Cutting tools and tool in this contradiction, why should highlight innovative tool grasp old saying:?. "We must first of its profits" We all know Tiger is very powerful very powerful, because it has sharp teeth ! the tool is a machine "teeth", advanced machine tools must configure the advanced tool that "teeth", in order to play its due role and power! tool is "bid", often caught tool innovation of this "bid" many weak links and key production techniques in order to be solved.      The past 20 years, as a result of CNC machine tools, CNC systems, tool material, coating technology has made significant progress, has reached a new level, coupled with constant innovation tool structure, so cutting into the high-speed cutting (High Speed Machining) a new stage its main feature is the cutting speed and feed than conventional increased by 5 to 10 times. At present, China has become a manufacturing country, but not the manufacture of power. High level of China's machinery manufacturing, processing technology level, the average labor productivity is still very low, high-precision cutting tools, etc. are also a large number of imports, the fundamental way to solve this problem is to accelerate the training of highly qualified personnel and improve innovative industry innovation development capabilities.      The tool most innovative method of universal significance, is to use the preferred method of application of the dialectical method to guide reform and the creation of learning tools. Such as the processing of different workpiece materials, machine condition, choose a different tool grades, tool geometry (see Table I, Table II), Groove, tool structure, choose a different cutting parameters, processing procedures, etc., preferred method can help us quickly find reasonable parameters to achieve an immediate effect. The creation of learning can help us find a more scientific and more rational innovative solutions. Only raise awareness of the importance of the tool, the tool to increase investment and innovation, in order to effectively improve labor productivity and economic efficiency of enterprises, foreign entrepreneurs often said:. "Dividend companies on the cutting edge."
