宝山钢铁总厂无缝钢管厂由德国引进了8台数控管体车丝机。自1986年负荷试车以来,这些车丝机在加工螺纹的过程中,一直不能自动断屑,油管、套管的产量和质量受到很大的影响,供方对此问题也无力解决。在大连理工大学的配合下,该厂开展了攻关活动,经过反复试验和现场实战,解决了数控管体车丝机的断屑问题,其主要方法是:有效控制现有刀片
Baoshan Iron and Steel Plant Seamless Steel Tube Plant by the German introduction of eight CNC pipe body machine. Since the test load in 1986, these threading machines have not been able to break chips automatically during the process of thread processing. The yield and quality of tubing and casing are greatly affected, and the supplier can not solve this problem either. In cooperation with Dalian University of Technology, the plant carried out research activities, after repeated tests and field combat to solve the CNC pipe body machine chip breaking problem, the main method is: Effective control of the existing blade
