Precision Coating Of Thread Solid Carbide End Mill

In order to reduce tool wear, prolong tool life and increase cutting speed, a few microns high hardness and high wear resistant Refractory Ti-Al-X-N coating was deposited on the surface of high strength tool by vapor deposition method.

The core technology of bearing tool: machine tool is called "the machine that makes the machine" . If high-end CNC machine tools are the works of art of modern industrial civilization, then thread solid carbide end mills are works of art on the diamond, and the diamond light from the surface of the knife a few microns thick precision coating.

Thread solid carbide end mill with thread has the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat resistance, oxidation resistance, low friction coefficient and low thermal conductivity. The reason is that the coating material, as a chemical barrier and thermal barrier, reduces the diffusion and chemical reaction between the tool and the workpiece, so that the tool wear is reduced, the tool life is increased more than 3 times, and the cutting speed is increased by 20% and 100% . It can be said that the thin coating carries the core technology of the tool.

At present, the proportion of coated tools in cutting tools has reached 80% . Due to the monopoly position of foreign enterprises in the field of high-end cutting tools, in the special projects of CNC machine tools in our country, the thread solid carbide end mills with thread and its core coating technology has been paid more and more attention, breakthroughs in coating technology have also been incorporated into a number of topics.
