Main features:

This machine is a six-axis CNC gear hobbing machine, of which the CNC shafts are radial feeding shaft (X-axis), axial feeding shaft (Z-axis), tangential feeding shaft (Y-axis), toolpost angle rotating shaft (A-axis), hobbing cutter spindle rotating shaft (B-axis) and worktable rotating shaft (C-axis).

1. To adapt to the high-efficiency high-power machining of large modulus gears, the machine worktable housing is independently installed and is connected to the bed so that the cutting force can be directly transmitted to the firm foundation. The main drive of the worktable adopts double worm gear pair structure to eliminate the backlash and improve the drive stability and accuracy of the worktable.

2. To meet the requirements of different machining objects, this machine offers two types of toolpost structure at the user’s choice:

Standard toolpost: The motion of the hobbing cutter spindle AC servo motor is transmitted by two pulleys and high-precision gear pairs to the hobbing cutter spindle and a tooth difference anti-backlash mechanism is installed on the end gear of hobbing cutter spindle. The spindle is supported by special spindle combination rolling bearings of high stiffness and high accuracy to improve the drive stiffness and distortion/vibration resistance.

Large toolpost: The motion of the hobbing cutter spindle AC servo motor directly installed on the toolpost slide is transmitted by high-precision gear pairs to the hobbing cutter spindle and a tooth difference anti-backlash mechanism is installed on the end gear of hobbing cutter spindle. The hobbing cutter spindle support adopts static pressure bearings to improve the drive stiffness and distortion/vibration resistance.

3. The X-axis bed slideways adopt the combination slideways that integrate the steel-embedded slideway and injection molded sliding surface and the zero-clearance rolling block guide mode. The preload pressure plate mechanism is applied for the wide-plane steel-embedded hardened slideways on two sides to eliminate the chattering of large column under the action of intermittent alternating cutting force during the gear hobbing. The middle zero-clearance rolling block slideway guide structure improves the X-axis positioning accuracy and repeated positioning accuracy.

4. The machine is installed with full-enclosed housing and oil-mist separator to effectively handle the oil mist generated during the high-power cutting with high coolant flow.

5. The machine can be installed with special internal gear milling toolpost to expand the machining functionality.

This machine is applicable for the machining of internal and external gears in the military, wind power, ship-building, mining machinery, metallurgical machinery, hoisting machinery, and construction machinery industries.
