The function of CNC lathe guide rail quenching

The machine tool guide rail is an important part of the machine tool to move freely. The continuous movement of the machine tool determines that the machine tool guide rail must have sufficient hardness and will not be easily damaged. Therefore, the quenching of the machine tool guide rail is inevitable. The guide rail is quenched to improve its own hardness, thus ensuring the machine tool of normal operation.

The machine tool guide rail is quenched, and the guide rail is heated to an appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling of the metal heat treatment process. Commonly used quenching media are brine, water, mineral oil, air, etc., and more water is used. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, measuring tools and parts that require wear-resistant surfaces (such as gears, rolls, carburized parts, etc.). Through the combination of quenching and tempering at different temperatures, the strength, toughness and fatigue strength of the metal can be greatly improved to meet different application requirements. The quenching of the machine tool guide rail greatly improves the service life, wear resistance and damage resistance hardness of the machine tool guide rail, thereby improving the production efficiency of the machine tool to a certain extent.

Technical indicators

1. The depth of the quenching layer of the guide rail is generally 1.5-3mm, and the hardness is HRC45-52;

2. The quenching deformation of the guide rail is less than 0.06mm;

3. The heating speed should be fast, 200-400mm/mim.
