Common problems and solutions of CNC engraving machine

As a high-tech material, CNC engraving machine will inevitably have faults in the process of use, but how to deal with the faults. Introduce in detail the solutions to the five common faults of CNC engraving machines. Let's learn about the common problems and solutions of CNC engraving machines.

Common problems and solutions of CNC engraving machine

Common fault one: CNC engraving machine alarm common faults.

The overtravel alarm indicates that the CNC engraving machine has exceeded the limit position during the operation process, and check it according to the following procedures.

1. Is the graphic specification of the design concept beyond the scope of production and processing, for example, if you are a professional advertising engraving machine, you cannot use it to process thick metal plates, no problem;

2. Check whether the connecting wire between the motor shaft of the CNC engraving machine and the electrode of the ball screw is loose, if so, please tighten the screw;

3. Whether the CNC engraving machine and the computer are properly grounded;

4. Does the current coordinate value exceed the range of the software limit switch value?

Common fault two: CNC engraving machine overtravel alarm and elimination

1. All motion axes are automatically set in the start-up light state. As long as the manual arrow key is pressed all the time, the connection motion state can be restored at any time when the device leaves the limit position (that is, the over-travel point switch is released);

2. Pay attention to the direction of movement when moving the console, and be sure to stay away from the limit.

Common fault three: CNC engraving machine has no alarm fault

1. Insufficient repetitive processing accuracy, check according to Item 2 of Article 1;

2. When the computer is running and the machine is not moving, check whether the connection between the computer control card and the electrical box is loose. If yes, insert and tighten set screw. Imported pump valve industrial washing machine;

3. The CNC engraving machine cannot find the signal when returning to the mechanical origin, check according to item 2. The proximity switch at the mechanical origin is out of order.

Common fault four: CNC engraving machine output fault

1. There is no output, please check whether the connection between the computer and the control box is correct;

2. Open whether the space in the engraving manager settings is full, and delete unused files in the manager;

3. Check whether the signal line wiring is loose, and carefully check whether all lines are connected;

The above is the entire content of the common problems of CNC engraving machines. I hope this article can be helpful to everyone.
