cnc wire cut edm machine manufacturers

The premise of stable cutting in the wire-moving machine tool must ensure that the wire is cut during the cutting process. The breakage rate increases as the discharge energy and the cut thickness increase, and is related to the residence time, cooling state, and ion bombardment of the wire in the discharge channel. Cutting efficiency and surface roughness are related to deionization and restoration of insulation.

In the wire moving machine tool, since there is no guarantee that there is an updated working medium between the two poles, this will directly affect the continuation of normal discharges, even discharges in the gaps mixed with a large amount of colloidal substances, and even arc discharges, so that the workpiece and wire surface Without timely cooling, the insulation state is not normal, causing the normal discharge ratio to decrease, the cutting speed to be reduced, the surface of the workpiece to be burned, the commutation streaks to be severe and the processing quality deteriorated, and at the same time, the electrode wire is damaged, and the wire is severely burned.

Therefore, the use of emulsion as the working medium has a greater impact on the improvement of the cooling state in the inter-channel channels, deionization, and restoration of the insulation state. The higher the workpiece, the slower the wire speed, and the longer the electrode wire stays in the processing zone. The probability of broken wires naturally increases. It is an inevitable phenomenon that the emulsion decomposes into colloidal or particulate matter in the discharge channel.
