The spark machine is used to process the mold by electric discharge. According to the requirements of the mold, the current requirement during processing is relatively high. It cannot be too large or too small. However, there are several factors that affect the discharge of the spark machine. Let's take a look at the specific effects.
1. Discharge gap
According to the model, the discharge gap of the single-axis machine is smaller than that of the three-axis machine, because the single-axis spark machine does not shake, and the three-axis machine needs to shake.
This is the place to pay special attention, otherwise the same When working under clearance conditions, a single-axis spark machine is faster than a three-axis spark machine.
2. Slag discharge time
Usually called pulse interval, it is mainly used in conjunction with pulse width, but different brands have different matching methods. Please refer to the instructions for specific conditions.
3. Voltage
Voltage is a very important item, because spark machines are divided into high voltage and low voltage. If the current is large, low voltage can be used, and vice versa.
4. Discharge current
If the current is higher, the surface roughness will be worse. Choose the size of the current on the electrode surface under normal conditions, as well as the projected area of the discharge as the relationship between the discharge gap, and the copper working current is less than 5A/MM2.
5. The longer the discharge time
The longer the discharge time, the longer the working time, but the more carbon deposits will be produced.
6. Other parameters
The detection of abnormal discharge can be adjusted when the discharge state is not good.
