In the domestic induction heating and heat treatment industry, due to the characteristics of fully automatic, convenient operation, variety of quenching and precise control, quenching machine tool occupies an important position. At present, the quenching machine has been widely used in the domestic large-scale machinery manufacturing, automobile manufacturing, construction, metallurgy and other industries.
The quenching machine has vertical and horizontal quenching machine. It is mainly applied to the induction hardening of metal workpieces, such as shaft, gear, pin, plate and so on. Most of the transmission system of quenching machine adopts mechanical transmission, ball screw transmission and linear guide transmission are the most commonly used, realizing full automation of transmission. Moreover, quenching machine tool has achieved CNC numerical control operation, the configuration of PLC control system, can control the movement of the machining speed and location, even in the middle of variable speed, can meet the needs of the processing to the greatest extent. In addition, the quenching method of quenching machine includes continuous scanning quenching, piecewise continuous scanning quenching, and quenching at the same time, which is more efficient.
