Wire cutting tension?

The tension of WEDM in WEDM refers to the tension of electrode wire during cutting. If the tension is too small, the electrode wire will be deformed or broken during cutting. Excessive tension will lead to the vibration of electrode wire during cutting and affect the cutting accuracy.

When WEDM starts cutting, if the tension of the electrode wire is too small, it will lead to a short circuit between the electrode wire and the workpiece, which will affect the cutting effect. At this point, it is necessary to adjust the tension of the electrode wire until the short circuit disappears.

If you forget to adjust the original tension after reducing the tension of the electrode wire and cut it directly for three times, it may cause the electrode wire to break or reduce the cutting accuracy. Therefore, in the cutting process of WEDM, it is necessary to pay attention to the tension of the electrode wire, check the wear of the electrode wire regularly, and replace the electrode wire in time.

The following are several methods to adjust the tension of WEDM electrode wire:

Use a tensiometer to measure the tension of the electrode wire.

Adjust the tension of the electrode wire by adjusting the tension wheel.

In the process of cutting, check the tension of electrode wire regularly and adjust it as needed.
