During the machining process of the machine tool, there is a gap between the cut part of the material and the bulk material. If it is not fixed, the material may deform and affect the processing quality. Therefore, like the slow wire processing, paste the connecting copper sheet between the cut part and the bulk material to make the workpiece remain The remaining part is connected and fixed with the body material during cutting to ensure that the wire-cutting machine has good conditions, thereby ensuring the excellent processing quality of the workpiece. This can be carried out according to the following steps. First cut the thin copper sheet (the thickness depends on the electrode wire and the shape of the processed part) into a long strip according to the size of the workpiece, and then fold it, and ensure that the folded part is long and short. The purpose of using the short copper sheet is to reduce the thickness of the copper sheet, and to make the upper nozzle closer to the processing part of the workpiece, so as to improve the processing accuracy, and then flatten the folded part of the copper sheet with a small hand hammer. Then plug the copper sheet treated above into the gap formed by the wire electrode processing, and drip 502 glue (ie, resin instant glue) on the surface of the workpiece. After processing, break it straight to take out the copper sheet from the gap. Attention should be paid here: when using 502 glue to paste and connect the copper piece, keep away from the remaining parts of the workpiece, so as to prevent the 502 glue from leaking into the threading hole of the wire guide just below it, causing the threading hole to block. In addition, symmetrical distribution should be considered for the position of the copper sheet to be pasted and connected, and the plugging should be ensured at the same time to avoid the offset of the workpiece, which will affect the processing quality of the workpiece.
