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。
机械制造专业英语 PPT课件
Figure 1.8 shows generalpurpose machine tools used for traditional machining in chip removal and abrasion techniques. Typical examples of general-purpose machine tools include turning, drilling, shaping, milling, grinding, broaching, jig boring, and lapping machines intended for specific tasks. Gear cutting and thread cutting are examples of special-purpose machine tools. During the use of general- or special-purpose manual machine tools, product accuracy and productivity depend on the operator’s participation during operation. Capstan and turret lathes are typical machines that somewhat reduce the operator’s role during machining of bar-type or chucking-type WPs at higher rates and better accuracy. Semiautomatic machine tools perform automatically controlled movements, while the WP has to be hand loaded and unloaded. Fully automatic machine tools are those machines in which WP handling and cutting and other auxiliary activities are performed automatically. Semiautomatic and automatic machine tools are best suited for large production lots where the operator’s interference is minimized or completely eliminated, and parts are machined more accurately and economically.

机械专业英语翻译的方法及技巧PPT课件
❖ 1.2 复杂长句多
▪ 机械工程英语的用词和表达方法都比较严谨准确， 一般一句话要包含几个分句。对于这种复杂长句， 一般要采用压缩主干法进行逐步翻译。
▪ If a hard grade wheel was to be used for grinding a hard material ， the dull grains would not be pulled off from the bond quickly enough ， thus impeding the self dressing process of the surface of the wheel and finally resulting in clogging of the wheel and burns on the ground surface ． ( 如果使用硬砂轮磨削硬的材料，磨钝 的磨粒就不能很快从粘结体上脱落，这样便妨碍砂 轮表面的自休整过程，最终导致砂轮的堵塞并在被 磨表面留下灼斑。 )

• Mr. King: Do you have a habit of doing exercise? • Lily: Sure, we have a regulation of morning exercises,
which guarantees us a healthy body. You can meet students undertaking different kinds of exercises if you take a walk in the morning on campus. Mr. King: Would you like to comment on your instructor? Lily: He is a man of profession and responsibility. Whenever you ask him for help, he will always be there without any hesitation.
Mechanical Engineering English
Background
•
The first schools in the United States to offer an engineering education were the United States Military Academy in 1817, an institution now known as Norwich University in 1819, and Rensselaer Polytechnic Institute in 1825. Education in mechanical engineering has historically been based on a strong foundation in mathematics and science; this is followed by courses emphasizing the application of this knowledge and studies in the social sciences and humanities to give the engineer a broader education.
