Faster wire cutting firstly increases cutting tool function than fast wire cutting. The knife dressing is also a multi-knife cutting that we often say. Generally, the first knife is used for cutting, and the next few tools are used to repair the finish. Achievable higher finish.
The electrode wire used for fast wire cutting is used repeatedly. When using the trimming function, as the cutting area is increased, wire drawing and electrode wire loss will occur in the electrode wire, and will become finer and smaller, eventually affecting the accuracy of the work and the subsequent several times of the discharge cutting effect.
In order to obtain high accuracy, it is necessary to measure the actual diameter of the molybdenum wire before starting the cutting. After the new molybdenum wire is cut off the guide line, it is recommended to tightly tighten the molybdenum wire before cutting the workpiece. If the molybdenum wire has been used repeatedly for a long period of time, the diameter and roundness of the molybdenum wire need to be measured. When the difference is too large, a new electrode wire must be replaced.
The following points should also be noted in the multi-cutting of fast wire cutting:
(1) Check the molybdenum wire for jitter when the molybdenum wire is gone.
(2) Whether the surface of the conductive block has a cutting mark or not, and whether the molybdenum wire is trapped in the conductive block.
(3) Whether the working fluid flow and color is normal.
(4) Before processing, the process needs to simulate. Determine whether the cutting program generated by the system is correct.
(5) According to the characteristics of the material, the last cut off of the work remains as long as possible to reduce the effect of material deformation.
(6) Several problems with the work surface after cutting:
1 The surface of the wire is traced, which may be caused by the jitter of the wire or the deformation of the material and the improper setting of the offset.
2 The black spots on both sides of the work surface are serious and the working fluid is problematic. It is recommended to try the BM-4 Water Baseline cutting fluid.
3 After cutting the workpiece, please wash with Oxalic Acid in time, then rinse with water to remove oxalic ACID residue. Wipe the water with a clean white cloth and apply anti-rust oil.
