Main features:

This YX3150CNC machine is a six-axis CNC high-efficiency gear hobbing machine, of which the CNC shafts are radial feeding shaft (X-axis), tangential feeding shaft (Y-axis), axial feeding shaft (Z-axis), toolpost angle rotating shaft (A-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 axial modifications, including small 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 toolpost spindle motor installed on the toolpost is transmitted to the hobbing cutter spindle by three high-precision gear pairs and a tooth difference anti-backlash mechanism is installed on the end gear pair to remarkably reduce the drive error, improve the drive accuracy and stability, and enhance the related drive characteristics and drive stiffness. The multi-head hobbing cutter can be used for high feed hobbing, with the spindle motor power at 15kw.

2. The worktable is applied with high-precision double-lead worm gear drive and is designed with damping mechanism. The spindle unloading cylinder is installed beneath the worktable to reduce the load of C-axis motor and prolong the life of worktable circular slideways.

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. 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.

5. This machine can be installed with auxiliary loading/unloading device for disc and shaft parts, depending on the user’s needs.
