Causes of Wire Breakage of CNC Cutting Machine

Causes of wire breakage of CNC cutting machine:
1. Improper selection of electrical parameters and excessive current;
2. Improper feed adjustment, slow and slow, frequent open circuit and short circuit:
3. The conductive block is not in contact with the heating wire or has been pulled out of the dent by the heating wire, which will cause poor contact:
4. When cutting parts, the running speed is not too slow or the workpiece has residue:
5. The performance of the clipping diode of the pulse power supply deteriorates, and the negative wave is large during processing, which increases the loss of molybdenum wire in a short time
6. Poor quality of molybdenum wire or improper storage will cause oxidation, or use small iron rods and other inappropriate tools to stretch the wire when the wire is loaded, causing damage to the wire:
7. The rotation speed of the wire storage drum is too slow, so that the molybdenum wire stays in the working area for too long
8. Improper selection of molybdenum wire diameter when cutting the workpiece.
