Theory Assay and Optimum Devise of Knife Shaft on Circumvolve Lock Set Kit

According to the results of the research work, which is focused on function and structure of knife shaft, the key part of it is called circumvolve lock set kit. Based on machine control theory and control system model, this article demonstrate that the malfunction of circumvolve lock set kit caused the malfunction of auto - slewing knife shaft. Optimize the theory and capacity of it work. . Therefore, new circumvolve lock set kit is produced and taken the place of the old one. After this procedure the function and the precision is restituted. Meanwhile, the fixed system ensure the stability of high precision screw thread process of tube in Baosteel Steel-tube Corporation.
