introduction: Under the influence of internal and external heat sources,The parts of the machine tool will have different degrees of thermal deformation,The relative motion relationship between the workpiece and the tool is broken,Also a quarterly decline in machine tools。For CNC machine tools,Because the whole process is controlled by computational instructions,The influence of thermal deformation is even more serious。To reduce thermal deformation,The following measures are usually adopted in the structure of CNC machine tools。 1.Reduce fever The main heat source of thermal deformation occurs when the machine is heated inside,The heat source should be separated from the main engine as much as possible。 2.Controlled temperature rise After taking one
