Burr may occur in this case because the lens is dirty. At the beginning, the lens is clean, so there is no problem in cutting. At the back, the lens is dirty, so burr appears.But the most fundamental reason is the use of air as auxiliary gas, air is not clean, there is oil and water caused.In this case, it is necessary to add water and oil removal equipment at the back end of the air compressor to ensure the normal operation of the cutting operation.To remove water is to add a cold dryer, to remove oil is to add a back end oil removal equipment.The compressed air after such treatment ensures the normal operation of the cutting operation, protects the laser cutting equipment, and extends the service cycle of the lens and the maintenance cycle of the laser cutting equipment.At the same time, the problem of oil and water pollution is avoided, which will cause more damage to laser equipment.
Laser cutting machine in the cutting as long as the right way to operate is generally not a problem, cutting effect is also very good.But if you use the laser cutting machine when cutting some burrs need to be paid attention to, timely find out the specific reasons and solve is the best.
Laser cutting machine has been common in sheet metal processing, due to its high efficiency and high quality of finished product cutting, has become the standard of sheet metal processing station.But some customers in the use of laser cutting machine, cutting out the workpiece burr, many people think it is the quality of laser cutting machine products, in fact, not so.
In the process of sheet metal processing, the gas purity of laser cutting machine, parameter Settings, will affect the processing quality, equipment + gas + parameters, adjust to good, cut out of the workpiece is no burr.
How do burrs happen?
Burrs are simply excess residue particles on the surface of a metallic material.When the laser cutting machine is processing the workpiece, the energy generated by the laser beam shining on the surface of the workpiece vaporizes and evaporates to achieve the purpose of cutting.But here's a device that we're going to pay attention to, which is the gas.
The gas is to blow off the slag on the surface of the workpiece after gasification of the irradiated surface of the workpiece. If the gas is not used, the slag will form burrs attached to the cutting surface after cooling.Therefore, gas purity should be high, you can change to a higher quality gas supplier, gas purity is critical, do not use cylinder gas, because after two filling, the purity is not good, also waste gas.
Another reason is the quality of the equipment itself, as well as the parameter setting factors, so when customers buy laser cutting machines, they have to ask experienced operators to adjust the equipment.So we should try our best to adjust the cutting parameters to the best, air pressure flow focal length cutting speed, after many adjustments, depending on the parameters provided by the machine is not cut high quality workpiece
