The cutting roller is essentially a specially treated high precision seamless steel tube. The final finish of the inner hole of the hydraulic pressure cylinder is honing or cutting.
1, our company cutting: (1) the basic process of rolling pipe material are all made of the production of TPCO tianjin big seamless continuous rolling pipe, (2) tube material inspection, pickling, phosphating, saponification (3) cold drawing processing form Cold Drawn Tube (4) the cold drawn our SRB2560 type cylinder horizontal hole cutting CNC boring roller mill.
The scraping tool is a composite machining tool that can be continuously used for shaving machining (hole cutting machining) and rolling processing.
1 way
In advance, the processing of scraping and rolling is done, and then the processing is finished quickly.
When using 1WAY, it can be processed and rolled in the same process, so that the processing time can be shortened. The processing condition is the condition that must satisfy the scraping processing or rolling.
2 way
In advance, the grinding process is carried out and the rolling process is carried out to complete the processing.
When using the 2WAY way, the process of scraping and rolling is separated, so it can be processed with the best processing conditions. But you can't get out fast.
The company adopts the second processing mode.
Compared with honing steel pipe, the cutting roller has many advantages:
(1) the efficiency of work is greatly improved, which is several times the efficiency of the Honing Tube to more than 10 times.
(2) improve the precision of the product, the computer operation, the precision of the hole in each steel tube, and the difference between 5-6 meters long and 2-3 wire.
(3) increase the strength of the surface of the product.
