6、铣削主要两种方式：逆铣（常规）和顺铣（同向）。逆铣时，铣刀的旋转方向与工件的进给方向相反。也就是说，在逆铣过程中，如果刀具顺时针旋转，则工件向右移动进给。顺铣时，铣刀顺着进给方向旋转。换句话说就是在顺铣过程中，如果刀具逆时针旋转，则工件向右移动进给。There are two main methods of milling:up or convertional milling （逆） and down or climb milling（顺）.In up milling, the cutter rotates against the direction of feed.That is to sa
7、y, if the cutter rotates clockwise,the workpiece is fed to theright in this kind of milling.In down milling,the cutter rotates in the direction of feed.In other words,if the cutter rotates counterclockwise, the workpiece is fed to the right in down milling.2、顺铣具有以下优点：进给量通常可达到逆铣两倍以上；快速切削金属而不产生振动；大幅度降
8、低工件表面粗糙度；延长刀具的使用寿命。The advantages of down milling are as follows:Feed can frequently be doubled over up milling.Metals can be removed fast without vibration.Finish can be considerably improved.Tool life may be prolonged.3、铣床用旋转的铣刀来切削各种形状的工件。卧式铣床主要构成部分如下：床身，主轴，刀杆，横梁，工作台，床鞍，升降台，底座，电机等。The milling mach
9、ine cuts various shapes with rotary cutters.The horizontal machine consists of the following important parts: column , spindle, arbor, overarm, table, saddle, knee, base,motor,etc.4、钻削加工可以用便携式的小机器或适当的机床来进行。尽管它们有相同的特征，后者在形状和尺寸上有不同。例如，它们都包含一个或更多的麻花钻，当工件被牢固地夹紧时绕着自身的轴线旋转。Drilling operations can be carri
10、ed out by employing either portable small machines or appropriate machine tools. The latter differ in shape and size, although they have common features. For instance, they all involve one or more twist drills, each rotating around its own axis while the workpiece is kept firmly fixed.5、这与在车床上进行的钻孔操
11、作正好相反，车床上，工件被夹紧在夹具内并随其转动。以下是常用类型钻床的情况。This is contrary to the drilling operation on a lathe, where the workpiece isheld in and rotates with the chuck. Following is a survey of the commonly used types of drilling machines.6、根据尺寸，立式钻床能用于加工轻的、中等的甚至是相对重型的工件。它与台式钻床基本类似，主要的区别之处在于一根较长的固定在底座上的圆形立柱。Depending
12、 upon the size, upright drilling machine tools can be used for light, medium, and even relatively heavy jobs. It is basically similar to bench-type machines,the main difference being a longer cylindrical column fixed to the base.7、沿着立柱是一个附加的安装工件的滑动工作台，它能在任何需要高度锁定位置。这种钻床所需的功率比台式钻床要大，因为它用于做中等负荷的工作。Alo
13、ng that column is an additional, sliding table for fixing the workpiece which can be locked in position at any desired height. The power required for this type is more than that for the bench-type drilling machines, since this type is employed in performing medium-duty jobs.8、台式钻床是通用的小型机床，通常放置在工作台上。
14、这种钻床用电机作为动力源，通过皮带轮和带将动力传输到装有刀具的主轴上。Bench-type Drilling Machines Bench-type drilling machines are general-purpose, small machine tools that are usually placed on benches. This type of drilling machine includes an electric motor as the source of motion, which is transmitted via pulleys and belts to the spindle, where th
