The numerical control transformation content and superiorly lacks

The numerical control transformation content and superiorly lacks
 Transformation industry starting 
 In US, Japan and Germany and so on the developed country, their engine bed transforms took the new economical growth profession, cnc machine center thrives abundantly, is occupying the golden age. As a result of the engine bed as well as the technical unceasing progress, the engine bed transformation is "the eternal" topic. Our country's engine bed transformation industry, also enters from the old profession to by the numerical control technology primarily new profession. In US, Japan, Germany, have the broad market with the numerical control technological transformations engine bed and the production line, has formed the engine bed and the production line numerical control transformation new profession. In US, the engine bed transformation industry is called the engine bed regeneration (Remanufacturing) industry. Is engaged in the regeneration industry famous company to include: The Bertsche engineering firm, the ayton engine bed company, Devlieg-Bullavd (are valuable) serves the group, the US equipment company and so on. The American valuable company has set up the company in China. In Japan, the engine bed transformation industry is called the engine bed to reequip (Retrofitting) industry. Is engaged in the reequipment industry famous company to include: Big indentation project group, hillock three mechanical companies, thousand substitute fields labor machine company, wild  engineering firm, shore field engineering firm, mountain this engineering firm and so on
 Numerical control transformation content
 The engine bed and the production line numerical control transformation main content has following several points: 
  First is extensively recovers the function, to the engine bed, the production line has the breakdown partially to carry on the diagnosis and the restoration;    
   Second is NC, the addend reveals the installment on the ordinary engine bed, or adds the numerical control system, transforms the NC engine bed, the CNC engine bed;     
  Third is renovates, for increases the precision, the efficiency and the automaticity, to the machinery, the electricity partially carries on renovates, reassembles the processing to the machine part, extensively recovers the precision; Does not satisfy the production request to it the CNC system to carry on the renewal by newest CNC;     
  Fourth is the technology renews or the technical innovation, for enhances the performance or the scale, or in order to use the new craft, cnc machine center the new technology, carries on the big scale in the original foundation the technology to renew or the technical innovation, the great scope raises the level and the scale renewal transformation.  
  The new electrical system transforms after, how carries on the debugging as well as the determination reasonable approval standard, also is the technology preparatory work important link. The debugging work involves the machinery, the hydraulic pressure, the electricity, the control, and so on, therefore must carry on by the project person in charge, cnc machine center other personnel coordinate. The debugging step may conform to simplicity to numerous, from infancy to maturity, carries on from outside to in, after also may the partial overall situation, after first the subsystem.

Mold materials and surface treatment technology& new techniques

Mold materials and surface treatment technology& new techniques
 Industry to the level of mold, material application is the key. Due to improper selection and use of materials, causing premature die failure, which accounts for more than 45% failure die. In the mold material, Cnc machining  commonly used cold work tool steel with CrWMn, Cr12, Cr12MoV and W6Mo5Cr4V2, flame hardened steel (such as Japan, AUX2, SX105V (7CrSiMnMoV), etc.; used a new type of hot work die steel American H13, Sweden QRO80M, QRO90SUPREME, etc.; used a pre-hardened plastic mold steel  (such as the U.S. P20), age-hardening steel (such as the U.S. P21, Japan NAK55, etc.), heat treatment hardened steel (such as the United States, D2, Japan, PD613, PD555, Sweden wins the White 136, etc.), powder die steel (such as Japan KAD18 and KAS440), etc.; panel drawing die used HT300, QT60-2, Mo-Cr, Mo-V cast iron, large-scale mold with HT250. more regular use of Precision Die Hard Steel Results YG20 and other alloys and carbide. in the mold surface treatment, the main trends are: the infiltration of a single element to the multi-element penetration, Cnc machining complex permeability (such as TD method) development; by the general diffusion to the CVD, PVD, PCVD, ion penetration , the direction of ion implantation, etc.; can use the coating are: TiC, TiN, TiCN, TiAlN, CrN, Cr7C3, W2C, etc., while heat from the air treatment means to the development of vacuum heat treatment. In addition, the current strengthening of the laser, glow plasma Nitriding and electroplating (plating) enhanced anti-corrosion technologies are also more and more attention.
  In the forming process, the main function of composite stamping die, superplastic forming, plastic precision molding technology, plastic mold gas-assisted injection technology and hot runner technology, high-pressure injection molding technology.  On the other hand, with the continuous development of advanced manufacturing technology and raise the level of mold industry as a whole, in the mold industry, Cnc machining there are some new design, production, management ideas and models. Concrete are: to adapt to the characteristics of mold-piece production flexible manufacturing technologies; to create the best management and effective teamwork, lean production; to enhance rapid response capabilities of Concurrent Engineering, Virtual Manufacturing and global agile manufacturing, manufacturing of new production networks philosophy; extensive use of standard parts common parts of the division of work mode of production; meet the environmental requirements of sustainable development and green design and manufacturing.

Mold software applications, networking trend

Mold software applications, networking trend
 With the mold in the enterprise competition, Cnc machining cooperation, production and management, globalization, internationalization, and the rapid development of computer hardware and software technology, the Internet has made in the mold industry, virtual design, agile manufacturing technology both necessary and possible. The United States in its "21st Century Manufacturing Enterprise Strategy" that the auto industry by 2006 to achieve agile manufacturing / virtual engineering solutions to automotive development cycle shortened from 40 months to 4 months.
 Mold testing, processing equipment to the precise, efficient, and multi-direction
 mold testing equipment more sophisticated, efficient
 Sophisticated, complex, large-scale mold development, testing equipment have become increasingly demanding.  Precision Mould precision now reached 2 ~ 3μm, more domestic manufacturers have to use Italy, the United States, Japan and other countries in the high-precision coordinate measuring machine, and with digital scanning.  Cnc machining  Such as Dongfeng Motor Mould Factory not only has the capacity 3250mm × 3250mm Italian coordinate measuring machine, also has a digital photography optical scanner, the first in the domestic use of digital photography, optical scanning as a means of spatial three-dimensional access to information, enabling the establishment from the measurement of physical model output of engineering drawings the whole process of mold making, reverse engineering a successful technology development and applications.  This equipment include: second-generation British Renishaw high-speed scanners (CYCLON SERIES2) can be realized and contact laser probe complementary probe, laser scanner accuracy of 0.05mm, scanning probe contact accuracy of 0.02 mm.  Another German company GOM ATOS portable scanners, Japan Roland's PIX-30, PIX-4 desktop scanner and the United Kingdom Taylor Hopson's TALYSCAN150 multi-sensor, respectively Three-dimensional scanner with high speed, low-cost and functional composite and so on

 CNC EDM   Japan Sodick linear motor servo drive using the company's AQ325L, AQ550LLS-WEDM have driven fast response, transmission and high positioning accuracy, the advantages of small thermal deformation. Switzerland  Cnc machining Chanmier company NCEDM with P-E3 adaptive control, PCE energy control and automatic programming expert systems.  Others also used the powder mixed EDM machining technology, micro-finishing pulse power and fuzzy control (FC) technologies.
