What should I do if the vacuum suction of the woodworking engraving machine is not strong?

The vacuum suction of the woodworking engraving machine is not strong, and the air leakage problem may occur due to the reduced sealing performance of the vacuum pipe.

If you find such a problem, you can try the following solutions:

1. Check the vacuum pipeline and valve connection to determine whether there is air leakage or uneven working surface.

2. Check whether the motor line voltage is normal, and change the rotation direction of the motor.

3. Check whether the air pump of the water circulation has less water, whether the motor is stuck or rusted, and remove the rotating shaft of the motor fan protection net.

4. Clean the filter plug in the vacuum pump.

5. Add MDF between the work surface and the workpiece.
