1. In special cases, if the CNC cutting machine needs to be replaced with new equipment, it must be unloaded carefully. If welding is required in some places, remember to pay attention to safety, and do not use acid solder when welding.
2. Check the power supply device and type of the circuit board in time. If there is a high-voltage generator in the circuit board and the insulation is not good, it will be a big problem, so we must properly insulate it.
3. Be sure to cut off the main power before unloading to prevent electric shock, so you must remember when unloading.
4. It is necessary to find out the type and power configuration of the circuit board of the CNC cutting machine. According to the needs of the detection, it can be powered alone or all. Pay attention to high voltage, some plates are directly connected to high pressure, or there is a high voltage generator inside the plate, which requires proper insulation, and special attention should be paid when using it.
5. Sometimes, the screws of some parts of the CNC cutting machine or those similar small parts should not be confused. Some particularly thin parts should be placed in a more conspicuous position after removal to avoid accidental loss or loss. forget.
Some parts are not replaceable, even those types of parts are not original replacement. It would be time consuming and time consuming to forget that we were going to do a second split. For some parts that need to be interchanged, you can also mark each part when placing it, and the placement position should be clearly marked and marked.
6. The power supply should be disconnected to measure the resistance value between the lines. When measuring the resistance value, the red and black pen should be exchanged for measurement, and the larger resistance value will be used as the reference value. When measuring, you should also pay attention to whether the red and black pen plugs are installed correctly when using the red and black test pens.
Most circuit boards are brushed with solder mask, so the corresponding solder joints should be found as test points during measurement, and the solder film cannot be removed. Scrape off insulation at solder joints. This must be clearly confirmed during testing.
7. Since the parts in the CNC cutting machine are generally composed of many very thin parts, special care must be taken when disassembling to prevent damage. If it is disassembled, you can only call the manufacturer to express it.
Remember, before reassembling all the parts, be sure to check if there are any small parts that have not been installed, if there are installation errors, do not rework, it will not only waste our time but also reinstall and clean. It also affects the improvement of our work efficiency.
