The new concept of cutting processing

The new concept of cutting processing

The nowadays cutting tool company cannot only be again the manufacture and the sales cutting tool, in order to succeed, Precision CNC machining parts  they must be consistent with the globalization manufacture tendency maintenance, through enhances the efficiency, cooperates with the customer reduces the cost. Approaches the instantaneous global competition after this after NAFTA, the WTO time, the world company is making quickly to the same feeling, is lighter, a cheaper response. In other words, they make the product and the components contain can in high speed under revolve, as a result of the cost pressure, best, is lighter moreover must make cheaply. Obtains these goals a best way is through develops and applies the new material, but these is new and the improvement material usually all with difficulty processes. In in this kind of commercial power and the technical difficulty combination is especially prominent in the automobile and the aviation industry, and has become has the experience the cutting tool company to research and develop the department the most important driving influence.

For example, takes the modular cast iron to say that, it has become the engine part and other automobiles, the agriculture the material which see day by day with the equipment and in the machine tool industry components. Precision CNC machining parts This kind of alloy provides the low production cost and the good machine capability combination. They are cheaper than the steel products, but has a higher intensity and toughness compared to the cast iron. But at the same time the modular cast iron is extremely wear-resisting, has fast breaks by rubbing the cutting tool material the tendency. In this wear resistant very great degree bead luminous body content influence. Some known modular cast iron bead luminous body content higher, its resistance to wear better, moreover its machinability is worse. Moreover, the modular cast iron porosity causes off and on to cut, this even more reduces the life.

May estimate that, PrecisionCNC machining parts the high degree of hardness and the high wear-resisting cutting material quality must consider the modular cast iron the high resistance to wear. And the material quality contains extremely hard TiC in fact (carbonized titanium) or TiCN (carbon titanium nitrides) thick coating when cutting speed each minute 300 meters processes the modular cast iron to prove usually is effective. But along with cutting speed increase, scrap/The cutting tool junction

 plane temperature also is increasing. When has such situation, the TiC coating favors in has the chemical reaction with the iron and softens, more pressures function in anti- crescent moon hollow attrition coating. Under these conditions, hoped has one chemical stability better coating, like Al2O3 (although under low speed was inferior to TiC hard or is wear-resisting).

  

The widespread application of advanced manufacturing technology

The widespread application of advanced manufacturing technology,  

Precision CNC machining parts Advanced manufacturing technology is relatively conventional manufacturing techniques in the application scope of a major difference is that traditional manufacturing techniques are usually only refers to a variety of raw materials into finished products processing technology, and advanced manufacturing technology, although still a large number of application processing and assembly processes, However, because of its composition including the design technology, automation 

technology, systems management technology, which will be applied to its consolidated the whole process of manufacturing, covering product design, production preparation, processing and assembly, sale use, maintenance services and even the recycling of the the whole process. 

  The dynamic characteristics of advanced manufacturing technol

 Precision CNC machining parts  As advanced manufacturing technology itself is the target for a certain application, absorbing a variety of high-tech gradually formed, the continuous development of new technologies, and therefore its meaning is not absolute and immutable. Is reflected in the different periods, advanced manufacturing technology has its own characteristics; also reflected in the different countries and regions, advanced manufacturing technology has its own focus on the development objectives and content, by focusing on the development of content in order to achieve the national  and regional manufacturing technology by leaps and bounds. 

  The integration of advanced manufacturing technology    

Precision CNC machining parts Traditional manufacturing technology, professional single independent and distinct boundaries between them; advanced manufacturing technology, professional and interdisciplinary due to the continuous infiltration, cross, integration, boundaries gradually fade or even disappear, technology tends to systematic, integrated, has developed into a set of machinery, electronics, information, materials and management techniques for the integration of a new cross-disciplinary. So you can call it a "manufacturing engineering."

   

The Numerical Control Engine Bed Transforms

The Numerical Control Engine Bed Transforms

 Numerical control system development summary brief history and tendency

 In 1946 the first electronic accounting machine was born in the world, this indicated the humanity created has been possible to strengthen and partially to replace the mental labor the tool. Cnc machining It with the humanity these which in the agriculture, the industry society created only is strengthens the physical labor the tool to compare, got up the quantitive leap, entered the information society for the humanity to lay the foundation. 

  After 6 years, in 1952, computer technology applied to the engine bed , the first numerical control engine bed were born in US. From this time on, the traditional engine bed has had the archery target change. Since nearly half century, the numerical control system has experienced two stages and six generation of development.

 Numerical control (NC) stage (1952 ~ 1970) 

  The early computer operating speed is low, was not big to then science computation and the data processing influence, but could not adapt the engine bed real-time control request. The people can not but use numeral logic circuit "to build" to become an engine bed special purpose computer to take the numerical control system, Cnc machiningis called the hardware connection numerical control (HARD-WIRED NC), Jian Chengwei numerical control (NC). Along with the primary device development, this stage has had been through repeatedly three generations, namely 1952 first generation of -- electron tube; 1959 second generation of -- transistor; 1965 third generation -- small scale integration electric circuit.

 Computer numerical control (CNC) stage (in 1970 ~ present) 

 In 1970, the general minicomputer already appeared and the mass production. Thereupon transplants it takes the numerical control system the core part, from this time on entered the computer numerical control (CNC) the stage ("which should have computer in front of the general" two characters to abbreviate). In 1971, American INTEL Corporation in the world first time the computer two most cores part -- logic units and the controller, used the large scale integrated circuit technology integration on together the chip, called it the microprocessor (MICROPROCESSOR), also might be called the central processing element (to be called CPU)

 The microprocessor is applied to 1974 in the numerical control system. This is because minicomputer function too strong, controlled an engine bed ability to have wealthily (therefore once uses in controlling the multi- Taiwan engine bed at that time, called it group control), was inferior to used the microprocessor economy to be reasonable. Moreover then small machine reliability was not ideal. The early microprocessor speed and the function although insufficiently are also high, but may solve through the multi-processor structure. Because the microprocessor is the general-purpose calculator core part, therefore still was called the computer numerical control

 In 1990, PC machine (personal computer, domestic custom had called microcomputer) the performance has developed to the very high stage,Cnc machining may satisfiedly take the numerical control system core part the request. The numerical control system henceforth entered based on the PC stage.  In brief, the computer numerical control stage has also experienced three generations. Namely 1970 fourth generation of -- minicomputer; 1974 five dynasties -- microprocessor and 1990 sixth generation -- (overseas was called PC-BASED) based on PC.

   Also must point out, although overseas already renamed as the computer numerical control (namely CNC).  

  Also must point out, although overseas already renamed as the computer numerical control (namely CNC), but our country still the custom called the numerical control (NC). Therefore we daily say "numerical control", the materially already was refers to "computer numerical control".
