The ball screw is an important part of the machine tool. It is a transmission and positioning functional component that converts rotary motion into linear motion or converts linear motion into rotary motion. Its main function is to ensure the accuracy and uniformity of linear motion. During the operation of the machine tool, the ball screw is subjected to huge friction. Therefore, ball screws are usually required to have high hardness, wear resistance and service life in production. In order to meet the above requirements, many manufacturers use high-frequency induction hardening machines to quench and heat-treat ball screws.
In the past, people mostly used coal furnaces, gas furnaces, etc. to quench and heat-treat ball screws. However, the quenching effect was always unsatisfactory, and defects such as cracks and deformation often appeared, which greatly affected the normal use of ball screws and caused Bigger waste. With the improvement of production technology, high-frequency induction hardening machine with IGBT module as the core is available. This equipment has been loved by many heat treatment manufacturers as soon as it came out, and it has also become a must-have equipment for ball screw quenching.。
The high-frequency induction hardening machine is highly efficient and energy-saving, and the heating is easy to control. The heating current value and heating voltage value can be set, and the current, voltage, power and frequency are all displayed. The operation is intuitive, simple and convenient. After quenching by this equipment, there will be a hardened layer on the surface of the ball screw, about 2.5mm. It is this layer of hardened layer that greatly improves the wear resistance of the ball screw and meets the needs of the work.
