Adopted with principle of generating method and CNC EGB, to achieve gear rack movement and differential compensation, Dry or wet cutting, horizontal type, YGS3612 CNC gear hobbing machine is available to precisely produce cylindrical gear, helical gear, drun gear, worm gear and spline etc.
This model is widely applied for large production of small module gears in the industries of instruments/apparatus, electric tools, motorcycle/auto, reducer motor and aeronautics/astronautics or defense military field etc.

Main Features:
1, 6 axes control, 4 axes linkage, the 6 CNC axes control are:
A axis: Hob shaft swivel
B axis: Hob spindle swivel
C axis: Table swivel
X axis: Radial feed
Y axis: Hob shift feed
Z axis: Axial feed
The 5 linkage axes are: B, C, X, Z,
2, Electronic gear box to achieve dear rack movement and differential compensation
3, Backward protection function: When interruption of power or another kind of emergency, synchronously retreat knife for protection.
4, Software for fault diagnostics and alarm show.
5, Precise cutter setting in the second cutting after hear treat in initial hobbing, up to the hardness of HRC55° ± 2° .
6, Indexing in high precision, to eliminate gap.
7, Dry or Wet cutting.
8, Maching precision to Grade 6(GB/T10095.1-2008), Roughness of teeth surface below Ra1.6μm.
