Main features:

This machine is a five-axis CNC gear hobbing machine, of which the CNC shafts are radial feeding shaft (X-axis), tangential feeding shaft (Y-axis), axial feeding shaft (Z-axis), hobbing cutter spindle rotating shaft (B-axis) and worktable rotating shaft (C-axis). This machine can be used for machining of various gears with special tooth profiles, including taper gears and drum gears, besides the cylindrical spur gears, spiral gears, short spline shafts, sprockets, and worm gears.

The standard model is installed with FANUC-0iF CNC system and is provided with common communication interfaces.

1. The motion of the AC spindle motor directly installed on the toolpost is transmitted to the hobbing cutter spindle by three high-precision cylindrical helical gear pairs to remarkably reduce the drive error, improve the drive accuracy, and enhance the related drive characteristics and drive stiffness.

2. The large-diameter high-precision cylindrical helical gear drive is applied to change the worm and worm gear drive mode of traditional worktable. The worktable is supported by high-precision high-stiffness rolling bearings, with the maximum speed up to 300rpm, to remarkably promote the machining accuracy and efficiency of the machine.

3. The main guiderail pairs adopt rectangular large-plane guiderails with injection molded movement faces and the ball screw drive is applied to ensure good drive stiffness, high support capacity, and high motion linearity.

4. This machine can be installed with double-station switching manipulator and material bin to realize the automatic loading and unloading of workpieces.
