Features

1. GH200 CNC6 is of 6-axis with four axes coordinated control. CNC axes: A-axis--hob head swivel; B-axis--spindle rotation; C-axis--worktable rotary motion; X-axis--radial feed motion; Y-axis--tangential feed motion (or hob shifting motion); Z-axis--axial feed motion;

2. Four coordinated control axes: B,C,X and Z (or B,C,Y and Z);

3. In case of power off or failure occurred, the column will quickly retract. The fault number will automatically display on the screen;

4. With vertical design, the column can move in radial direction as feed motion;

5. With symmetric and double-wall construction of machine bed, circulating coolant can ensure stable thermal distribution of the machine;

6. The spindle is driven by a large power servo motor through 2-stage super precision helical gearing, and a one-tooth difference clearance-eliminating mechanism at the terminal. The quick-change hob and automatic hob holder clamping devices are equipped. Auto spindle overload monitoring & alarm device is available;

7. New powerful pulling hob system is designed to greatly improve rigidity of the spindle;

8. Super precision helical gearing is adopted for the worktable to carry out high speed and super precision index. The machine is equipped with clearance-eliminating and damp adjusting mechanism;

9. Powerful input of circulating lubricant and compressed air ensure good cutting performance of the machine, tool and fixture, etc.;

10. Separated hydraulic and lubrication systems;

11. Equipped with hob, fixture and program quick change-over systems to carry out different kinds of the workpieces quick-change;

12. Finish machining accuracy comes up to grade 6-6-7 of the Chinese Standard GB/T100095, 1-2008.
