According to the different styles placed when processing workpieces, there are quenching machine tools and horizontal quenching machine tools. Equipment must have more than two people before starting operation, and specify the person in charge of operation. General situation of base guide rail in machine tool industry hardening and quenching, thermal treatment of inner wall of building pump pipe; . The lifting of the machine tool adopts the tight ball screw, and the transmission is stable. Workbench system: The stepping motor is used to drive the ball screw through the process variable speed mechanism to realize the lifting behavior of the upper worktable, with stepless adjustable moving speed, light transmission, high guiding precision and accurate positioning. Igbt is used as the primary component, which saves more than 30% of electricity compared with the old high frequency. There are mechanical and hydraulic transmission modes; There are plc, touch screen, cnc and other control systems, which are mainly used for quenching, and can also be used for annealing or welding processes. According to the different styles placed when processing workpieces, there are quenching machine tools and horizontal quenching machine tools. Quenching hardness and hardness layer are moderate; C. high quenching efficiency: the double track can be quenched by 200 ~ 400 mm per minute; If the guide surface is too wide, the inductor can be quenched on one side, and if the guide surface is narrow, it can be quenched on both sides at one time. For example, if a metal cylinder is placed in an induction coil with alternating medium-frequency current, the metal cylinder is not in direct contact with the induction coil, and the temperature of the electrified coil itself is already very low, but the cylinder is heated to redness or even melting, and the redness and melting speed can be realized only by adjusting the frequency and the strength of the current. Welding of straight bit and plum blossom bit for prospecting. Ultrasonic flaw detection shall be carried out on the workpieces one by one. Any workpiece with defects such as white spots, serious segregation and looseness after flaw detection shall not be heated by high-frequency equipment.
