1, cutting tool materials and coating technology

 

Modern metal cutting tool material from carbon tool steel, high-speed steel development to todays hard alloy, cubic boron nitride and other superhard cutting tool material, cutting speed from a few meters per minute soared to km and even thousands of meters. With the continuous development of numerical control machine tools and difficult processing materials, cutting tool actual unmanageable. In order to realize high speed cutting, dry cutting, hard cutting must have a good cutting tool materials. In the many factors affecting the development of metal cutting, the cutting tool material plays a decisive role.

 

With the continuous development of numerical control machine tools and difficult processing materials, pressure on metal cutting efficiency, make the cutting tool material progress and plays a decisive role. Modern metal cutting tool material from carbon tool steel, until today in development of high speed steel, cemented carbide, coated cemented carbide, ceramics, cubic boron nitride and other superhard cutting tool material, cutting speed from a few meters per minute soared to km is even higher.

 

2006 U.S. cutter blade in consumption of material consumption, respectively is: carbide accounted for 76.7%, 6.7% ceramic blade and metal ceramic blade 4.7%, CBN and PCD superhard blades 8.8%, other blade accounted for 3.1%; Cemented carbide cutting tool materials and coating technology continuous development, make its in modern cutting occupy market share is more and more heavy, constantly eroding the market share of the high speed steel tools. High speed steel material also has a great progress. For some of the cutting tool and machining state, high speed steel cutting tools for good tenacity still occupies a share. Metal cutting tools worldwide in 2003 (not including cutting tool) consumption amount to about $11 billion, including blade and stem 48% ($5.28 billion), high speed steel cutting tools account for 36% ($3.96 billion), whole or welding carbide cutting tools account for 16% ($1.76 billion).

 

2, cutting tool integrated application of concept, the concept of system engineering

 

Cutting tool manufacturers, machine tool in the new project cooperation with customers, during the bidding process will keep close contact with relevant partners, the implementation of some key technologies and analytical processing technology and application of tools influence on the product cost, for example, how the clamping parts to maintain the stability of the processing, the cutting tool how to distribution, should adopt what kind of processing strategies, and whether you need special tools, etc.; All processing technology and flexible degree also depends on whether the customer requires running 24 hours a day.

 

Manufacturing cost lowering required pressure forced to suppliers and other large quantities of spare parts manufacturers from all over the world carefully calculated the parts cost. In order to meet the customers requirements, in the world machine tool manufacturer and cutting tool manufacturers are more closely, rather than stay in the single cutting tool selection, procurement and supporting. Because to modify an existing technology or halfway to participate in the project cooperation, need to pay more. Early intervention, for the new production line is equipped with high efficient combination tool, at the same time, given the CBN cutting tools economy depends largely on the uniformity of workpiece materials, in order to use CBN cutting tool instead of ceramic and metal cutting tool to improve processing efficiency and reduce cost, also advise customers improve the quality of workpiece materials, casting the problem of uneven, can make the new production line equipment utilization rate reached 98%, the effective use degree of 85%, better play to the role of the cutting tool manufacturers.
