KONTUR 編程語言對砂輪進行成型修整，并有圖形輔助操作功能。日本岡本公司在FANUC公司數(shù)控系統(tǒng)硬件上，開發(fā)了OPL語言用于磨削加工，等等。 當今直線電機、動平衡等技術(shù)、工藝的日益發(fā)展應(yīng)有，又大大提高了機床的工效，適宜的測量技術(shù)應(yīng)用對數(shù)控系統(tǒng)的開發(fā)利用，增強機床的電氣自動控制功能如虎添翼。 二、國內(nèi)數(shù)控平磨的發(fā)展 我國從80年代開始生產(chǎn)數(shù)控平面磨床，各開發(fā)廠家分別走過了自行研制，與大學及科研單位合作開發(fā)至直接引進成熟數(shù)控系統(tǒng)的發(fā)展道路。例如：杭州機床廠是一家具有五十年歷史，專業(yè)生產(chǎn)平面磨床的制造廠，它從80年代中期開始生產(chǎn)數(shù)控平磨，先后開發(fā)生產(chǎn)了MGK7132臥軸矩臺高精度平磨，MK7130系列普通數(shù)控平磨，MLK7140數(shù)控緩進給成型磨，MGK7120、MK7163、MK7150臥軸矩臺數(shù)控平磨，MKY7760立軸數(shù)控雙端面磨，MKY7660、MKY7650/101臥軸數(shù)控雙端面磨，以及HZ-K1610，HZ-K2010，HZ-050 CNC，HZ-KD2010、HZ-K3015、HZ-K3020、HZ-K4020等專用數(shù)控龍門式平面與導軌磨床。數(shù)控系統(tǒng)的開發(fā)應(yīng)用，有與大專院校及科研單位合作研制的單板機系統(tǒng)，也有自行開發(fā)的以單片機為主機的簡易控制系統(tǒng)，及采用數(shù)控主機廠生產(chǎn)的成熟數(shù)控系統(tǒng)等。 ??? 其生產(chǎn)的MGK7120高精度平磨，采用了日本FANUC公司的POWER MATE-D雙軸數(shù)控系統(tǒng)，控制磨頭進給，最小進給量0.1μm，具有自動完成磨削循環(huán)功能。 ??? MKY7650/101全自動數(shù)控雙端面磨床是與意大利VIOTTO公司技術(shù)合作產(chǎn)品，采用西門子SIMATIC S5-115U可編程控制器控制，CRT顯示，機床的左、右磨頭由二軸直流伺服電機驅(qū)動，機床能進行手動調(diào)整和自動磨削循環(huán)選擇。配有意大利馬爾波斯E9型測量系統(tǒng)，二個測量頭，一個測量砂輪，將砂輪磨損量反饋給控制系統(tǒng)，進行砂輪補償；另一個測量頭測量磨削后的工件，并將測量結(jié)果輸入控制系統(tǒng)，由伺服電機進行補償進給；左、右磨頭用VIOTTO光柵作位置測量控制，實現(xiàn)了整機從工件上料到磨削完畢的全閉環(huán)和全自動加工。 ??? HZ-050CNC數(shù)控直線滾動導軌專用磨床，是為上海市科技結(jié)合生產(chǎn)重點工業(yè)項目第三次科技攻關(guān)項目而開發(fā)的專用磨床。既具有平面磨削功能又有成型磨削功能，它采用了美國A-B公司生產(chǎn)的8400MP數(shù)控系統(tǒng)，機床有7根數(shù)控軸，X、Y、Z三根磨頭進給軸和U、V、W三根砂輪修整軸由系統(tǒng)直接控制，另一軸Q為臥式砂輪橫向進給（磨削平面用）通過SLC可編程控制器加IMC定位模塊，由系統(tǒng)I/O口輸入8400MP主機，控制其位置，具有在磨削中連續(xù)修整砂輪或間隙式砂輪修整補償進給等自動加工能力。 ???

