In recent years , the results of basic research and new product focus CNC tool materials used in high-speed ( Ultra High Speed ​​) , hard ( including heat and difficult to process ) , dry , fine ( ultra fine ) CNC machine technology field processing. New product development tool material superhard material ( diamond, the surface modification coating material , TiC cermet base class , cubic boron nitride , Al2O3, Si3N4 ceramic- yl ), W, Co and the like, coating of fine particles ( ultra fine particles ) cemented carbide substrate and containing Go classes , such as progress in the field of powder metallurgy high speed steel faster .     Field of superhard materials :     Diamond ( PCD brazed single crystal ) has quickly applied to all kinds of tools with high hardness , high strength, difficult to process non-ferrous metals ( alloys ) and non-ferrous metals - non-metallic composite parts , high-speed , high efficiency, dry ( wet ) type mechanical machining industry. Their profiles are as follows:     Automobile and motorcycle industry : polycrystalline, monocrystalline synthetic diamond face milling , boring tools , turning tools , reamers , composite (combined ) hole machining , CNC tools, etc. are widely used in high- strength, high hardness Si - Al alloy Auto parts production line ;     Bamboo flooring , furniture industry : polycrystalline , CVD diamond thick film deposition ( PDC ) cutter, three-blade shaped cutter, face milling tools are widely used in other types of high hardness composite wood flooring, furniture , windows and doors ... other parts of the automatic production line ;     Aviation, aerospace , automotive and electronics and information technology industry : CVD diamond film coating CNC tool ( carbide overall WCo class -based ) and more used in milling, turning , drilling, reaming and cutting machining of high -strength aluminum alloy countersink ( casting, forging ) , fiber - metal laminates , carbon fiber thermoplastic composites, alloys, graphite, ceramics ... and other components meet the high-speed , high life, technical requirements for dry machining . Manufacturers are constantly improving the diamond coating technology to improve the fastness and the density of the diamond film and the tool substrate ;     Processing technology in the field of fine ( ultra fine) machine : monocrystalline natural, artificial diamond tools used in a variety of precision instruments lens , fine mirrors , computer disks , photocopiers ( VCR ) drum ... other parts of the ( ultra-fine , nano ) Turning processing ;     Single-crystal diamond tool is also used in ophthalmology corneal surgery fine cutting and printing plate making fine engraving ... industry.     Manufacturers are improving all kinds of diamond grinding tool technology, precision grinding and grinding efficiency.
