Main Features

Advantages compared with traditional honing
1) Improve processing efficiency: Processing speed is nearly 20 times that of honing.
2) Enhance surface hardness: Surface hardness is increased by more than 50%.
3) Processing precision: Processing precision can reach level IT8, and surface roughness can reach Ra0.05-0.4μm.
4) Working environment: Low noise, non-pollution, labor cost-saving.
5) Reasonable processing arrangement: Skiving & roller burnishing can be arranged as the last operation after the others (such as drilling oil filler hole, welding, threading). 

Machine Parts

Name: Bliwing Cylinder 

Clamping base: clamp male cone of the work piece by  moving the hydraulic cylinder against the locating base, to  have the work piece fixed. 

Headstock

Ensure large torque at low speed and constant power output at high speed by adopting ZF gear two-speed transmission box made in Germany. Imported precision bearing is adopted for the main shaft, to ensure its stiffness and precision. 

Locating base:

a new locating base locking device is adopted to fix the locating base at the desired place.

Work piece supports:

 there are two work piece supports. With a V structure, each of them can be adjusted freely according to outer diameter center of the work piece. For they are installed on the guide rail slide, it is convenient and easy to push them.
