1. When the CNC foam cutting machine cuts thick parts, if the Hangzhou foam machinery interval is too small, or use the working fluid that is not suitable for cutting thick parts;
2. The performance of the clipping diode of the pulse power supply deteriorates, and the negative wave in the CNC foam cutting machine is relatively large, which increases the loss of the molybdenum wire in a short time;
3. The quality of the heating wire is poor or the storage is not good, resulting in oxidation, or the wire is stretched with an inappropriate tool such as a small iron rod when feeding the wire, causing damage to the wire;
4. The rotating speed of the heating wire drum is too slow, so that the molybdenum wire stays in the working area for too long;
5. Improper selection of the diameter of the heating wire when cutting the workpiece.
6. Select the motor current is too large;
7. The conductive block is not in contact with the heating wire or has been pulled out of the dent by the molybdenum wire, resulting in poor contact. The CNC foam cutting machine has a stroke protection function. When the movement stroke exceeds the specified stroke, the equipment will automatically protect and stop. In addition, Changlin CNC foam cutting machine also has the functions of power-off memory, reverse cutting and rotation, mirror symmetry, and infinite return.
