数控刀具技术现状和发展（Present situation and development of NC cutting tool technology） Present situation and development of NC cutting tool technology Http:// release time: 2010-08-27 source: electromechanical home In recent years, the rapid development of CNC machining technology has promoted the research and development of NC cutting tool structure, basic research and new products. The worlds major manufacturers of CNC machine tools with a knife type, size range, a huge number, often dazzling, miss the point. The relevant scientific knowledge and tools in recent years CNC tool materials, structure, and application of new products, technology status and development trend of the essentials, this article described, in order to understand the main points to grasp the information related tool of new products. I. brief description of NC tool classification Two, CNC cutting tools, new products, technology status and development trends 1, overview: In recent years, the achievements of CNC cutting tools, materials, basic research and new products are focused on High-speed (ultra high speed), hard (heat resistant, difficult to process), dry, fine (super fine) CNC machining technology. The tool material of new product development in superhard materials (diamond, surface modification of coating material, TiC base metal ceramics, cubic boron nitride, Al2O3, Si3N4, W, Co base ceramic) coatings and fine particles (particle velocity) and cemented carbide containing Go powder metallurgy high speed steel and rapid progress in the field of. 2 、 superhard material field: (brazing polycrystalline and single crystal diamond cutters) has been rapidly used in high hardness, high strength and hard machining nonferrous metal (alloy) and non-ferrous metal nonmetal composite parts of high speed and high efficiency, dry (wet) mechanical machining industry. The general situation is described as follows: Automobile and motorcycle industry: polycrystalline, artificial diamond cutter, cutter, cutter, reame
