In the process of using 3D drill, there will be some faults, which can not work normally and affect the work efficiency. How can we effectively eliminate these faults? The following is to introduce the troubleshooting method of 3D drilling, so that our work can be carried out smoothly. Why can't 3D drill work? At this time, it is necessary to check whether the power supply is connected. After the power supply is confirmed, check whether the gear is in good gear. If everything is normal, please contact the manufacturer. < br style = "list style type: none;" / > 2. Why does the motor rotate and the spindle does not work? The main reason for this is to check whether the motor gear falls off. After the motor gear falls off, there is a gear connection between the motor gear and the headstock. < br style = "list style type: none;" / > 3. Why the 3D drilling is not round? The reason may be that the spindle extension rod of the drill chuck is not in the right position, or there is oil stain in the inner hole of the main shaft, or the quality of the drill chuck is poor. It is enough to replace the national standard drill chuck and extension rod. < br style = "list style type: none;" / > 4? When using the three-dimensional drilling and milling keyway, please read the instructions of the milling chuck in detail, and carry out it in turn according to the clamping sequence to ensure that the milling cutter is clamped correctly, so as to complete the three-dimensional drilling processing. < br style = "list style type: none;" / > the above is a brief introduction to troubleshooting methods of 3D drill. I hope the above contents can help you. If you have any questions, please contact us.
