# DMG MORI NH 4000 DCG

Hardware · `NH 4000 DCG` · verification: source checked

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.
