In fact, the cutting quality of CNC cutting machines is not stable, and the problems such as frequent replacement of wearing parts are more prominent, and it is found that users are not standardized enough in use and operation. At this time, it is necessary to turn off the switch in the power distribution cabinet; open the electric lock on the electric control panel, press the power button, cut off the power cord, connect the power cord to the power cord, and check whether the indicator light on the control box panel is normal; the numerical control circuit breaker Carry out internal self-diagnosis and check whether the error message is displayed; close the switch in the servo cabinet, press the servo switch key on the operation panel to supply power to the servo system, turn the pulse knob on the control cabinet panel to the ON position to backflush the filter , check whether the pulse is normal; test operation, confirm that each switch. The button is flexible. Reliably check whether the ash discharge flapper valve is normal; test run to confirm that the machine runs smoothly. Before cutting, spray powder and draw lines, pay attention to the explosive zinc powder, avoid flying, and wear a mask during use; when plasma cutting is performed on a CNC cutting machine, the limit and emergency buttons are reliable. When automatic ignition, pay attention to Personnel should not approach the high-voltage coil.
In addition, you also need to master some CNC cutting machine application skills:
1. Use a reasonable cutting distance. According to the requirements of the manual, adopt a reasonable cutting distance. The cutting distance is the distance between the nozzle and the surface of the workpiece. When perforating, try to use the distance twice the normal cutting distance or the height of the plasma arc transmission.
2. The perforation thickness of the CNC cutting machine should be within the allowable range of the machine system; the cutter shall not perforate the steel plate exceeding the operating thickness, usually 1/2 of the cutting thickness.
3. Keep the CNC cutting machine torch and consumables as clean as possible: Any dirt on the torch and consumables will seriously affect the work of the plasma system. When replacing consumables, put it on a clean flannel, check the connection pattern of the cutting torch frequently, and clean the electrode contact surface and nozzle with hydrogen peroxide.
4. When using the CNC cutting machine, cut the knife as little as possible. The backsplash of molten steel will damage the nozzle, which is one of the reasons for the damage to the cut. Drill on a pre-drilled drill.
