We must conduct a thorough inspection before use to ensure there are no issues with the machine and to identify any problems early on.
1. CNC Enclosure Inspection: Before operating the CNC lathe, open the CNC enclosure door and check all types of interface jacks, servo motor feedback line jacks, spindle pulse generator jacks, hand-crank pulse generator jacks, CRT jacks, etc. If any are loose, reinsert them securely, and ensure that any locking mechanisms are tightened.
2. Electrical Inspection: Prior to use, open the machine tool's electrical control box and inspect for loose relays, contactors, fuses, servo motor speeds, control unit outlets, and spindle motor speed control unit outlets. If any are loose, restore them to their normal state. Ensure that connectors with locking mechanisms are securely fastened. For machines with junction boxes, check the outlets on the junction box for loose wiring and make sure any locking mechanisms are tight.
3. Inspect the wiring of all buttons, switches, and indicator lights on the operation panel, and address any errors immediately. Check the outlets and wiring on the CRT unit. Ensure a good ground wire is in place; measure the ground wire of the CNC lathe, ensuring the ground resistance does not exceed 1Ω. Use a phase sequence meter to check the phase sequence of the input power, confirming that it matches the phase sequence marked on the machine.
4. Solenoid Valve Inspection: All solenoid valves should be manually actuated several times to prevent poor operation due to prolonged non-power supply. In case of any anomalies, proper records should be made for subsequent confirmation, repair, or replacement after power is restored.
5. CNC Machine Tool Limit Switch Inspection: Check the flexibility and stability of all limit switches' operation, and address any issues with poor movement or loose fixation immediately. Button and Switch Inspection: Inspect buttons and switches on the operation panel.
6. Equipment with secondary connections, such as power transformers, must confirm the consistency of the phase sequence of the secondary connections. Ensure that the phase sequence is correct on all parts of the CNC lathe. At this time, measure the power voltage and make a record.
