1. Process Tube DN: 1mm to 12 mm; 2. Mass production in short time 3. Applied in hydraulic cylinder or precise tube process.

Combined Boring Head for CNC Skiving Roller Burnishing Machine

1. Processing dimension:

Inner DN40- 250mm pipe with scraping and burnishing thickness: 1mm

DN80-400mm pipe with scraping and burnishing thickness: 6mm

2. Main components:

Body of the boring head , sustainable rack , shaft , rolling cylinder, Nyon stock , pull pin, rotating pin, drogue, all kinds of springs, piston , covers or caps , all cutting blades, sustainable rack bases etc.

3. Processing procedure:

Check drawings in detail→purchasing relative material→process material on lathe→heat treatment of lathed material (Quenching , tempering and nitriding) →grinding, polishing→inspection of all parts→assembly →Anti-embroidered processing →package→delivery

4. Processing Method:

To be scraped forward and tumbled afterward, and it is capable of rapidly adjusting dimensions of cutting tools , guide blocks and tumbling mechanism respectively and the blade holder, guide block and tumbling parts can be drawn back synchronously through the control of hydraulic pressure to prevent the processed surface from cutting or damaging thus to make the whole system circulated stability and rapidly.

5. Applicant:

This scraping roll light system have special characters of easy operation, high efficiency and precision , floating refining boring, American-Style Rolling , it is very suitable to lots production of engineering hydraulic cylinder , precise processing of cold drawn or hot rolled or casted steel tubes

6. Advantage comparing with traditional tool:

It finishes the integration of the five segments and 3 workmanships such

as the rough boring , precise boring , rough scraping , precise scraping and rolling pressure to realize the one time large margin steel tube

process with great efficiency (above 20 times higher than traditional honing, ) and longer life. after process , the surface hardness improved 30%and its accuracy can reach IT80, and its roughness can arrive in Ra 0.05-0.2um.

7. Longevity influence elements:

Careful assembly, well debugging, cutting thickness , cutting speed, properly and best takes advantage of blade, burnishing volume, process lubricated oil or liquid etc.

8. Comment:

the whole set we can make it , as long as you provide combined boring head coupling parameter with the high efficiency skiving and burnishing machine or similar cnc machines
