1原文:Modern machinery processing and manufacturing technology from the higher precision and production efficiency developed rapidly both at the same time. Improve production efficiency in recent years, CAD / CAM technology, CNC technology, CIMS technology very widely used, making the production efficiency is greatly enhanced. In improving the machining accuracy, precision machining, ultra precision machining and even nano-processing is the direction the world is committed to developing its precision from micron to sub-micron level, and even nano-level, in the defense, aerospace, nuclear power and the high-tech economy wide field of applications. With the development of science and technology, machining accuracy can be achieved by a rapid increase. Literature at home and abroad are talking about precision ultra-precision machining, generally refers to the micron level (shape and size of error is 3 to 0.3 microns) to achieve high-precision machining, machine tool equipment must be designed in from all directions which is committed to improving its precision. With the development of science and technology, machining accuracy can be achieved by a rapid increase. Literature at home and abroad are talking about precision ultra-precision machining, generally refers to the micron level (shape and size of error is 3 to 0.3 microns) to achieve high-precision machining, machine tool equipment must be designed in from all directions which is committed to improving its precision. Currently, the international reciprocating table surface grinding machine speeds up to 200m/min, plus tableSpeed 50m/s2. Of course, this is achieved by linear motor after this level. Indeed, the use of new features to improve the performance of the host machine from a very big role High-speed travel grinding, also known as rapid short stroke grinding, this method is high speed and high acceleration table for grinding. Although this method more than 20 years of history, but rapid development in recent years. Transmission from the DC motor into a toothed belt or ballscrew drive linear motor drive, its movement is faster, more efficient and a wider range of applicationsHigh-speed the past 2 years, the European high-speed travel faster grinding get progress, supported by the European Union, a subject called AGNETA by BLOHM, INA, ROLLS-ROYCE and other manufacturers and universities to participate, after several years of basic research and applications Study, in September 2004 on the success of the project intended to achieve two main objectives - to reduce processing costs by 40% and 50% reduction of grinding time. View from the grinding mechanism, grinding high-speed travel is not a new way of processing, but a variant of grinding or surface grinding of the extension. In short, high-speed grinding technology is a new itinerary effective grinding method, for difficult to machine materials and hard materials with great potential.High grinding center of the small, practical, and composite, grinding center development for over 20 years of history, with the grinding technology and computer technology continues to progress, grinding centers, manufacturing has improved continuously . Grinding Center is a flexible grinding system, its technology is based on mechatronics and computer technology. Grinding machining center machining center can be divided into conventional grinding type and extension of extension of type two. From 2005 to see the European Machine Tool Exhibition, the exhibition center is grinding grinding extension type, the grinding machine from a simple exchange of the original development of the grinding wheel and milling, and drilling tool hybrid exchange for a fixture in the workpiece after the completion of all processing operations. Therefore, the development trend of grinding machining center is a small, practical, and composite. Overall enhanced grinding and hard machining technology competition.Foreign-class machine tool manufacturers have strong capability of independent innovation, at each key can be found on the machine tool exhibition highlights innovative. For example, in the 2005 European Machine Tool Exhibition, MAEGERLE the company unveiled the latest MFP a CNC grinding machine, the machine in the world for the first time using the latest drive technology and Siemens latest generation of CNC SINUMERIK line control device. The new hydrostatic drive technology in addition to the existing rail outside the X-axis is also the first time, hydrostatic screw. The new components to ensure that vibration is usually generated by screw to minimize, to provide line-driven than 15 times higher dynamic rigidity. Its advantages are: the largest damping and feed force, coupled with the screw shaft and nut to run between the wear-free. In addition, compared with the linear drive, low energy consumption to more than 10 times, will not produce any heat.2翻译: 现代机械加工制造技术从提高加工精度和生产效率两个方面同时迅速发展起来。在提高生产效率方面,近年来CAD/CAM技术、CNC技术、CIMS技术的发展极其广泛应用,使得生产效率得到大幅度的提高。在提高加工精度方面,精密加工、超精密加工乃至纳米加工是世界各国致力发展的方向,其精度从微米级到亚微米级,乃至纳米级,在国防、航天航空、核能以及国民经济各高新技术领域得到广泛应用。随着科学技术的发展,机械加工所能达到的精度得到了飞速的提高。目前国内外文献中谈论的精密超精密加工,一般指微米级(形状尺寸误差为30.3微米)为实现高精度的加工,必须在机床设备的设计当中从各个方向致力于提高其加工精度。 目前,国际上平面磨床工作台往复速度最高可达200m/min,工作台的加速度50m/s2。当然,这都是采用直线电机后才达到了这个水平。确实,新功能部件的使用对提高机床主机的性能起了非常大的作用高速行程磨削,也称为快速短行程磨削,这种方法是以高的工作台速度和高的加速度进行磨削加工。虽然,这种方法已有20多年的历史,但最近几年的发展较快。传动方式由原来的直流电机齿带或滚珠丝杠传动变为采用直线电机驱动,其运动速度更快,效率更高,应用范围更广。近2年,欧洲高速行程磨削得到较快的进步,由欧盟支持的一项称为AGNETA的课题,由BLOHM、INA、ROLLS-ROYCE等厂家和大学共同参与,经过几年基础研究和应用研究,2004年9月就取得成功,实现了该项目预定的2个主要目标减少加工费用40%和减少磨削时间50%。从磨削机理看,高速行程磨削并不是一种全新的加工
