Main features:

This machine is a ten-axis CNC dry gear hobbing machine. The double-channel two-station of the machine are working simultaneously. The gear hobbing station incorporates three CNC linear shafts: radial feeding shaft (X-axis), axial feeding shaft (Z-axis), tangential motion shaft (Y-axis). Three CNC rotating shafts: Worktable rotating shaft (C-axis), hobbing cutter spindle rotating shaft (B-axis), and toolpost rotating shaft (A-axis).

This machine is installed with standard FANUC 0i-F CNC system to realize four-axis linkage control. The chamfering station incorporates workbench rotating shaft (C1-axis), chamfering cutter feeding shaft (Y1-axis), and deburring cutter feeding shaft (Y2-axis). The automatic loading and unloading of workpiece are realized by the manipulator rotating shaft (C2-axis).

1. The machine incorporates the chamfering station and four-station switchover manipulator to realize the hobbing and chamfering functions of the gears.

2. All shafts are directly controlled by independent AC servo motors, featuring short drive chain, good drive stiffness, and high drive accuracy. The worktable rotating spindle (C-axis) and the hobbing cutter rotating spindle (B-axis) are directly driven by built-in spindle motors to realize zero-clearance drive and remarkably improve the drive stiffness and dynamic response speed of spindle.

3. The hobbing cutter spindle (B-axis) can realize stepless speed change within the range of 1~2,000RPM, which is especially suitable for the high-speed high-efficiency dry-type gear hobbing with multi-head hobbing cutter.

4. All slideway pairs adopt the high-precision high-stiffness linear roller slideways, featuring good drive stiffness, high carrying capacity, and high motion linearity.

5. This machine can be installed with automatic tooth alignment device to realize the hobbing function for hard tooth faces.
