The accuracy of the machine tool rail has a great influence on the accuracy of the entire machine tool. It must be prevented from deformation and wear, so machine tool guides are usually made of gray cast iron, such as HT200 and HT350. Gray cast iron has better wear resistance under lubricating conditions, but has poor resistance to abrasive wear. In order to improve the wear resistance, the surface of the guide rail can be quenched.