Therefore advanced manufacturing technology will be quickly won the competition and survival of the enterprise, the principal means of development. Computer information technology and manufacturing automation technology more closely integrated, flexible production automation as an important foundation for digital machine in the production of machine tools to share more. First, digital Ping finds the status quo and digital systems primaril. First, digital Ping finds the status quo and digital systems primarily. Horizontal grinder compared to the lathe, milling machine, using digital systems later, the special requirements because of its digital systems. In the past decade, with the technical facility, grinder, the grinding wheel for repair, automatic compensation, automatic exchange grinding wheel, and more workstations, such as automatic transmission and Zhuangjia working inoperable realized, and digital technology in the horizontal grinder, gradually spread. In recent Hanover, Tokyo, Chicago, and other large domestic machine tool exhibition, CNC grinder throughout the grinder, for the majority of the exhibits, such as Germany Blohm company ELB companies such famous grinder factories no longer produce ordinary grinder Japanese Forces, Japan, the company also Hing bulk production facility-wide functional ping himself. in the development of high-grade digital ping himself while actively developing, low digital ping himself. German production company a few years ago ELB brilliant series two coordinates facility shaped grinder, the vertical and horizontal axis for digital, vertical for hydraulic control, grinding wheel repair work platform installed in a roller diamonds, the application of broader; SUPER-BRILLIANT series is one-dimensional and shaped grinder Sanzuobiao facility, the beds are manufactured using natural granite, high geometric accuracy, slide away from straight rolling guide, driving without recoiling machinery, thus ensuring a better working surface smoothness; BRILLIANT-FUTURE series of improvements to the above two products, using artificial granite bed was produced by static pressure vertical guide, Chixing belt transmission, vertical and horizontal guide for pre reinforced straight rolling guide, Gunzhusigang transmission, three-axis CNC control AC servo electrical, measuring 0.5 m 16ug image. ELB company has also developed the latest technology grinder contemporary products, and integration with computer and technology-based series of soft skills CAM-MASTER processing modules CAD-MASTER series and COMPACT-MASTER series grinding processing center, a maximum of up to 24 axis control axis, As the full implementation of modular design and manufacture of dedicated grinder cycle shortened ELB company has also developed a variety of highly efficient dedicated grinder, such as SFVG100/2 dedicated grinder, which will tilt Motou, continuous improvements, to ease into, ramps while grinding function with 11 root axis CNC control, as one finds processing center. British and American companies JONES&SHIPMAN A-B company developed A-B8600 digital systems for digital FORMAT5 type ping himself from the facility hydraulic control valves, driven vertical movement can be governor, to the use of horizontal and Motou into Gunzhusigang deputy, Electrical DC servo-driven, intermittent style grinding wheel repair, CRT graphics simulation showed.

Currently, the semiconductor master degrees continual increase in the newly introduced system in the appearance of smaller, more compact structure, functions increased distance communications, remote diagnosis, multiple plane networking etc.; Interface to the Windows operating system to increase the mouse, remote operation of vehicles. Fanuc major company this year launched 18I, 16I, 20I, 21I system Siemens is 840D, 810D, 802D are tight structure type system. There are a number of manufacturers such as : Taiwan Precision Machinery Research and Development Center developed PA8000NT series CNC controls on the use of the Windows operating system of NC, and NT immediate multi-processing core, single-section procedures for processing speed 2,000 pieces / s, single-section pre-1000 time to deal with a few pieces, with Aart (pre-adaptation technologies) and the parameters of the best learning function would follow error convergence to zero, the software processing path filter to reduce machining process generated by the acceleration changes excessive mechanical resonance, thereby improving surface roughness; with the use of servo flexible, with +, -10V analogy servo interface It also provides international standards SERCOS digital servo communications interface design Tixingtu ;PLC procedures, structure expressions, functional pieces, instructions code, flowcharts, five grammar, facilitate design, communication and maintenance; long-range communications with the computer, instant remote maintenance functions; control can be extended to a maximum axle and spindle axis 64. I/O points which can be expanded to 792/528 point, the introduction of