The CNC angle drill is an iron tower production line used for drilling, marking and cutting off angle steel. After the control circuit of the CNC angle drilling machine is installed, the following items shall be checked before power connection.
10 items’ inspection of control circuit of CNC angle steel drilling production line:
1. Whether the codes and marks of each component are consistent with those on the schematic diagram;
2. Whether various safety protection measures are reliable;
3. Whether the control circuit of the CNC angle steel drilling machine meets the various functions required by the schematic diagram;
4. Whether all electrical components are installed correctly and firmly, and whether the resistance value of each component is normal;
5. Whether the square number of each conductor meets the requirements, and whether each terminal is firmly connected;
6. Whether the wiring meets the requirements and is neat, and check the insulation resistance between items;
7. Whether the color of each button, signal lamp and various circuit insulated wires meets the requirements;
8. Whether the motor installation meets the requirements;
9. Whether the protective circuit wires are connected correctly, firmly and reliably;
10. Check whether the insulation resistance of the electrical circuit of the angle drill meets the requirements.
