SCX—73型线切割机床有很多优点,但在使用中我们发现有个小缺点。该机床的高频电源与碳刷的接线容易断,经常毫无必要增加维修量。原因就是每取一次碳刷就要把这个碳刷来回旋转很多次,而接线是焊在里面的,故易断。现在我们在碳刷胶木座上加了一只香焦插,把高频接线焊在香焦插头上就解决了这个问题,如下图,很简单实用。 SCX-73 wire-cutting machine has many advantages, but in use we found a minor drawback. The machine’s high-frequency power and carbon brush wiring easy to break, often no need to increase the amount of maintenance. The reason is that every time you take a carbon brush to rotate the carbon brush back and forth many times, and the wiring is welded in it, it is easy to break. Now we add a brush in the bakelite bakelite incense plug, the high-frequency wiring soldered in the incense burner to solve this problem, as shown below, very simple and practical.
