How to improve the wear of tungsten steel conductive blocks?
Release time:
2023-05-26
One: Requirements for working fluids The current aqueous solution used as the working fluid for CNC high-speed wire walking EDM tungsten steel conductive block wire cutting processing, with a conventional configuration of 1.10 and processing aluminum material of 3.8. To maintain the cleanliness of the working fluid and ensure its effective operation, the sponge after use can avoid flowing into the water tank, maintain the smoothness of the working fluid, and reduce adhesion. Sponge is regularly changed and washed. Secondly, the reasonable combination of pulse electrical parameters When CNC high-speed wire EDM machining of tungsten steel conductive blocks, a wider pulse width is prone to producing larger alumina or surface adhered alumina particles, and a smaller pulse interval can also produce larger particles. However, electrode wires are prone to adhering to these larger machining particles, which has a significant negative impact on machining. By increasing the no-load voltage value of the pulse current, reducing the pulse width, and increasing the pulse gap, the possibility of sticking to the electrode wire can be reduced. Thirdly, operational skills A sponge can be added to the rear slot of the wire rack, and the high-speed reciprocating electrode wire is rubbed by the sponge to reduce electrode wire shaking and ensure the normal operation of the tungsten steel conductive block power supply.
