In recent years, automotive tool has been along the "three high and one special" way forward in the continuous innovation, progress, and has not stopped, it is undoubtedly the most gratifying. Especially in the "high efficiency" has made great progress, compared with the original, the processing efficiency is improved by more than 25%. In the tool material, hard alloy will maintain steady growth, high speed steel market share further reduced, and super hard material with the change of the workpiece material gain, but is not growing too big, occupies the mainstream status in quite long period of time is still hard alloy cutter.

Auto tools in the "three high and one special" (high efficiency, high precision, high reliability and specialization) on change, is developed with the rapid development of automobile manufacturing. Automobile production program of continuous improvement, processing time increases, the speeding up the development of new technology in tool manufacturing industry, tool consumption goods into high added value, high technology content of products from low value. Progress of tool materials, tool coating, tool structure, cutting parameters such as crystallization, belong to the modern science and technology. The development of new cutting tool materials, coating, cutting tool structure and digital manufacturing technology, has been applied in actual production. Cutting speed can reach 4000m/min, spindle speed of 15000~20000r/min is a common parameter; the composite multilayer, gradient structure, nano structure in the development of coating technology, accelerate the use and promotion of actual production; new development tool assisted, to shorten the process to meet the processing and adjusting time bring security, such as Mapal the quick change of HFS10 cutter bar application; CNC machining center tool change time and so on are "three high positive changes in a special".

It should be said that the processing tool for dies of automobile covering parts of many changes in the past ten years, is a multi species, either on the scale of the cutting tool manufacturers are according to the different needs of customers were refined, and as far as possible to provide alternatives more, according to the different processing environments are more choice; two is the quality a lot of progress, particularly in the service life and precision machining tool; three is the tool prices are also rising.

At present, especially for the saloon car is more and more to join our common home, with the domestic automobile manufacturers more and more quickly. The automobile production base set up and transfer to Chinese, becomes in the tool vehicle powertrain applications more widely. Its own characteristics and development in the future pay more and more attentions. With the powertrain manufacturing tend to lightweight, simple structure, high performance, powertrain manufacturing technology and process has undergone great changes, high speed, high efficiency, flexibility is the main characteristics of the manufacturing process, which is also consistent with the production requirements of modern automobile industry many varieties, small batch. As the powertrain is the crucial part of manufacturing technology, now the car power mainstream application assembly tool features are also increasingly reflects the production requirements of the modern automobile industry, the concrete manifestation is: from the powertrain requirements, high quality, high stability, high efficiency; from technology, high speed, the composite, specialization, standardization, multi species, heavy. The automobile industry is the future development of advanced cutting mode, cutting tool integrated tool environment, tool outsourcing management etc..

As one of the typical user, automotive tool I think, now the tool is more and more close to user needs. Fully extended special cutter tool for processing new material, some typical process.

1) for example, aluminum cylinder head valve guide hole quality, we use the diamond material reamer machining, tool life can reach 30000, the processed surface finish. The practical application of the diamond material tool, reducing the frequency of grinding tool, tool disassembly, assembly, replacement frequency. At the same time, rotating speed, high cutting speed, short processing time, reflects the "tool of high efficiency and high stability".

2) another example, aluminum engine cylinder cover mounting screw hole, we adopted the extrusion Taps for processing, the processing method of threaded hole assembly, has good wear-resistance, high. The processing of the former process that requires high processing quality of bottom hole, we adopted the reamer reaming holes. This reflects the tool "of high stability, high precision".

3) strong professional performance tool. A special tool, can complete the same position, one-time processing multi stepped hole, asymmetric shape, which greatly reduces the process, avoiding the additional equipment, personnel waste.

In recent years, China's industrial development Carbide made no small achievement, but compared with developed countries, there is still not a small gap.

Less R & D investment, innovation ability is poor. China Cemented Carbide Industry, still do not have a high level of research and development institutions, as well as the gap between funding and management talent, high-end product development capability is weak, it is difficult to produce its own property and original achievements, technological upgrading of enterprises and therefore difficult to obtain strong technical support. It is understood that the Swedish company Sandvik Coromant plant, R & D investment in 2000 was 550 million kronor, equivalent to Zhuzhou Cemented Carbide plant in nearly 30 years the total R & D investment is not the mouth.

Equipped with low-grade, large gaps: applied research, development and production of high-grade carbide special equipment is mainly dependent on imports, a large gap between domestic equipment, due to financial and other reasons, have the ability to purchase imported equipment manufacturers rarely is the application of advanced domestic manufacturers The number of devices is very limited, to the development and production has caused great difficulties.

Alloy production out of touch with the tools of production: Foreign manufacturers also often carbide tool production companies, is very conducive to the development of carbide tools. Because of historical reasons, the production of carbide and tools belonging to two metallurgical and mechanical systems management, resulting in the production of cemented carbide tool production and long divorced, has developed high-grade carbide tool issues yet to be resolved.

Lower industrial economies: Due to the above reasons, although our Carbide industrial scale, but few high-value-added products, the amount of high-end products like high-performance alloys, coated abrasive products, special shaped products, precision carbide tools, etc. less and the quality is not high, due to the high value-added products worth several times or even several times in the middle and low alloy, so the benefits of carbide manufacturers generally not high. According to market research and analysis, several excellent foreign companies in the Chinese market share, in terms of volume of less than 1%, while the sales revenue, and more than 10%.

Recently, the European Commission released a list of the latest issue of critical raw materials, the list of species covered by the scope expanded from 14 kinds to 20 kinds, namely: antimony, beryllium, borate, chromium, cobalt, coke, fluorspar, gallium , germanium, indium, magnesite, magnesium, natural graphite, niobium, platinum group metals, phosphate rock, heavy rare earths, light rare earths, silicon metal, tungsten.

Reported that the EU select the type of key raw materials have two major considerations: economic importance and supply risk. 2010 the European Commission to define ad hoc working group of key raw materials, from the EU's point of view, the selection of the 14 categories of key raw materials from 41 categories of non-energy, non-food raw materials. In 2011 the European Commission formally adopted the list, and a statement of key raw materials continue to monitor the issue, then at least once every three years to update the list of critical raw materials. This evaluation will range from 41 class alternative raw materials to expand to 54 classes. The main changes in the new issue of inventory compared with the original list are: First, the rare earths are divided into two categories: light rare earths and heavy rare earths; Second, tantalum out of the list; Third added six kinds of key raw materials: beryllium, boric acid salt, coke, magnesite, phosphate rock and metal silicon. Reported that the global supply system, monitoring and evaluation of raw materials are 54 classes in about 90% originating in non-EU regions, China is an important supplier of many raw materials. In the 20 kinds of key raw materials, in the global supply of Chinese products has an important impact on 14 species, individual country occupies an important position in the other specific types of supplies. For example, in the global supply of niobium from Brazil accounted for 92% of beryllium from the United States accounted for 90%.

Commission to define ad hoc working group of key raw materials made a number of recommendations, including taking into account the risk of key economic importance and supply of raw materials, the initiative to take the necessary action to ensure that the EU can be a reliable and uninterrupted access to raw materials.
