The spark machine is a processing tool, but abnormal phenomena will appear after a long time of operation. Of course, we can also make corresponding adjustments according to different conditions.
Today, I will tell you a few ways to distinguish the abnormal spark machine.
- 1. Look: This means to look at the current. The current and voltmeter of the ordinary electric spark machine are in a regular swing state, and the servo dial indicator is fed at a constant speed at an appropriate position. When the discharge is unstable, the current and voltmeter have obvious swings, processing does not proceed, the head is running on the top, and the servo scale indicator jumps quickly.
- 2. Listen: the color of the normal electric discharge machining sparks is blue-white folder red, take small bubbles of smokeless treatment liquid, and hear the sparks with crisp sound. When the spark discharge becomes unstable, the color part is bright red and white bubbles with a large smoke level.
- 3. Look: In the normal EDM process, the depth detection value will rise steadily. Even if it is deeper, its deep processing depth will differ from the current value by 1 wire. When the flow is unstable, the depth detection value will vary greatly. , Showing a reciprocating state.
- 4. Experience: In addition to the performance of the mirror spark machine, the main experience is still very important, especially in terms of coolant. Some customers buy the spark machine of poor quality, although it is cheap but does not have a cooling effect, processing is slow, and causes carbon accumulation.
