Features
1. GH400 CNC6 is of 6 axes with 4 axes coordinated, CNC axes: A-axis: hob head swivel; B-axis: hob 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. Carry out index and differential compensation motions by electrical gear box. High speed heavy-duty hobbing with multi-start high speed hob can be carried out.
3. Quick-retraction protection: in case of power off or failure occurred, synchronously and quickly retract hob to avoid collision;
4. Compact construction design to save floor space; reasonable arrangement so as to operate easily.
5. Double-wall, rib-reinforced and symmetric construction design for bed and column ensures stable thermal distribution of the machine.
6. Large power AC spindle motor is used for the spindle; high precision helical gearing is adopted for transmission. One-tooth difference clearance-eliminating mechanism is arranged at the end of transmission chain.
7. Special spindle bearings are used for supporting the hob spindle; steel inserted guideway and ample rectangle guideway are used for slide; which ensures the machine has high rigidity and accuracy.
8. The quick-change hob and automatic hob holder clamping devices are equipped, also spindle overload auto monitoring and alarm device.
9. Super precision bearing are used for supporting worktable spindle; super precision double worm gearing system are used for worktable to carry out clearance-free transmission; a clamping cylinder is arranged at the bottom.
