The major scientific and technological project of Zhuzhou Diamond Cutting Tool Co., Ltd. - "High-efficiency precision indexable tool series and super-hard tool" was supported by the tax reduction and exemption policy for imported equipment. It is understood that the tax exemption will directly save the company 3.4 million tariffs, which is the first major technology project in Hunan Province that has enjoyed tariff reduction and exemption for two years. The high-precision and precision indexable tool series and super-hard tool products are widely used and widely used. The key technologies and public relations contents involved in the differential application fields will be different: the indexable insert base material and coating requirements of the mechanical inserting machine. Blade geometry parameters, blade clamping methods, overall tool structure design, etc. will have great differences, technical difficulties, and more research content. Hard cutting, ultra-precision cutting and new material cutting including composite materials further promote the demand and development of mechanically inserted superhard tools. Composite machine tools still have a big gap in the development and production of high-quality super-hard tool materials. Even if the insertion machine is a domestic super-hard tool, the super-hard blade (PCD CBN) material used is mostly imported from GE and DeBeers. Zhuzhou has the largest production scale, the strongest strength and the highest overall level. It has a CNC indexable insert production line that is said to have reached the world-class level. In addition, there are research centers established in recent years, including design development, use technology research and materials. Performance test and cutting experimental equipment have a good development platform to encourage the development of new industries such as environmental protection, science and education, major technical equipment, etc. The state has adjusted the import tax policy for related industrial equipment. According to the statistics of relevant departments, in 2011, Zhuzhou Customs reviewed and approved 428 batches of tax exemption and exemption, and the tax reduction and exemption was 583 million yuan, a year-on-year increase of 3 times and 14.6 times respectively. Among them, the import of major technical equipment is tax-free by 300 million yuan.
