1. Adjust the steel plate that the NC cutting machine is cut, keep parallel with the track as far as possible.
2. According to different plate thickness and material, reset cutting speed and preheating time in the machine, set preheating oxygen, cutting oxygen reasonable pressure.
3. After ignition, no one shall touch the flame area. The operator should take the cutting method with small splash as far as possible to protect the cutting nozzle.
4. Check CNC cutting machine heating flame, as well as cutting oxygen jet, if found cutting nozzle dirty or damaged, should be timely replacement, cleaning. Cleans the mouth to use the tool to clean.
5. Tempering occurs during the cutting process, timely attention should be paid to equipment operation, such as hair The existing abnormal situation, such as smell of gas and other odors, should press the tight stop switch, timely launch of the work position, strictly prohibited to boot off the scene.
6. Operators should note that after cutting a workpiece, the cutting torch should be lifted back to the original position, running to the next station, in the cutting.
7. CNC cutting machine operators should choose cutting speed according to the provisions of the given cutting elements, and do not allow to increase the equipment load simply to improve the work, and deal with the relationship between equipment life and rate and environmental protection.
8. Bridge is not allowed to pass over the equipment when the suspension is in operation.
9. Take cutting machine to process large thickness plate, cutting is easy to produce after dragging, cutting will end due to the reason of after dragging, the bottom of the workpiece has the phenomenon of cutting, so that the workpiece can not be separated. For solving this problem, the cutting torch can be tilted back about 10° when the cutting is about to end and the cutting torch is about to be removed from the workpiece, and the cutting speed can be slowed down, which can reduce the rear drag. In order to make the gas cutting process go smoothly, the cutting torch is inclined at the beginning of the cutting, and after the flame penetrates the workpiece, the cutting torch is gradually restored to the vertical position while moving.
10. The whole oxygen supply system of NC cutting machine, including pressure reducer, various joints and valve parts, cutting torch intake pipe, cutting nozzle aperture and so on, should meet the corresponding oxygen supply capacity and avoid throttling phenomenon. According to the thickness of the steel plate and cutting length, prepare enough gas source, so as not to interrupt the cutting halfway due to the exhaustion of oxygen.https://www.wxsilvercoast.com/
