常用的机床类型有：
一、车床
按其主轴水平放置还是竖直放置可分为：卧式车床和立式车床。车床的主要组成部分有：主轴箱、刀架、尾座、进给箱、溜板箱和床身。车床上能完成的工作有：车圆柱、车圆锥、车成型面、车外槽、车端面、用成型刀切削、镗内槽、钻孔、切断、车螺纹等等。
二、铣床
铣床的主要组成部分有：悬梁、心轴、立柱、工作台、溜板、升降台和床身。铣床上能完成的工作有：铣平面、铣端面。此外还可以铣螺旋槽，所以可以制造铣刀、螺旋齿轮、麻花钻和螺旋蜗杆等等。
三、钻床
钻床用来钻孔、攻螺纹、铰孔以及小尺寸的镗孔操作。
四、磨床
磨床的刀具是砂轮。磨床上能完成的工作有：磨平面、磨圆柱、磨内圆等等。
常用的加工方法有：车削、铣削、钻削和磨削。此外，还有焊接、电火花加工、激光加工等。

Commonly used in metal processing methods and tools
Machine tool commonly used types are:
First, lathe
Its axis horizontal or vertical placement can be divided into: horizontal and vertical lathe lathe. The main component of the lathe: Spindle Box, Tool, Tailstock, feed me, and the crate slipped bed. Lathe to complete the work are: cylinder cars, trucks cone, forming surface vehicles, slot cars, trucks face with a knife cutting shape, with slot boring, drilling, cutting, thread cars and so on.
Second, the milling machine
The main components of the machine are: cantilever, spindle, column, table, slipped boards, and the lifting platform bed. Milling on the completion of the work: flat milling, end milling. In addition to milling trough Spiral, so manufacturer can cutter, spiral gears, twist and spiral worm, and so on.
Third, drilling
Borehole drilling machine used to attack screw, hinge, as well as small size of the hole boring operation.
