Troubleshooting of CNC engraving and milling machine and how to repair it

Many people ask me how much is the CNC engraving and milling machine for imported engraving machines? However, the repair and use of the machine has been ignored. Here is how to solve the problem of the machine.

First, the spindle of the CNC numerical control engraving and milling machine can automatically turn or cannot stop

1. Control card failure; 2: Inverter failure

2. When opening the software of CNC engraving and milling machine, the computer prompts "Failed to open the card, please check the card"

1. Check whether the driver of the board is installed or replace the board with a PCI slot; 2. Reinstall the two data cables and check whether there is a broken needle in the current CNC engraving and milling machine software. Prompt: Axis alarm, initialization error number four

1. Check whether the two data cables of the computer and the CNC wood CNC engraving and milling machine are connected; 2. Check whether the fuse of the adapter board in the control box of the CNC wood engraving and milling machine is burnt out and replace the fuse; 3. Check the 85V power supply Whether the power supply is normal

Fourth, the CNC numerical control engraving and milling machine engraving dislocation or wrong size

1. Check whether the software path of CNC engraving and milling machine is correct; 2. Check the clearance of the screw rod and whether the fastening screws of the polished rod are loose; 3. Check that the software parameter settings are correct

V. The Z axis does not lift the knife when walking for a certain period of X axis, but presses to go up but goes down

1. Check whether the Z-axis motor of the CNC engraving and milling machine is running normally, the power and the current of the driver or its own fault; 2. Check whether the Z-axis motor line has a poor contact or is broken in the middle

6. The spindle motor of CNC CNC engraving and milling machine does not rotate or reverse

1. Check the parameter setting of the inverter; 2. Check whether the signal line of the inverter is connected reversely.

Seven, the CNC engraving and milling machine smashing phenomenon

1. The Z-axis motor power is not enough, and the coupling is loose; 2. The current of the Z-axis driver is too small, or the signal cable is connected incorrectly.

Eight, when the software is turned on, the axis closes

1. Problems with the driver or poor contact of the computer output signal wires; 2. Poor contact of the motor wires.

Nine, the limit phenomenon occurred in the engraving process of CNC numerical control engraving and milling machine

1. Check whether the engraving path exceeds the engraving range; 2. The soft limit of parameter setting in the software.

10.The CNC CNC engraving and milling machine is not powered on when the machine is turned on.

1. Check whether the start button wire is connected well and the button is burnt out; 2. Check whether the AC contactor is shorted or burned out.

11.The axis only moves in one direction when the button is moved

1. Check whether the optical fiber line is working normally and whether the line is in good contact; 2. Check whether the motor line is soldered.

Twelve, the sending software cannot be opened normally, and the things carved by the CNC engraving and milling machine appear abnormal.

1. Reinstall the new system and software; 2. Check whether the X and Y axis screws and screws are loose; 3. The carving knife has a problem.

Thirteen, the spindle motor suddenly stopped or slowed down during the work of CNC engraving and milling machine

1. The working voltage is unstable or overloaded, just add a voltage regulator; 2. Check whether the middle wire is connected well and whether the wire end is desoldered.

Fourteen, when the CNC numerical control engraving and milling machine sets the origin, sometimes the offset distance is forward and right.

1. The limit switch has failed, and the limit switch has been closed and popped open during the system's return to the system origin. Replace the limit switch; 2. The drive line is loose. Try to fix it tightly.

XV, Y-axis, Z-axis positions are not fixed when the CNC CNC engraving and milling machine is reset.

1. The limit switch is broken (the limit switch is always closed), then you can replace it; 2. The drive line is broken (the X axis is shorted with 14 and 15 pins, the Y axis is shorted with 13 and 15 pins, and the Z axis is 31 and 15 pins Short circuit), just change the drive line or separate the short circuit; 3, the drive board is broken, just change the drive board
