手工钻孔是钳工的一项基本技能,该方法简单易操作应用较为广泛,钳工手工钻孔就是利用台钻对装夹在可移动的虎钳上的工件进行钻孔。手工钻孔主要用于对孔精度要求不高的场合,用该方法钻出的孔精度可达到大约0.2mm以上,钻孔的精度与钻孔方法与钻孔熟练程度有着较大的关系。
Manual drilling is a basic skill of fitter. The method is simple and easy to operate and is widely used. Manual hole drilling is the use of a bench drill to drill a workpiece that is mounted on a movable vise. Manual drilling is mainly used for the hole less demanding accuracy of the hole drilling accuracy of this method can reach about 0.2mm above the drilling accuracy and drilling methods and drilling proficiency have a greater relationship.
