直径极小的深孔是不能用目前钻削的方法加工出来的。为此,美国一家公可创造了一种新的制孔工艺。其方法与普通钻孔法相反,它不在金属上钻孔,而在孔的周围浇注金属。采用这种工艺,可加工出直径0.125毫米,长度63.5毫来的超小深孔。其具体步骤如下:在一个框架上拉紧一根金属丝,金属丝的直径须与被加工的孔径一样。先在金属丝上镀一层铬,再镀一层镍,镀完后,把它拿去腐蚀,只把中间的金属腐蚀掉,而镀层被保留下来,镀层内部就形成了深
Deep holes with very small diameters can not be machined with the current method of drilling. To this end, the United States a public can create a new hole making process. The method is the opposite of the normal drilling method, which does not drill holes in the metal, but pouring metal around the holes. Using this process, ultra-small deep holes with a diameter of 0.125 mm and a length of 63.5 millimeters can be machined. The specific steps are as follows: Tighten a wire in a frame, the diameter of the wire to be machined with the same aperture. The first wire coated with a layer of chromium, and then a layer of nickel plated, after plating, take it to corrosion, only the middle of the metal corrosion, and the coating is retained, the coating is formed deep inside
