Due to the high concentration of modular machine tool process, namely, in a machine can finish at the same time one of several different process, so used to the yield, high precision production request, and overcome the universal machine structure is complex, labor intensity and low production efficiency and precision is not easy to ensure shortcomings, and special machine tool poor universality and does not meet the modern technology rapid deve lopment, product often demand. So, combination machine tools and automatic line has been widely applied to car, diesel engine, motor, instruments and military products, production, and shows great superiority. In combination machine tools on complete drilling, reaming, boring, tapping, turning, milling, grinding and rolling process, high efficiency, the processing accuracy stable. Combination machine tools and automatic line is set for the mechanical and electrical in an integrated automation and higher manufacturing technology and process equipment packages, and its features are high efficiency, high quality,economical and practical, they are widely used in cars, trucks and tractors, diesel engine, motor, instruments and military industry department, in recent years, along with the fixed assets increases, and this will be for the machine . China market with very large space, to join the WT0, and the world has been further machine tool industry standards, and many advanced machine will be deve loped, true to the numerical control, flexibility to change. 中文譯文 組合機床是根據(jù)工件加工需要，以大量通用部件為基礎，配以少量專用部件組成的一種高效專用機床，主要用于平面加工和孔加工兩類工序，按通用部件類型，組合機床分為大型和小型兩大類，用大型通用部件組成的機床稱為大型組合機床，用小型通用部件組成的機床稱為小型組合機床;按配置型式又分為單工位和多工位機床兩大類，單工位機床又有單面、雙面、三面和四面幾種;多工位機床則有移動工作臺式、回轉工作臺式、中央立柱式和回轉鼓輪式等配置型式。 由于組合機床工序的高度集中，即在一臺機床上可同時完成一種或幾種不同工序加工，因此適應了產量大、精度高的生產要求，并且克服了萬能機床結構復雜、勞動強度大、生產效率低、精度不易保證的缺點，以及專用機床通用性差、不適應現(xiàn)代技術迅速發(fā)展、產品經常更新的要求.所以，組合機床及其自動線已廣泛應用到汽車、柴油機、電動機、儀器儀表以及軍工產品等的生產上，并顯示出巨大的優(yōu)越性。 在組合機床上完成鉆孔、擴孔、鉸孔、鏜孔、攻絲、車削、銑削、磨削及滾壓等工序，生產效率高，加工精度穩(wěn)定。組合機床及自動線是集機電于一體的綜合自動化及較高的制造技術和成套工藝裝備，它的特點是高效，高質，經濟實用，因而被廣泛應用于汽車、卡車、拖拉機、柴油機、電動機、儀表及軍工部門，近幾年來，隨著我國固定資產不斷增加，這將為我國的機床市場帶來很大的空間，加入WTO后，與世界機床行業(yè)有了進一步的接軌，很多先進的機床將被研發(fā)出來，真正向數(shù)控化，柔性化轉變。
