How to make a simple metal lathe by yourself

Quenching of machine tool guide rail is a kind of metal heat treatment process, which heats the guide rail to a proper temperature and keeps it for a period of time, and then immerses it in quenching medium for rapid cooling.

Commonly used quenching media are salt water, water, mineral oil, air, etc. Use more water. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, measuring tools and parts (such as gears, rollers, carburized parts, etc.). ) requires surface wear resistance. By quenching and tempering at different temperatures, the strength, toughness and fatigue strength of metals can be greatly improved to meet different application requirements. Quenching of machine tool guide rail greatly improves the service life, wear resistance and anti-damage hardness of machine tool guide rail, thus improving the production efficiency of machine tool to a certain extent.
