High speed changes linear velocity of tide emery wheel and high speed of workbench motion speed already became general trend. Because was used linear slideway, linear electric machinery, static press the advanced functional component technology such as guide screw, athletic speed has very big rise, and the scope that increase is very difficult before imagination. High speed, efficient, high accuracy and Gao Rou sex are the way that current international machine tool develops really. As technical progress, high speed is changed more and more develop to all-pervading direction. Current, rate of move back and forth of planar grinder workbench is top on international can amount to 200m/min, the acceleration 50m/s2 of workbench. Of course, this is to used the ability after linear electric machinery to reach this level. Really, the use of new function component had very big effect to improving the performance of machine tool lead plane. Grinding of journey of high speed of grinding of high speed journey, also call grinding of fast short distance, this kind of method is with tall workbench speed and tall acceleration undertake grinding is machined. Although, this kind of method already had 20 old histories, but the development of the last few years is rapidder. Transmission way is taken by original dc machine tine or drive of ball guide screw turns into introduce drive of linear electric machinery, its motion rate is rapidder, efficiency is taller, applied range is wider. Nearly 2 years, grinding of journey of European high speed gets rapidder progress, call the task of AGNETA by a when the European Union supports, participate in jointly by manufacturer and the university such as BLOHM, INA, ROLLS-ROYCE, through a few years of basic research and applied research, gained a success in September 2004, 2 when realized this project to book main goals -- reduce treatment cost 40% and reduce grinding time 50% . Look from grinding mechanism, grinding of high speed journey is not a kind of brand-new treatment means, however of planar grinding change model or be planar grinding is outspread. Anyhow, technology of grinding of high speed journey is a kind of new effective planar grinding method, to difficult treatment material and horniness material have very large latent capacity. The miniaturization of grinding machining center, practical change and compound the development that changes grinding machining center already had 20 old histories, as the ceaseless progress of grinding processing technique and computer technology, the production level of grinding machining center rises ceaselessly. Grinding machining center is a kind of flexible grinding treatment system, its technical base is Electromechanical unifinication and computer technology. Grinding machining center can be divided commonly lengthen for machining center model lengthen with groovy grinder model 2 kinds. From 2005 exhibition of European machine tool looks, exhibits grinding machining center is grinder is lengthened model, the machine tool develops emery wheel and mill from pure before wheelhead exchange, auger wait for cutting tool to mix model exchange, so that be in,workpiece completes the treatment of all working procedure after outfit clip. Accordingly, the development trend of grinding machining center is miniaturization, practical change and compound change. Grinder from the ability that enhanced to compete with hard cutting technology on the whole. Abroad of powerful own innovation ability's top-ranking machine tool makes an enterprise have powerful own innovation capacity, can discover the window of innovation on every important machine tool exhibition. Go up in the exhibition of European machine tool 2005 for instance, MAEGERLE company exhibited a grinder of newest MFP numerical control, this machine uses newest drive technology and Xi Menzi first on the world the SINUMERIK of newest generation is online device of pilot numerical control. New drive technology besides what have static press slideway beyond, still use first on X axis static press guide screw. This new assembly ensures reduce the vibration that introduces guide screw generation normally the smallest, offer steeper than using drive 15 times taller dynamic tigidity. Its advantage is: The biggest damp character and feed force, add move without tatty between guide screw axis and nut. In addition, compare with steep drive photograph, energy is used up should 10 times lower above, won't produce any quantity of heat. Still contain on exhibiting this MFP grinder Xi Menzi 840D is online device of pilot numerical control, the actuating device of this kind of new generation has the following advantage: The electron of limits of system of the coordinate combination that designs by the standard, all assembly joins. Other character is: Serial interface of the lead that holds beforehand, DRIVE-CLIQ, automatic workpiece identifies, servo and vector control and because be mixed to safeguarding,breakdown diagnoses overall support and shorter air runs time. In addition, machine tool besides have good performance, precision beyond, must have beautiful exterior and color. The exterior of the machine tool and colour have the feature of the times, evolve into roundlet horn and straight line from large round part, from compare heavy and complicated to evolve concise. Colour turns into from monochromatic double color or polychromatic, even draw has pattern. Fall in the basic structure of straight line currently, there are a few changes in modelling and detail respect, make a machine tool more beautiful and easy. CNC MillingCNC Machining
