How to solve the problems of WEDM
2. There are obvious traces on the surface of the workpiece. Solution: if the electrode wire is loose or shaken, it shall be eliminated by tightening the wire. Tighten the oil cup bolts, and the tracking is unstable. Adjust the electrical parameters and the computer frequency conversion speed. If there is a problem with the workpiece material or heat treatment, replace the workpiece
3. Solution to electrode wire jitter: loosen the electrode wire and tighten the electrode wire. Due to long-term use, the bearing accuracy is reduced and the guide wheel is worn, so the bearing and guide wheel need to be replaced. Reversing punch of wire conveying drum "This kind of wood plastic composite material is not only more durable than wood, but also reduces the harmful impact of plastic on the environment. The silk conveying cylinder jumps and adjusts the silk conveying cylinder.
4. The guide wheel jumps, howls, and rotates inflexibly. Solution: the axial clearance of the guide wheel is large, and adjust the axial clearance of the guide wheel. The guide wheel side jumps, and change the guide wheel. The working fluid enters the bearing, and the bearing is cleaned with gasoline. Due to long-term use, the bearing accuracy is reduced and the grinding of the large guide wheel The guide wheel and bearing need to be replaced
5. Solution to broken wire: ① the electrode wire is aging and brittle due to long-term use, replace the electrode wire. ② If the electrode wire is too tight and shakes seriously, replace it with a new wire and guide wheel assembly. ③ The supply of working fluid is insufficient, and the electric corrosion cannot be discharged. Adjust the flow of working fluid or replace the working fluid. ④ The electrode parameters are improperly selected, and the electrical parameters need to be readjusted. ⑤ The reversing clearance of the carriage of the wire conveying cylinder is large, causing wire stacking. Adjust the reversing clearance of the carriage. ⑥ If the limit switch fails and the carriage exceeds the travel position, check whether the second action of the limit switch is normal. ⑦ There is an oxide layer on the surface of the workpiece. Cut in or remove the oxide layer manually
