How to prevent the rusting of the WEDM-LS workpiece

We often find that the WEDM-LS workpiece is prone to rust, which is because the working fluid used in the processing is deionized water, which can easily lead to the work piece to be embroidered. So, how do we prevent the WEDM-LS workpiece from rusting? First of all, it is best to apply rust-proof oil to the workpiece that has been cut and exposed to the outside if the long cutting time is slow; If a blank has been clamped on the workbench for a long time, the next day when used, apply compressed air to dry the water on the workpiece before work.;The cut parts first dry the water on the workpiece and then spray with antirust oil; If there is a sandblasting machine, the surface can be treated by sandblasting. If there is no sandblasting machine, it can be dipped with weak acid, then rinsed with clear water and quickly dried with oil; Now there is a special antirust liquid, added in water, can inhibit the corrosion of the workpiece. Using these methods, no longer afraid of the WEDM-LS workpiece rust. Can also greatly improve the processing efficiency of WEDM-LS.
