My current machine total about more than 400 units, but the total number of CNC machine tool is only more than 20, the rate of CNC machine tools is very low. China started late, the technology is relatively backward, there are lots of old lathe, also because of the lack of repair and maintenance of professional, the machine tool working accuracy greatly reduced. From the foreign purchase of new CNC lathe price is quite expensive, ordinary enterprises simply can not afford. In mechanical manufacturing industry, there are more than 90% mechanical parts are manufactured by machining. In the process of cutting, machine work into cutting heat equivalent, the cutting heat in addition to a small number of escapes into the surrounding medium, the rest are into the tool, chip and work piece, tool wear will accelerate the rise of cutting tool, work piece and tool temperature, caused by the thermal deformation caused by the thermal deformation of machine tools, even when serious. Therefore, in the process of cutting machine, measurement of cutting temperature is very important. In the high speed lathe, in order to improve the machining precision lathe, cutting tool in the cutting process of thermal deformation must be controlled, this just know the tool temperature is n
