Maintenance of CNC cutting machine

(1) Daily inspection and maintenance

1. Wire feeding mechanism. Including whether the wire feeding distance is normal, whether the wire feeding conduit is damaged, and whether there is an abnormal alarm. 2. Whether the gas flow is normal. 3. Whether the welding torch safety protection system is normal. (It is forbidden to close the welding torch for safety protection work) 4. Whether the water circulation system works normally. 5. Test TCP (it is recommended to compile a test program and run it after each shift)

(2) Weekly inspection and maintenance

1. Scrub each axis of the robot. 2. Check the accuracy of the TCP. 3. Check the residual oil level. 4. Check whether the zero position of each axis of the robot is accurate. 5. Clean the filter behind the water tank of the welding machine. 6. Clean the filter at the compressed air inlet. 7. Clean the impurities at the nozzle of the welding torch to avoid clogging the water circulation. 8. Clean up the wire feeding mechanism, including wire feeding wheel, wire pressing wheel and wire guide tube. 9. Check whether the hose bundle and guide wire hose are damaged or broken. (It is recommended to remove the entire hose bundle and clean it with compressed air) 10. Check whether the welding torch safety protection system is normal and whether the external emergency stop button is normal.

(3) Monthly inspection and maintenance

1. Lubricate each axis of the robot. Add white lubricating oil to the 1-6 axles. Oil No. 86E006. 2. Add butter to the red grease nipple on the RP positioner and RTS track. Oil number: 86K007 3. Add gray conductive grease to the blue oil filler on the RP positioner. Oil number: 86K004 4. Add lubricating oil to the needle roller bearing of the wire feeder. (A small amount of butter is sufficient) 5. Clean the gun cleaning device and add lubricating oil to the air motor. (Ordinary oil can be used) 6. Clean the control cabinet and welding machine with compressed air. 7. Check the cooling water level of the welding machine water tank, and replenish the cooling liquid in time (just add a little industrial alcohol to pure water). 8. In addition to completing the work of 1-8 items, perform all items of the weekly inspection.

(4) The maintenance work of the welding robot is the responsibility of the operator, and the personnel are assigned as follows:

Maintenance records must be added for each maintenance, equipment failures should be reported to the maintenance in time, and the equipment conditions and operations performed before the failure should be described in detail, and the maintenance personnel should actively cooperate with maintenance personnel to restore production smoothly! Conduct random inspections. It is recommended that the operator carefully check the integrity of the equipment at the handover of each shift, and record the operation of the equipment in each shift.
