What are the main factors that affect Wire EDM Parts?

During the production process, Wire EDM Parts are also affected by some external factors. So, what are the main factors influencing wire cutting processing? Let Xincheng Precision introduce them for you.

The factors influencing wire cutting processing are as follows:

1.The cutting path of the slow wire cutting process is properly arranged

This guidance method aims to avoid disrupting the original internal stress balance of the workpiece material. It also prevents significant deformation of the workpiece during the cutting process due to the influence of fixtures and other factors, and avoids a decline in the surface quality of the cut.

2. Fixation of the processed workpiece

After the processing of the workpiece is completed and it is cut, the connection strength between the processed workpiece and the raw material will decrease. At this time, it is necessary to avoid the processing fluid's impact causing the processed workpiece to tilt. Once the tilt occurs, it will lead to a change in the cutting gap. In the mild case, it will affect the surface quality of the workpiece; in the severe case, it will cause the workpiece to be damaged and scrapped. Therefore, it is very important to fix the processed workpiece properly.

3. During the processing, the principle of small quantities and multiple batches is adopted

During the processing, the processing volume is generally determined by the processing parameters of the machine tool. Based on previous processing experience, except for the first processing, the processing volume generally decreases from several micrometers to a few micrometers. The processing volume should be reduced, and the more processing times, the better the surface quality of the workpiece. Since reducing the deformation of the material during wire cutting processing can improve the surface quality of the workpiece, a method of small amounts and multiple cuts is adopted.

During rough processing or semi-finishing, a certain amount of allowance can be left to compensate for the machining allowance required during fine processing due to the disruption of the original stress balance of the material.

4. Correctly select the cutting parameters

For different rough and finish machining processes, the cutting parameters should be adjusted accordingly, including: wire speed, wire tension, and jet pressure, etc. To ensure that the machined workpiece has higher precision and surface quality, appropriately increasing the wire speed and wire tension of the wire-cutting machine will have a very good effect. Although some equipment has certain cutting condition matching parameters, due to the influence of the material of the workpiece, the required machining accuracy, and other factors, the operator needs to adjust the parameters based on the actual situation.

5. Adopt close-distance processing

In order to achieve the required precision and surface quality of the workpiece, lapping processing can be adopted in actual production, so that the distance between the upper nozzle and the workpiece can be made as close as possible. This can avoid the situation where the distance between the nozzle and the workpiece affects the surface quality of the workpiece.
