在各种玻璃、陶瓷器具上钻孔,这是很棘手的一个问题。用普通麻花钻钻孔,既使不碎也很难打出整齐的孔,用喷砂法、金刚石刀切钻、化学处理等方法,又受各种条件的限制,实施起来也较困难。在此介绍一种简便有效的方法,使用普通钻床或手电钻,加工出整齐美观的孔。一、所需工具、材料 1.根据所需钻孔孔径的大小,选用外径相同的黄铜管或紫铜管,管壁厚1～2mm。将铜管一端锉成一圈60°的小齿,齿高可按h=d/6～d/8计算,式中:h——齿高,d——钻孔直径。
It is a very tricky issue to drill holes in a variety of glass and ceramic appliances. With ordinary twist drill holes, even if not broken it is difficult to play neat holes, with sandblasting method, diamond knife cutting, chemical treatment and other methods, but also by a variety of conditions, the implementation is more difficult. Here is a simple and effective way to use an ordinary drill or hand drill, processing neat and beautiful hole. First, the necessary tools, materials 1. According to the required size of the bore hole diameter, use the same diameter brass or copper tube, the wall thickness of 1 ~ 2mm. The end of the brass file into a circle of 60 ° of small teeth, tooth height can be calculated as h = d / 6 ~ d / 8, where: h - tooth height, d - diameter drilling.
