Global rise in raw material and the number of competitors increasing globalization, with high quality products, excellent service to create value for the customer become the key to competition, therefore, the cutting tool manufacturers are also actively for their own development as well as to the progress of the whole industry to seek a better way. From some of the world's leading cutting tool material distribution can be seen, the high speed steel accounted for 35%, carbide accounted for 15%. Now the main production of tungsten in the Alps, the Himalayas and the Pacific rim. China has 60% of the tungsten, hidden in the international market because of the shortage of raw materials, the price of APT in recent several years from $50 per ton to about $250 a tonne. And the cost increase will be passed on to tool the end user. 

    Current related research institutions in the world for such situation, the ongoing positive research, the main research plan is as much as possible in order to reduce the amount of tungsten in the cutting tool, the main method is only used in a key part of the tool or design special tungsten cutting tool geometry can be seen from the cutting tool industry statistics, the proportion of carbide in the future will gradually increase. And the ratio of high speed steel products will gradually decrease. Japan's tool association statistics show that China has become the world's largest machine tool consumer, followed by Japan and the United States, Italy, etc. Rapid economic growth in Asia, according to the statistical data of the Asian development bank, China's GDP growth in 2007 is about 10%, about 8% in India. Metal processing industry in a good economic environment, Japan also sustained high growth in recent years, from the point of cutting tool production, production of carbide cutting tools in recent years continue to grow, showed a trend of decline the start of HSS cutting tools, carbide were significantly increase in exports, the main export to Asia, followed by Europe, then in North America and other regions. High speed machining is generally considered to increase production, reduce the manufacturing cost of processing technology. Dry processing or the concept of minimal quantities of lubricant is now processing industry to reduce the environmental protection and the main goal of the production cost. For cutting tool manufacturer and coating suppliers, the most important thing is productivity. Cutting performance, cutting speed, cutting quantity per unit time) increased by 20%, the manufacturing cost will be reduced by 15%. More and more strict processing requirements need further development, cutting tool material and coating to improve processing conditions and improve the tool design. Is facing the challenges and to improve mainly include: mechanical and structural characteristics: hardness, strength and wear resistance; Heat and chemical properties, heat resistance, insulation, catalytic; Biology: adaptability, insecticidal properties; Electronic and optical properties: reflective, transparency, etc. In recent years, the (Ti, Al) coating cemented carbide cutting tools in high-performance tool has occupied a dominant position in the market. In some special applications of high demand to promote the development of the special coating or accurate.   Nano "shorty" derived from the Greek, 1 nm is equal to 10 to the minus 9 meters, nanotechnology refers to the design, production to the structure of the material shape and size control in nanoscale devices and systems, its scope in the range of 0.1 ~ 100 nm. Nanotechnology is important mainly has two reasons, one is the surface/volume ratio has the unique surface characteristic advantage; Second, the quantum effect.

    The main form of nano materials and nano structure materials are: atomic clusters, nanoparticles, nano layer, nano fiber; Multi-layer (the thickness of the layers in the art level range). Nanostructure coating or nano coating; Nano structure of granular materials. Nanoscale coating: coating at least one size (such as grain or independent layer) is less than 100 nm. Nano coating layer than traditional coarse grains has a lower wear rate, higher hardness and strength, small particle size changed, the fracture form and the material removal mechanisms of coating, but the key problem is keep the size of the particles under heat stress. Nano composite coating containing at least two phase (crystal phase and amorphous phase) or two crystalline state. Size, volume and the distribution of the nano grain size and the thickness of the amorphous phase need optimization, in order to find the balance point between the hardness and strength, thermal stability need to be considered, and later stages in the process of coating showed mixed, decomposition of a turning point, and segregation phenomenon. Nanometer multilayer structure is composed of different materials, nano layer alternate, anisotropic characteristics, strengthen the performance of the single layer coating, by alternating layers of different auxiliary to each other, improves the coating properties. Optimistic estimates, in the next 7 ~ 8 years nanotechnology creates value will reach $3 billion, even pessimistic estimate of $1 billion. SGS hard alloy cutter
