Main features:

This machine is a five-axis CNC gear hobbing machine, of which the five 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.

This machine features following characteristics:

1. The main motion is transmitted from the AC spindle motor on the toolpost to the hobbing cutter spindle by three pairs of high-precision cylindrical gears, with the spindle motor power at 15kw. A tooth difference anti-backlash mechanism is installed on the end gear pair of cutter spindle and the multi-head hobbing cutter can be used for high feeding rate hobbing.

2. To meet the needs of different machining objects, this machine offers three structure types of worktable at the user’s choice: Standard worktable (Maximum speed at 30RPM), rotating bearing worktable (Maximum speed at 60RPM), and direct drive motor worktable (Maximum speed at 120RPM).

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. The new connection structure between balance cylinder on the column and the chain is applied for Z-axis motion to reduce the overall height of machine and better balance the vertical motion of toolpost slide.

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