During the cutting process, the cutting fluid has the functions of cooling, lubrication, cleaning, chip removal, rust prevention and the like, but some materials cannot be added with the cutting fluid because of the special property of the materials, and dry cutting processes, such as carbon fiber materials, are required. The unavoidable problem in the process of dry cutting is that the mechanical property of the cutting tool is reduced due to the fact that the temperature of the turning tool is increased, and the turning tool is rapidly worn to influence smooth completion of turning.
In order to reduce the cutting temperature of the turning tool in the dry cutting process, the internal cooling technology of the tool can be adopted, so that cooling liquid circulates in the turning tool, and heat generated during turning of the turning tool is taken away by the circulating liquid, thereby reducing the cutting temperature and improving the service life and the processing quality of the tool. As chinese patent CN205414443U discloses a separate internal cooling turning tool comprising: blade, blade seat, circular sealing washer, dysmorphism sealing washer.
