CNC Gear Hobbing Machine

Main Features

1. The machine tool is 7 axis with 4 linkage, seven CNC axis consist of:

1. Spiral angle automatic positioning swing axle

2. Rotary motion of hob spindle

3. Rotary motion of headstock spindle(rotation of work piece)

   X- Axial feed motion

   Y- Radial feed motion

   Z-Tangential feed motion(channeling cutter movement)

   W-The tailstock automatic top tight

   Four couple axis: B axis, C axis , X axis, Z axis;

1. Auto loading/uploading

2. Applies electronic gear box(EGB) to realize sub-teeth and differential compensating motions;

3. Rewind protection function: in the event of power failure or a fault occurs, press the emergency stop, synchronously rewind the cutter back-off, so as to avoid destroying the cutter and safe guard the machine tool;

4. With fault diagnosis and alarm display functions;

5. With secondary cutting and auto tool presetting function: after roughening burning hot treatment of gears, secondary processing on the hardened tooth surface with the precision processing hardness HRC 55±2°；

6. The headstock applies high-precision gear pair to fulfill high-speed and high-precision graduation, and is provided with backlash eliminator;

7. With dry/wet cutting funtions, capable of high-speed dry type cutting;

8. The processing precision can reach class 6 in GB/T 10095.1-2008,and the roughness of gear surface is Ra1.6.

9.
