14、產(chǎn)率高。因為工序集中，可以多面、多工位、多軸、多刀同時進行加工。(3)加工精度穩(wěn)定。因為工序固定，可選用成熟的通用部件、精密夾具和自動工作循環(huán)來確保加工精度的一致。(4)研制周期短，便于設(shè)計、制造和使用維護，成本較低。因為通用化、系列化、標(biāo)準(zhǔn)化程度高，通用件可組織批量生產(chǎn)進行預(yù)先制造或外購。(5)自動化程度高，勞動強度較低。(6)配置靈活。因結(jié)構(gòu)是橫塊化、組合化。可按照工件或工序要求，用大量通用部件和少量專用部件靈活組成各種類型的組合機

15、床和自動線；機床便于改裝：產(chǎn)品或工藝發(fā)生變化時，通用部件一般還可以重復(fù)使用。</p><p>　　組合鉆床一般用于加工箱體類或特殊形狀等零件。加工時，工件一般不旋轉(zhuǎn)，由刀具的旋轉(zhuǎn)運動和刀具與工件的相對進給運動，來實現(xiàn)鉆孔、擴孔、锪孔、鉸孔、鏜孔等加工。有的組合機床采用車削頭夾持工件使之旋轉(zhuǎn)，由刀具作進給運動，也可對某些回轉(zhuǎn)體類零件(如飛輪、汽車后橋半軸等)的外圓和端面加工。</p><p>

16、;　　組合機床一般采用多軸、多刀、多工序、多面或多工位同時加工的方式，生產(chǎn)效率比通用機床提高很多倍。由于通用部件已標(biāo)準(zhǔn)化和系列化，所以可根據(jù)需要靈活配置，就能縮短設(shè)計和制造周期。多軸箱是組合機床的核心通用部件。它是選用通用零件，是按專用要求進行設(shè)計的，在對組合機床設(shè)計的過程中，是工作量較大的部件之一。它根據(jù)組合機床設(shè)計的工序圖和加工示意圖所確定的工件加工孔的數(shù)量和位置，切削用量和主軸類型設(shè)計的傳遞各主軸運動的動力部件。多軸箱動力來自通用

18、用部件，它一定會引起組合機床通用件發(fā)生根本型變化。近十年來，組合機床及其自動線在高效、高生產(chǎn)率， 柔性化以及采用并行工程制訂更合理、更節(jié)省的方案方面取得了很大的進展。近年來隨著數(shù)控技術(shù)、電子技術(shù)等的發(fā)展，組合機床的機械結(jié)構(gòu)和控制系統(tǒng)也發(fā)生了很大的變化。組合機床有了以下的發(fā)展：1. 數(shù)控化。數(shù)控組合機床的出現(xiàn)，不僅改變了過去由繼電器電路組成的組合機床的控制系統(tǒng)，而目也使組合機床機械結(jié)構(gòu)甚至通用部件標(biāo)準(zhǔn)發(fā)生了巨大的變化。2. 模塊化。數(shù)控加
