Why the laser cutting machine cutting burr

Laser cutting machine is a kind of common cutting equipment, laser cutting machine is very widely used in metal processing industry, the leading cause of burr formation processing parts occurred: laser cutting machine laser focus position is not correct, do focus bearing test requirements, on the basis of the focus offset adjustment; Laser output power, needs to check the laser generator operation is normal, if it is normal, then investigate laser control button on the output value is correct, try to adjust; Cut the linear speed too slow, needs to increase the linear velocity when operating control; Not cut gas purity, cut demand supply high quality homework gas; Laser focus shifts, bearing test needs focus, on the basis of the focus offset adjustment; Time is too long to present machine's operation instability, needs to turn it off from the start at the moment.
