What guarantees the machining accuracy of machine tools?

2、 Practical application

1. Full closed loop control system

The thermal performance (thermal deformation) of position detection device is generally non-metallic material. The coefficient of thermal expansion is not consistent with each part of the machine tool. It is the key link of the working accuracy of the machine tool. Therefore, it is necessary to solve the heating problem in the machining process of the machine tool to overcome the thermal deformation caused by temperature. High end machine tools will adopt various methods, such as hollow screw cooling, guide rail lubrication, cutting fluid constant temperature cooling and other ways to reduce the thermal deformation during machining..
