Of these, drill jigs are, by far, the most common. - 2
A fixture holds the work during machining operations but does not contain special arrangements for guiding the cutting tool, as drill jigs do. 夹具在机加工作业时夹持工件,但它不象钻模那样包含引导切削刀具的特殊布置。 - 3
Jigs make it possible to drill, ream, and tap holes at much greater speeds and with greater accuracy than when the holes are produced by conventional hand methods. 相对于用常规的手工方法加工孔,钻模使得钻孔、铰孔和攻丝速度快很多而且精度更高成为可能。
