diameter, 900 mm height and 400 kg.","study_notes":["Max. X-axis stroke: 560 mm (22 in).","Max. Y-axis stroke: 560 mm (22 in).","Max. Z-axis stroke: 630 mm (25 in).","Max. workpiece diameter: 630 mm (25 in); max. workpiece height: 900 mm (35 in); max. workpiece weight: 400 kg (882 lbs).","Control and software alternative stated: MAPPS Fanuc (not listed in the available controller entries).","Machine height 2,711 mm (106.7 in); machine width x depth 2,397 x 4,004 mm (94.4 x 157.6 in).","Document states the space-saving design reduces required floor space by 11.1% compared with existing machines.","Rotary axis uses a direct drive motor with zero backlash; the document claims less maintenance and longer product life.","DCG technology is stated to give longer tool life, improved surface quality and roundness, and higher acceleration."],"safety_notes":[],"sources":[{"url":"https://en.dmgmori.com/products/machines/milling/horizontal-milling/nh/nh-4000-dcg","title":"NH 4000 DCG - Horizontal Milling - 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_mill","manufacturer":"dmg-mori","controllers":[],"travel_x_mm":560,"travel_y_mm":560,"travel_z_mm":630,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dmg-mori-nh-4000-dcg","license":"https://creativecommons.org/licenses/by/4.0/"}
