Operating Rules of CNC Machining Center

A. Machine Tool Maintenance


1. Clean up and maintain the machine tool half an hour before work every day. If air gun or oil gun is used to clean chips, the spindle must have a knife.


It is forbidden to blow spindle cone holes with air gun or oil gun, so as to avoid small particles such as chips being blown into the spindle holes, which will affect the cleanliness of the spindle.


2. Check whether the lubricating machine is working properly and whether the lubricating oil is sufficient. Start the machine in the normal order.


3. Start the spindle (the speed is 501R/M) to preheat the spindle before the machine is working properly.






B. Machine Tool Operation


1. Confirm the type, dimension and allowance of the blank before going on the machine and sanding the blank.


2. Confirm the placement of the workpiece and the processing sequence after the machine is installed, and complete the table action.


3. The speed of the computer gong processing depends on the cutting tool if the “dividing the middle bar” is needed. In order to ensure the accuracy of the dividing, the “G0 G54 X0 Y0” can be used for inspection after the dividing.


4. Check again before formal processing to confirm the position of the workpiece and whether the number is correct.






C. Processing Notes


1. Before each procedure is processed, it is necessary to strictly confirm whether the tool is in accordance with the procedure.


2. The length of the cutter and the suitable clamping tool head should be confirmed when loading the cutter.


3. Keep the same area for each tool alignment in the same workpiece to ensure the accuracy of tool alignment.


4. Blow with air as far as possible in the roughening procedure and inject oil in the light knife procedure.


5. Clean up the aluminium residue in the machine tool before spraying oil with a light knife to prevent the aluminium residue from absorbing oil.


6. Dongguan Machinery Parts Processing Operators shall not leave the machine tool or regularly check the operation status of the machine tool while the machine tool is running on its own. If they need to leave halfway, they must designate relevant personnel to check.


7. If excessive machining allowance is found in the process of processing, the X, Y and Z values must be cleared by “single segment” or “pause” and then manually milling them off and then shaking them back to “zero” to allow them to run on their own.


8. In the process of Dongguan high-speed computer gong processing, if a knife collision is found, the operator must stop immediately, such as pressing the “emergency stop” button or the “reset” button or setting the “feed rate” to zero, etc.


9. Do not turn on the door to avoid flying knife or workpiece while the machine is running.


10. Workpiece must be deburred in time after it is off the machine.


11. At the end of work, CNC processing operators must make timely and accurate handover to ensure that follow-up processing can proceed normally.


12. Make sure the tool library is in the original position before shutdown, and the XYZ axis is in the middle position. Turn off the power supply and the total power supply on the machine tool operation panel in turn.


13. In case of heavy thunderstorm, the power supply must be cut off immediately.
