In the machinery industry, shaft parts with a length-to-diameter ratio greater than 25, that is, L/D>25, are called slender shafts. It is generally believed that the larger the value of L/D, the easier it is to deform during turning, so How to avoid the deformation of the slender shaft is a major difficulty in the heat treatment process. Our company has many years of experience in heat treatment, and has designed and developed high-frequency induction hardening machines and CNC hardening machine tools for slender shafts, which can maximize the quality of quenched parts and reduce deformation.
The high-frequency induction hardening machine is a new type of equipment that uses induction heating to heat and heat-treat the metal surface. The inductor is the most important and the most direct contact with the workpiece. The sensor is mainly made of brass or copper tubes, which can be divided into single-turn and multi-turn, with or without holes. The sensor with holes can spray water to cool while heating.
The output power of the high-frequency induction hardening machine ranges from 30kw to 160kw. The higher the output power, the stronger the heating capacity of the machine. The power directly affects the heatable diameter of the workpiece. The frequency determines the quenching depth. The higher the frequency, the shallower the quenching layer. vice versa. For the quenching requirements of shaft workpieces, we also design a special CNC quenching machine tool, which can realize continuous quenching, scanning quenching, segmental continuous quenching, rotary scanning quenching, etc. of shaft parts, with good process repeatability and small error.
