Fast wire walking and slow wire walking are differentiated by electrode wire speed

The wire speed of wire bridging is usually around 10m/s, the current cutting speed is generally about 60mm2/min, and the maximum speed is up to more than 200mm2/min; the speed of wire walking is generally lower than 0.25m/s. Its cutting speed is higher than that of fast wire and the precision is better for cutting the workpiece. It is related to the process requirements. It is also related to the machine performance, the material to be processed and the shape, etc. If the surface roughness is not taken, the average processing speed is set to 80 square millimeters. /Minute, then a round bar with a diameter of 50 is cut off, and it takes about 25 minutes to go with the wire. The machine is a wire cutting machine and a wire machine, although it belongs to the wire EDM machine, but due to the difference in the way of wire drawing and the historical reasons The main attack direction is not the same, making the two very different, adapted to different processing areas. "Although there are dual wire system machine tools in the slow walking wire, there are also machine tools that can adjust the wire speed in the wire walking, but they still belong to their respective In terms of structure, neither of them can be realized on the same machine tool.> The wire is usually molybdenum wire or tungsten wire, and can be used repeatedly until breakage. The wire electrode is only one-way through, and it is not used repeatedly.The precision of the wire processing is ±1.5um, usually the wire speed is 300 square MM/min, the roughness is Ra0.1～0.2um, and the diameter of 0.03～0.1MM can be used once Finishing the cold stamping die with concave and convex die and the 0.04MM narrow groove and R0.02 fillet processing, the taper can already exceed the precision processing level of 30 degrees or more. The processing fee is very expensive. "The current processing speed for thread cutting is 0.4. ~0.5 points/mm2, and the processing fee for thread cutting is 10 times faster than thread cutting, ie 4 to 5 points/mm2.
