| Abstract: | The laser quenching of tubing threads is carried out. The surface of the material treated appears a superfine structure. The surface hardness of the hardened layer is 340 HV, with a depth of 0.5-1.1 mm on the top of tooth and 0.2-0.4 mm on the tooth root. With this technology, the thread gluing of tubing can be avoided. The operating principle and processing technology of the laser quenching system are introduced. Test shows that the production efficiency of the laser quenching technology can satisfy the requirement of the production line. |
