Some customers will have the gun head automatically adjusted up or down when using the CNC cutting machine, and they can't find out what the reason is. Whether it is CNC flame cutting machine or plasma cutting machine, in the process of using, the lift and movement of the gun is certain. Especially for the cutting of uneven plates, if the cutter gun can not effectively adjust its height, it will certainly lead to the collision of the cutter gun, thus causing damage.
The following is the solution made by DMEC Machinery to the problem that the cutting gun of CNC cutting machine can not be lifted and lowered as follows:
First: check the motor connecting wire poor contact or false welding
Solution: use a multimeter to check and connect the wire
Second: check the button of the connection wire contact or fall off
Solution: Use a multimeter to check and connect the wires.
Third: Check whether the relay for adjusting the lift is damaged.
Solution: If damaged, replace the parts with the same model
In terms of CNC cutting machine faults, there are many times can not be avoided, so you need to have some necessary knowledge of CNC cutting. This is very necessary. During the cutting process, the arc voltage output of the plasma power supply is unstable, which will cause the plasma automatic height adjustment device to work abnormally. In addition, the plasma power supply is generally installed on an arc pressure divider plate, this board if there is a failure, also leading to arc pressure sampling is not correct, which leads to the height adjustment device can not work properly.
Therefore, we must be careful when choosing plasma manufacturers. After-sales service is important.
