- High precision Hydraulic cold drawing machine set
- Strong excircle honing machine
- Strong inner hole horizontal honing machine
- Large scale deep hole drawing ,broaching and boring machine
- High precision cyclone scraping and burnishing machine
The scraping and burnishing machine is the device to process inner
diameter of hydraulic cylinder. Compared with original honing
style,it can largely rise up quality and efficiency
Advantages of scraping and burnishing machine
In the field of production it can increase efficiency over ten
times if compared with that of honing process so it can larger
reduce cost and rise up quality of products.
The fineness of inner diameter of cylinder can reach Ra=0.08~0.02 ㎛
therefore processing quality is excellent.
It can greatly reduce wearing of the piston of the hydraulic
cylinder and prolong service life of hydraulic cylinder.
Particularly it can process inner diameter of the hydraulic
cylinder with high precision to reach the requirement of tolerance
over IT8 class while the surface hardness processed by hydraulic
inner diameter can increase over 50% if compared with processing in
honing style .
