1.There are two kinds of gun drills, namely, the center-cut gun drill used for drilling blind holes and the trepanning drill.
深孔钻分为两种，即用于钻削盲孔的中心钻和套孔 钻。
另一方面，直柄钻被固定到钻夹中，同理， 钻夹以与锥柄钻相同的方式固定到主轴孔中。
Paragraph 5
1.Twist drills are usually made of high-speed steel, although carbide-tipped drills are also available. The size of twist drills used in industrial range from 0.01 up to 3.25 in. (i.e., 0.25 up to 80 mm).
钻是利用绕轴旋转的钻头在工件上生成通孔或盲 孔的加工工艺。
2.Consequently, the range of cutting from that axis of rotation is equal to the radius of required hole.
因此，旋转轴的切削范围就等于所钻孔的半径。
2.This type of drill may have either three or four flutes and equal number of margins, which ensure superior guidance, thus resulting in high machining accuracy.这种类型的钻具有三个或四个出屑槽以及 相同数量的刃带，这些可确保准确的导向，从而获 得较高的机加工精度。

But all this extra hardware is costly and needs maintaince. In the last decade, as speed requirements have risen the inaccuracy caused by vibration, which was not a problem at lower speed, made the complex mechanical transmission unacceptable for some applications.

Paragraph 2:
The Basic
All electric motors use the principle that like magnetic poles repel and unlike poles attract. Current through a coil or permanent magnets creates magnetic fields . 所有电机都遵循磁极同极相斥，异极相吸的原 理。电流通过线圈或永久磁铁时产生磁场。
4
Motors deliver torque by shifting the magnetic fields within the motor, so the rotor is constantly drawn around.
5
Paragraph 3:
Initially, all motors used direct current (DC). This current creates magnetic fields in the stator and rotor, then mechanically energizing and de-energizing stator coils cause a moving field that draws the rotor around.
