When the aluminum wire cutting machine tool is used to process aluminum materials, the conductive blocks are particularly worn, and deep grooves are formed on the conductive blocks. Aluminum material is a common metal used in production and processing, and will not be abandoned. Therefore, we must solve this important problem. Let's see where it should be handled.

1. Reasonable matching of pulse electrical parameters: When the wire cutting process is used, the wider pulse width is easy to produce larger alumina or particles with alumina on the surface. If the pulse interval is too small, a large pull will be generated. . On the molybdenum wire, it is easy to adhere to these large processed particles, which has a great negative impact on the processing. Increasing the no-load voltage amplitude of the pulse power supply can reduce the possibility of the processing debris being attached to the wire by reducing the pulse width and processing the pulse gap.

2. Requirements for working fluid: At present, the aqueous solution is often used as the working fluid for the middle wire cutting process. The conventional configuration ratio of the BMW is 1:30, and when processing the aluminum material, the ratio of 3:8 should be adopted. In order to keep the working fluid clean, to work normally and effectively, and to extend the service life of the working fluid, a thick sponge can be used to prevent the debris from flowing into the water tank, keeping the working fluid unblocked and reducing the stickiness of the machining chips on the wire. Attached. Regularly clean or replace the sponge pad. The amount of water sprayed on the upper and lower sides of the working fluid should be uniform so as to eliminate the corrosion in time.

3. Operational skills: a sponge can be added to the rear end slot of the upper frame. The high-speed reciprocating electrode wire is rubbed by the sponge to remove some of the adhered oxide, reduce the wear of the oxide on the conductive block, and reduce the wire jitter. Ensure that the pulse power supply efficiency is functioning properly. Also pay attention to the working position of the replacement of the conductive block.

The above method is not only suitable for cutting aluminum materials, but also for the processing of some special materials, such as conductive ceramics, silicon nitride and boron nitride. If the wire cutting machine in the electric spark is used for processing large quantities of aluminum parts, the processing problem will be more prominent. The above measures cannot solve the problem fundamentally. This requires no consideration from the perspective of machine tool transformation. The way of block feeding, such as the way of feeding the wire, can be applied to production and processing.
