Similarities:

1. The working principle is the same. Both of them dissolve metal by high temperature generated by discharge.

2. The surface roughness is similar to the productivity of the machine tool and can process all conductive materials.

3. Both of them have different restrictions on the minimum angular radius.

difference:

1. EDM is to make spark lines on the machined workpiece, while wire cutting is to discharge the workpiece and cut it into shape.

2. EDM must first manufacture the electrode of the shape to be machined through other NC machine tools. Wire cutting processes the contour of the workpiece through the movement of the workbench and molybdenum wire.

3. The spark machine can process beautiful spark lines; Wire cutting can process small holes and complicated seams.

4. The electrode of spark machine is easy to lose, so it is often processed with multiple electrodes; Wire cutting will automatically replace the damaged electrode wire in the machining process, so there is no problem that the electrode damage affects the machining accuracy.
