Features
(1) Realize high-precision five-axis linkage machining
The GMU-400 Dreadnought series adopts a highly rigid fixed beam gantry structure to achieve high machining performance and contour accuracy under high dynamic conditions with high precision, performance and efficiency. More importantly, GMU-400 is also equipped with The proud GTRT gear drive cradle technology presents A-axis 1056Nm, C-axis 432Nm, from any difficult-to-cut material, to the high surface quality required by mold manufacturing, and even the almost demanding contour accuracy GMU-400 Dreadnought series achieve one by one.

(2) GTRT gear drive turntable technology
GMU-400 is equipped with GTRT gear drive turntable technology, which achieves stronger torque output, higher rigidity, stability and better rotation accuracy than conventional turntable drives.
