China's automobile industry to promote the development of cemented carbide cutting tools

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.
