1、車床是車間里最有用、最通用的機床之一。它能進行多種機械加工作業(yè)。車床的主要部分是主軸箱、尾座和刀架。主軸箱與尾座位于床身的兩端；用于夾持刀具的刀架置于主軸箱與尾座之間。刀架安裝在中托板上，根據(jù)加工的種類，中托板使刀架既能橫向運動，又能與床鞍一起作縱向運動。普通頂尖車床在刀架上一次只能安裝一把刀具，而在轉(zhuǎn)塔車床的轉(zhuǎn)塔刀架上可同時夾持五把或更多的刀具。車床床身必須非常堅固，以防在應力作用下產(chǎn)生彎曲或扭轉(zhuǎn)變形。 主軸箱內(nèi)裝有驅(qū)動裝置與齒輪機構(gòu)，以及夾持工具并使其旋轉(zhuǎn)的主軸。工件轉(zhuǎn)速很大程度上取決于工件。

17、1 附 錄 A 數(shù)控車床作為普通車床的替代品，已經(jīng)開始普及，但是對于數(shù)控車加工的工藝裝備和參數(shù)設定往往還有依靠經(jīng)驗給出的情況，這對于發(fā)揮數(shù)控高效率工作并無益處。 數(shù)控車床加工的工藝與普通車床的加工工藝類似，但由于數(shù)控車床是一次裝夾，連續(xù)自動加工完成所有車削工序，因而應注意以下幾個方面。 1、合理選擇切削用量 對于高效率的金屬切削加工來說，被加工材料、切削工具、切削條件是三大要素。這些決定著加工時間、刀具壽命和加工質(zhì)量。經(jīng)濟有效的加工方式必然 是合理的選擇了切削條件。切削條件的三要素：切削速度、進給量和切深。
