In recent years, automotive tool has been along the "three high and one special" on the road in constant innovation forward, move forward, and it has not stopped progress, which is undoubtedly the most gratifying. Especially in the "efficient" in particular is made considerable progress, compared with the original, the processing efficiency is improved by more than 25%. In terms of tool materials, carbide will maintain stable growth, further reduce the market share of high-speed steel, and super-hard materials will change with the workpiece material and growth, but the growth rate is not too large, occupying mainstream position in a long period of time is still carbide.       Auto tool change in the "three high and one special" (high efficiency, high precision, high reliability and specialization) on, along with the rapid development of the automotive industry and development. Rising automobile manufacturing program, improve cycle times, led the tool manufacturing industry to accelerate the development of new technologies, tools from consumables converted into high value, high-tech products. Progress tool material, tool coating, tool construction, tool cutting parameters obtained belong to the crystallization of modern technology. Development of new cutting tool materials, wear-resistant coating, tool construction and other aspects of digital manufacturing technology, have been applied in actual production. Cutting speed reached 4000m/min, spindle speed 15000 ~ 20000r/min etc. is a common parameter; coating technology development that composite multilayer gradient structures, nano-structure, accelerate the use of actual production and promotion; New developments knife auxiliary structure to shorten the processing time adjustment process to meet and bring security, such as quick-change HFS10 Mapal shank applications; ATC CNC machining centers to shorten the time and so are the "three high and one dedicated "a welcome change.     It should be said automotive panel die cutting tools have a lot of changes over the past decade, one variety, on the scale of any tool manufacturer are carried out according to the different needs of customers refinement and offer more options as far as possible , different processing environments have more choices for; Second, the quality of a lot of progress, which is particularly reflected in the life and precision tools; Third tool prices are also rising.     Currently, more and more vehicles, especially cars to join our ordinary family, with the domestic and foreign automobile manufacturers increasingly fast car production base set up and transferred to China, the tool in the automotive powertrain applications, the more increasingly common. Its own characteristics and future development in the industry is also increasingly concerned. As tends to be lightweight powertrain manufacturing, structural simplicity, high performance, powertrain manufacturing technologies and processes have undergone great changes, high speed, high efficiency, flexibility is the main features of the current manufacturing process, which is consistent with the modern automobile industry more variety, small batch production requirements. As a powertrain manufacturing technology in a very critical part, and now the mainstream automotive powertrain features of the tool are increasingly reflects the modern automobile industry production requirements, specific performance: up points from the powertrain requirements, high- quality, high stability, high efficiency; From the technical point, high-speed, complex, specialized, standardized, multi-species, heavy haul. The tool is toward the automotive industry tool integration, environmental protection tool, tool management, outsourcing the development of future advanced mode.     As one of the typical user automotive tools, I think, is now getting close to being a tool user's needs. Some typical process of new material processing tools, special tools have been fully promoted.      1) For example, the seat tube bore aluminum cylinder head material, we applied the reamer diamond material processing, tool life can reach 30,000, were processed surface finish. Practical application of the diamond cutting tool material, reducing the frequency of the grinding tool, the tool is assembled and disassembled, the replacement frequency. Meanwhile cutter speed, high cutting speed, processing time is short, reflecting the "high-efficiency and high stability" of the tool.     2) As another example, an aluminum material cylinder engine equipped with a threaded hole 瓦盖安 we used tap extrusion processing, this processing method to produce a threaded hole, with high wear resistance, good resistance assembly. This processing step that is on the front bottom hole machining high quality requirements, we used a reamer reaming. This reflects the tool "high stability, high accuracy of."     3) a strong professional performance tool. A special tool, you can accomplish the same position, the multi-stepped holes, asymmetrical shape of a one-time processing, which greatly reduces the process steps to avoid multiple additional equipment, waste personnel.
