求一段机械专业英语翻译

The milling cutters aregenerally made from high speed steel and are available in different sizes andshapes. There are such kinds of milling cutters as cylindrical cutters, endmilling cutters (for face milling), form milling cutters, angular cutters ,side and face cutters, slitting saw, etc. These cutters may differ in thedirection of their operation, i.e, they may cut revolving either clockwise orcounter-clockwise。
Regular or irregular shapedwork may be produced on a milling machine, designs varying according to theparticular class of work wanted. According to the position of the spindle, themilling machines may be divided into two groups of vertical spindle millingmachines and horizontal spindle milling machines. Milling machines may begrouped into various classes.
According to the variationin general design as the “column and knee type”, the manufacturing types, andthe planner type of milling machine. According to the table design, the millingmachines may be classified as universal and plain milling machines.
The most important parts ofthe milling machine are starting levers, spindle, column, knee, elevatingscrew, table, index head, speed levers, feed levers, table movement levers,foot stock, arbor yoke.

Answer 1

这个铣刀是由高速钢制成的而且这个系列的铣刀有不同的大小和形状可供选择。这一系列的刀有包括圆柱形铣刀、端铣削铣刀（用来端面铣）、成型铣刀、 斜角铣刀、边面刀、槽刀等在内的刀。这些刀在走刀方向上可能有些不同。比如：有些是顺时针切割，还有些是逆时针切割。

规则和不规则的形状加工可能会被安排在一个铣床上加工，加工设计根据你想要的不同种类的成品来决定。根据主轴的位置，铣床可以被分为2个系列的立式铣床和卧式铣床。但是铣床还可以分为很多种。

根据变化的总体设计比如“升降式”，一种加工制造种类，而且铣床的种类（这句没怎么看懂= =）。再根据表格设计，铣床就可以被分为万能铣床和普通铣床。

铣床最重要的部分是开始杠杆，主轴，床身，升降台，升降丝杆，工作台面，分度头，转速杠杆，进给速度杠杆，工作台面移动杠杆，尾座，刀杆座。

铣刀基本由高速钢制成，并且做成各种尺寸和形状。比如有圆柱形铣刀、端部铣刀（用于铣表面）、成型铣刀、角铣刀、侧面与表面铣刀、拉刀等。这些铣刀在工作中可以改变方向，比如可以顺时针或者逆时针旋转切削。
在铣床上可以加工规则或者不规则形状的工件，根据所需工件的不同等级加以涉及更改。
