CNC Gear Hobbing Machine
- Product description: CNC Gear Hobbing Machine
PRODUCT INTRODUCTION
Main Features
-
The machine tool is 7 axis with 4 linkage, seven CNC axis consist of:
-
Spiral angle automatic positioning swing axle
-
Rotary motion of hob spindle
-
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;
-
Auto loading/uploading
-
Applies electronic gear box(EGB) to realize sub-teeth and differential compensating motions;
-
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;
-
With fault diagnosis and alarm display functions;
-
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°;
-
The headstock applies high-precision gear pair to fulfill high-speed and high-precision graduation, and is provided with backlash eliminator;
-
With dry/wet cutting funtions, capable of high-speed dry type cutting;
-
The processing precision can reach class 6 in GB/T 10095.1-2008,and the roughness of gear surface is Ra1.6.
