Lathe and Its Parts
The bed is a long part to the left end of which the headstock is fastened. while the tailstock can be clamped to any other part of the bed. The carriage is the part which slides on the v-shaped ways along the bed between the headstock and the tailstock. Each lathe is now generally run by a separate electric motor. Lathe sizes range from very little lathes with the length of the bed in several inches to very largest ones turning a work many feet in length. The size of a lathe is measured by :1)the largest diameter of work that can be turned in the lathe;2)the length of bed. Thus, a 10”*5ft. (10 inch*5 feet) lathe can turn a work of 10 inch in diameter and five feet long.
Different metals must be cut at different speeds. Soft metals should be cut with greater speed than hard metals. A coarse cut should beslower than a finish cut. A large piece should be run more slowly than a piece with a small diameter. By using the mechanism called gear box different speeds may be obtained suitable for different conditions of work.
Lathe Chucks
A lathe chuck is used for holding the work. It should be screwed on the headstock spindle while the lathe is stopped. There are two kinds of lathe chucks: the four-jaws independent chuck and the three-jaw universal chuck. The four-jaw independent chuck has four jaws and each jaw has to be moved separately by turning the screw of the jaw; it is mostly used to hold a work that is not perfectly round. The jaw on this kind of chuck can be taken off and put on again in the opposite direction.
In the three-jaw universal chuck all jaws work at the same time. Thus, by screwing down one jaw we make the other two jaws move on the work placed in the center of the chuck.
Chucking means fastening the work in a lathe chuck so that it might turn without wobbling. 展开

车床及其配件
这床是一个漫长的一部分,其中左端主轴箱是否牢固。而尾座可以夹紧任何床的另一部分。马车是沿线部分之间的车头和车尾床的V形方法的幻灯片。每个车床现在一般由一个独立的电动马达。车床的尺寸范围从床的长度在几英寸的小车床非常非常大的转折点,许多英尺长的工作。该车床的大小是衡量:1)工作的最大直径可在车床转化; 2)床的长度。因此,10“*5英尺(5英尺10英寸*)车床可以打开一个直径为10英寸和5英尺长的工作。
不同的金属必须削减速度不同。软金属应削减大于硬质金属的速度。一个粗糙的切割应beslower比完成削减。一大块应运行速度比一小直径作品。通过使用不同的机制,称为齿轮箱的速度可能会获得不同的工作条件适宜。
车床夹头
车床卡盘用于举行的工作。应拧上的车床主轴箱主轴而停止。有两种类型的车床夹头:四爪卡盘和独立三爪卡盘普遍。四爪卡盘有四个独立的嘴巴和下巴每个单独要搬转动螺丝的下巴,它主要是用来存放一个工作,是不完美的圆形。关于这一类的卡盘爪可以被取下,放在相反的方向了。
在三爪卡盘普遍都在同一时间颌骨工作。因此,通过一个下巴拧下来让我们在其他两个爪卡盘中心的工作置于移动。
夹持方式紧固在车床卡盘的工作,以便它可能会将不抖动
