Analysis of common problems in wire cutting
During the processing operation, it is inevitable that some problems will be encountered. Here are some common problems and causes for reference during operation
There are obvious silk marks on the surface of the workpiece
①The electrode wire is loose or shaken.
②The vertical and horizontal movement of the worktable is unbalanced and the vibration is large.
③Improper adjustment of pulse power parameters.
Shaking silk
①The electrode wire is loose.
②Long-term use of bearings will reduce the accuracy and wear of the guide wheels.
③The impact and the runout of the thread rolling drum increase when the thread rolling drum changes direction.
④The electrode wire is not bent straight.
The guide wheel rotates with a whistling sound, and the rotation is not flexible
①The axial clearance of the guide wheel is large, adjust the axial clearance of the guide wheel.
②The working fluid enters the bearing, clean the bearing with gasoline.
③Long-term use of bearings will reduce the accuracy and wear of the guide wheels. The bearings and guide wheels should be replaced.
Broken wire
① The electrode wire is aging and fragile, and the electrode wire should be replaced.
②The electrode wire is too tight and the wire trembles seriously, the electrode wire should be adjusted.
③ Insufficient supply of working fluid.
④Improper selection of workpiece thickness and electrical parameters.
⑤ If the reversing gap of the carriage of the thread rolling drum is large, the thread breaks, which should be adjusted.
⑥ If the carriage exceeds the stroke position, check the limit switch.
⑦ There is oxide scale on the surface of the workpiece, which should be removed.
⑧ There are non-conductive impurities in the workpiece, and the material should be replaced.
Loose silk
①The electrode wire is installed too loosely.
②The electrode wire has been used for too long and the wire becomes loose, so it should be readjusted.
Burn
①Improper selection of high-frequency power supply electrical parameters.
②The supply of working fluid is insufficient and too dirty, so the fluid supply should be adjusted or replaced.
③The automatic frequency adjustment is not sensitive, so check the control box.
Work accuracy does not match
① If the guide rail is loose, the gap between the lead screw and the nut increases, and it should be adjusted.
②The vertical accuracy of the guide rail does not match and should be adjusted.
③The transmission gear has a large gap and should be adjusted.
④ If the control cabinet fails and the stepper motor fails, repair it.
