High Precision 5 Axis CNC Milling Machine Tools GMU400 for Mold Processing
Introduction
Achieve high-accuracy five-axis simultaneous machining.
Featuring a high-rigidity fixed beam gantry structure, the GMU-400 Fearless series can realize high machining performance and contour accuracy under highly dynamic conditions with high accuracy, performance, and efficiency. More importantly, the GMU-400 is equipped with the outstanding GTRT gear transmission cradle technology as well to present an A-axis torque of 1056N.m and a C-axis torque of 432N.m. From any difficult-to-cut material to the highest surface quality required by mold manufacturing and even the nearly exacting contour accuracy, the GMU-400 Fearless series can deal with them perfectly.
Finite element analysis combined with dynamics optimization to ensure high rigidity, high accuracy, and high stability.
1. High-rigidity fixed-beam gantry structure is adopted to achieve excellent rigidity, thermal symmetric stability, and high-efficiency vibration suppression.
2. An integral cross beam with a closed section to eliminate redundant mass and achieve high rigidity.
3. Moving parts optimized in terms of weight to achieve perfect dynamic performance.
4. Z-axis optimized in terms of mechanics and dynamics to gain 30% more rigidity and dynamics than similar models.
5. Extra-large area of vertical column base to provide stronger rigidity and stability.
6. Finite element analysis, calculation and optimization of whole-machine structure and moving parts to achieve high milling efficiency, high machining performance, and extreme accuracy.
7. First-order natural frequency of the whole machine up to 67HZ, which has greatly improved the anti-seismic performance and the static and dynamic rigidity of the machine tools.
8. Three-axis acceleration up to 1.2G.
GTRT Gear Transmission Rotary Table Technology.
The GMU-400 has adopted the GTRT gear transmission rotary table technology for the first time in its class. Compared to the conventional rotary table drive ones, it can present greater torque output, higher rigidity, higher stability and better rotation precision.
