附录1
英文原文
Lathes are widely used in industry to produce all kinds of machined parts. Some are general purpose machines, and others are used to perform highly specialized operations.
Engine Lathes
Engine lathes, of course, are general-purpose machine used in production and maintenance shop all over the world. Sizes range from small bench models to huge heavy duty pieces of equipment. Many of the larger lathes come equipped with attachments not commonly found in the ordinary shop, such as automatic stops for the carriage.
Tracer or Duplicating Lathes
The tracer or duplicating lathe is designed to produce irregularly shaped parts automatically. The basic operation of this lathe is as fallows. A template of either a flat or three-dimensional shape is placed in a holder. A guide or pointer then moves along this shape and its movement controls that of the cutting tool. The duplication may include a square or tapered shoulder, grooves, tapers, and contours. Work such as motor shafts, spindles, pistons, rods, car axles, turbine shafts, and a variety of other objects can be turned using this type of lathe.
Turret Lathes
When machining a complex workpiece on a general-purpose lathe, a great deal of time is spent changing and adjusting the several tools that are needed to complete the work. One of the first adaptations of the engine lathe which made it more suitable to mass production was the addition of multi-tool turret in place of the tailstock. Although most turrets have six stations, some have as many as eight.
High-production turret lathes are very complicated machines with a wide variety of power accessories. The principal feature of all turret lathes, however, is that the tools can perform a consecutive serials of operations in proper sequence. Once the tools have been set and adjusted, little skill is required to run out duplicate parts.

车 床
车床在工业生产中被广泛用来加工各种类型的机械零件。一些车床是通用机床,而另一些车床则被用来完成某些专门工序的加工任务。
普通车床
普通车床是全世界的生产车间和维修车间里广泛使用的通用机床。它的尺寸范围很广,从小型的台式车床到巨大的重型车床。许多大型的车床配备在普通车间中通常看不到的附件,例如,滑板的自动挡块。
靠模车床或仿形车床
靠模车床或仿形车床被设计用来对形状不规则的零件进行自动加工。这种车床的基本操作如下:在夹持装置上安装平面或立体形状的样板,然后,导向触头或指针沿着它的外形移动,从而控制切削刀具的运动。仿形加工可以包括方形或锥形轴肩、各种槽、锥体和轮廓。像电动机的轴、主轴、活塞、杆件、汽车轴、汽轮机轴和其他很多种类的工件都可以采用这种车床来进行切削加工。
转塔车床
在通用车床上加工一个复杂的工件时,在更换和调整加工时所用的一些刀具上要花费很多时间。对普通车床的早期改装工作之一是增加一个可以安装多把刀具的转塔来代替尾架,使它能够更好地适应大批量生产的需要。虽然大多数转塔有六个工位,但有些转塔有八个工位。
高生产率的转塔车床是装有许多动力附件的非常复杂的机器。然而,所有转塔车床的主要特点是刀具能按适当顺序完成一系列的加工工序。一旦这些刀具被安装调整好后,只需要很低的技术就可车削加工很多相同的零件。
自动螺丝车床
螺丝车床在结构上与转塔车床类似,不同之处是螺丝车床的主轴头部能被设计用来夹持和送进长棒料。除此之外,它们之间几乎没有什么差别。这两种车床都用于多刀具切削,都适合加工同样的工件。最初,为转塔车床设计的用途和卡盘车床的用途一样,也是用来加工小型铸件、锻件和形状不规则的零件。早期的螺丝车床通过棒料和线材的送进,制造小的螺丝零件。时至今日,转塔车床上经常使用夹头附件,而自动螺丝车床上则可通过安装卡盘用来夹持铸件。