Pentium processors, high-speed Plc processing speed to 25K. Apart from the world famous Siemens, Fanuc digital systems, such as professional development and production of the plant has been applied to many horizontal or shaped grinding system, a number of production plants Ping finds itself actively developed application in the digital grinder system. Notably : Siemens SINUMERIK 840D of the system, the system has more than 20 roots servo axis, the coordinates for the trip control, manual data entry or imported through external computer, remote diagnosis may reduce the grinding wheel diameter change itinerary, grinding wheel repair of automatic compensation Gunzhusigang gap error compensation. Siemens 3G system is specifically for grinding and processing development, for both dialogue with the presentation devices operate in axis tilt, can also be straight and arc widely in grinding, recurring operational cycle, such as the main axis swing, and use external signal interruption implementation procedures, grinding wheel cut, grinding wheel repair, and other special functions for the preparation of a fixed cycle procedures. Not only can use its external measurement devices (switches signal), but when connected to a suitable time to first measurement and control devices directly to the ultimate size comparison. American companies ALLEY-BRANDLY production 8400CNC, 8600CNC digital series apply lathe, milling machine and grinder, 8400CNC up to 6 roots servo axis control, the Section 2 axle may drain, the three axis may helix spaced, six axle straight drain. 8600CNC series of coordinates to control 17, including eight in the drain axle, eight spaces control axle and one allegation that a graphic shown that the expansion of branch procedures that processing time, high-speed access procedures, cutlery life monitoring function. Japanese companies developed FANUC OG high-speed high-performance digital systems, which O-GSG applicable to horizontal grinder, the grinding parts under different shapes, four different methods of grinding, a grinding wheel axle angle control function shortage grinding, Cumo, Jingmo, no spark grinding a grinding cycle of grinding wheel flow position after finishing compensation function, Compared to repair vehicles were repaired round normal line direction control functions roller outer arc radius compensation for the rehabilitation of the functional, grinding wheel shape graphics and grinding parameters show that the functional, system smallest unit set 0.1 16ug m, a "tight" - type digital systems, lower prices. There are also companies such as Germany and the University jointly developed by ELB UNICON system.

Although there is the ping himself factory using digital Zhujichang system, but self-development of software, use it more suitable for horizontal and shaped grinding, such as German company Siemens SINUMERIK 810 Jung based, the company specialized software used by Jung Kontur programming language for a shaped grinding wheel repair, and graphics supporting operational functions. Japan sincerely companies in Fanuc digital systems hardware companies, the OPL development language for grinding processing, and so on. The linear electrical, balance, technology, the growing due process, and greatly enhance the efficacy of machine tools, the application of appropriate measurement techniques for the development and use of digital systems, machine tools and electrical automatic control functions to redouble their might. Second, the development of domestic digital Ping finds. Since the start of production digital horizontal grinder 1980s, the development of the manufacturers have developed separately, the development of cooperation with universities and research units direct to introduce mature digital systems development. For example : Hangzhou Machine Tool Plant is a history of 50 years of professional graphic grinder of factory production, which began production in the mid-1980s from digital ping himself, has developed a production MGK7132 straight axle rule Taiwan high-precision ping himself, MK7130 series ordinary digital ping himself, MLK7140 digital relief to shape himself into, MGK7120, MK7163, MK7150 straight axle rule Taiwan digital ping himself, MKY7760 vertical shaft digital double carry noodles himself, MKY7660, MKY7650/101 straight axle digital double carry noodles himself, and HZ-K1610,HZ-K2010,HZ-050 CNC,HZ-KD2010, HZ-K3015, HZ-K3020, such as dedicated digital Dragon Gate Type HZ-K4020 horizontal grinder and guide. The development and application of digital systems, developed in cooperation with universities and scientific research units in the Shanbanji system, but also for self-development to the mainframe Chanpianji the simple control system, and the use of digital Zhujichang mature digital production system. Ping finds its production MGK7120 high-precision, the company introduced Japan Fanuc MATE-D purchased digital recording system to control Motou chin, chin to the smallest volume 0.1 16ug m, a complete automatic grinding cycle functions.
