Tool coating technology is to promote the advancement of key technologies machining , coating materials are currently modified TiN, TiCN , etc. Computer control PVD, CVD coating technology , the above coating material for mills, reamers, drills , composite tool and indexable inserts and other surface modification coating process in order to meet the high-speed cutting and long life processing of high strength, high hardness material job requirements . Tool surface using PVD, CVD coating can improve the CNC cutting tools in magnitude , expanding range of processing tools . The exhibition shows the PVD, CVD coating technology level of development and significant progress made. Compared with the rapid development of coating technology, the development of the tool material is relatively slow. But still reflects the progress made in the promotion of a high-performance tool material, tool material performance improvement achieved . Tool again shows the superior performance of ultrafine particles momentum carbide materials in the production of indexable inserts and small size drill , end mills , taps and other aspects of CNC tool and widely used conventional tools . CNC tool materials and coating technology is a new field of scientific research , the listing of each new product will be driven processing technology has leapt to a new level. Foreign tool manufacturers in the exhibition showcasing new products and new technologies , reflecting the huge demand for CNC tool market of high-tech . At the same time , faced with the rapid development of China's manufacturing industry and the demand for high quality CNC tool we have to do is speed up the development pace , updating the concept of service , improve innovation capabilities.
