On the process of wire cutting, how to deal with wire cut power feed contacts excessive wear? KENOS help you to solve this problem. KENOS is a professional wire cut feed power contacts manufacturers, who has the most outstanding wire cut power feed contacts expert, so we will be able to give you a satisfactory answer. Let’s explore solutions of wire cut power feed contacts excessive wear.
Firstly, pulse with a reasonable parameters: while CNC EDM fast wire cut processing, the wider pulse is easy to produce a relatively large aluminum oxide or some sticky alumina oxide particles. If there is small pulse interval, it also will produce larger particles. And the wire will easily adhere to these larger particles, which will bring a great deal of negative impact to process. By increasing the load voltage of the pulse current and the pulse interval, in the same time reduce the pulse width, it will reduce the possibility of particles to stick in the electrode wire.
Secondly, the requirements of the working fluid: currently the general configuration of CNC high speed wire EDM wire cut fluid is 1:10, and machined aluminum material is 3:8. Keeping the work water clean can keep effective work. Used sponge avoid water inflow to tank, maintain the smooth flow of the working fluid, which can reduce adhesion. So sponge must be washed regularly.
Thirdly, operating skills: You can plus a back-end bath sponge on the wire shelf, which can reduce the shake of wire to ensure the normal function of wire cut power feed contacts, when the high-speed electrode wire rub with sponge.
Fourthly, on the canister plus one wire tube brush to filter out cutting molybdenum wire are glued to the aluminum dross, so that the wire cut power feed contacts wear will be controlled in the normal range.
When high speed wire EDM machining aluminum, as aluminum own characteristics is difficult to process, resulting the wire cut power feed contacts worn badly. Kenos has show you three method to solve the problem of wire cut power feed contacts excessive wear, I hope you will like it.
