With the increasingly fierce market competition, general machinery processing industry profits increasingly thin. Although the positive value of the CNC tool to bring far more than the added cost to this end, with careful planning started private enterprises, still want to consume the least for maximum benefits. Meet the processing requirements under the premise, try to choose low-cost tool. Domestic CNC tool late start, there are some gaps in the high-tech and manufacturing process, but on the whole there is a clear advantage: the price is reasonable; timely delivery; users can face to face with the tool manufacturer to exchange experiences, to discuss the case of tool use in accordance with their intentions custom non-standard tools, etc., these advantages are the focus of the enterprise; puzzles and solutions to. Based precision CNC machine tools to cut, the blank margin is very small, it is impossible to put the feed rate is too fast, the main way to increase productivity is high-speed cutting, this is precisely the strengths of some of coated tools. Chengdu 1000 wood, Zhuzhou Diamond, Xiamen Golden Egret and some excellent quality made knives, has experienced ups and downs, the market share has been greatly improved, in order to stabilize the cutting to win customers. In order to meet user requirements of different industries, manufacturers are racing to provide quality tools and support services. Compared with the Hills, high mountains, Kennametal, Iscar and other foreign brands, the most important feature of domestic knives are cost-effective, practical, good service, representing the industry with advanced cutting technology and manufacturing processes. The tool has a good domestic market and development space in the small and medium enterprises in the field of metal processing, more and more users with local tool manufacturers carry out technical exchanges and cooperation projects, access to relevant tools and solutions in new product development and manufacturing process technical support.
