Machine tools are the main machines for forming and processing metal materials, and are the most widely used and important machines in industrial production. According to the shape and precision of the processed parts, the size of the batch, the particularity of the parts, the general or special purpose and the degree of automation, the machine tools can be divided into various machine tools, usually lathes, drilling machines, boring machines, grinding machines, milling machines, planer slotting machines, broaching machines , special processing machine tools, etc. There are many parts in the machine tool (bed, guide rail, lead screw, gear, worm, turbine, sleeve, bearing, etc.), with complex shape, high precision requirements and long service life. Today, we mainly talk about the quenching of guide rails.
The guide rail is an important part of the machine tool. There are guide rails on the bed, column, beam and turntable of the machine tool. Common materials for machine tool guides are cast iron and hardened steel. Surface quenching the guide rail to strengthen its surface can improve the wear resistance and service life of the guide rail. The quenching methods of the surface of the cast iron guide rail include high-frequency induction quenching, super-frequency induction quenching, and medium-frequency induction quenching. The depth of the surface hardening layer of high frequency induction hardening is 1-1.5mm, the depth of ultrasonic induction hardening is 1.5-2.0mm, and the depth of medium frequency induction hardening is 2-4mm. The advantages of induction quenching are uniform quenching hardness, consistent quenching depth, high productivity, suitable for mass production, and are currently widely used at home and abroad. The integrated guide rail CNC quenching machine tool produced by our company, coupled with the exquisite quenching sensor, greatly improves the guide rail quenching quality of domestic and foreign customers.
