In metal forming processing, in addition to deep drawing and stamping, which are important processes, the laser cutting involved is also important. Laser cutting due to its high precision, high speed and wide applicability, so that the metal processing industry can achieve rapid and accurate cutting of complex patterns, significantly improve production efficiency, reduce processing costs, while providing great flexibility for customization and small batch production, has become an indispensable key technology in modern manufacturing.
First copy the program into the program, and then the corresponding material and thickness of the cutting parameters out, change the corresponding nozzle, hit the center, adjust the focus, make sure that the program is correct gas have been turned on can be cut. For playing the center, you need to practice more, to master the feel in order to play the right light faster.
Nozzle: cutting carbon steel below 6MM with a 1.0 nozzle can be cut, cutting 8MM, 12MM carbon steel with a 1.5 nozzle, 14MM above carbon steel with a 2.0 nozzle. Generally we use 2.0 nozzles for stainless steel below 4MM, and 2.5 nozzles for stainless steel above 5MM. Cutting carbon steel we use double nozzles, cutting stainless steel with a single nozzle.
Cutting gas: oxygen pressure through the CNC control pressure, but the pressure reducing valve this side of the control pressure shall not exceed 0.5MPA (otherwise the electronic valve will not open), nitrogen gas pressure maximum of 25 kilograms.
Below 3MM stainless steel perforated with nitrogen, cutting stainless steel above 4MM or cutting carbon steel perforated with oxygen. Cutting more than 3MM stainless steel, after punching the hole, it is best to dig a small hole after cutting, digging radius defined in the parameters. Cutting stainless steel below 2MM nitrogen pressure 8 kg can be, cutting 3MM, 4MM stainless steel nitrogen pressure 10 kg is enough, 5MM, 6MM stainless steel nitrogen pressure 12 kg, cutting 8MM stainless steel nitrogen pressure needs 15 kg. If you use oxygen to cut stainless steel, you only need to cut it as carbon steel.
Cutting: before cutting the focus position is well adjusted (expert database notepad inside all recorded a reference), you can first find a piece of stainless steel, and then cut it.
(there is a reference value recorded in the notepad of the expert database), you can find a piece of the same thickness of the material to test cut first, and then cut the product after adjusting to the optimal state. For the cutting process of tool compensation, if you use the knife to compensate, always use the left knife to compensate, follow the principle of internal reverse and external smooth, try to cut a small square before cutting, in the parameter inside the Kerf adjusted, and then cut; if you don't use the knife to compensate for the need to change every “G41” to “G41” in the program; G41”. For the cutting of non-metallic materials to use mechanical sensors.
Laser gas exchange: laser every 72 hours will need to change the gas, when you see the laser on the GASCHANGE IN MAX24 alarm shows that the laser needs to change the gas, this time just need to drop the high-pressure, open the gas cylinder in the laser on the electrical cabinet press F7 → F6 → F2 → F7 can be realized gas exchange (implementation of the note that this process must ensure that the LASERON open). Wait a few minutes to wait for the gas exchange to be completed after turning off the gas cylinder can be. Note that after the appearance of GASCHANGE INMAX24h this alarm laser can still be used normally for 24 hours, but try to see this alarm on the replacement of the gas, so that the quality of the beam is more secure.
