The Method Of Solving The Burr At The Bottom Of Laser Cutting

Burr is one of the common phenomena produced in the laser cutting machine processing, but also in the theoretical study of metal cutting has not yet been resolved in the two major problems "burr generation and control", burr directly affects the dimensional accuracy of the processed workpiece, the shape of the precision and surface roughness. Today I will talk about the laser cutting process burr common causes and solutions.

Reason 1: laser cutting machine produces laser beam focus of the upper and lower position deviation, resulting in energy is not just convergence to the workpiece, the workpiece is not fully vaporized, so that the amount of slag produced increased, not easy to blow off, which is more likely to produce burrs.

Solution: adjust the position of the laser beam focus, according to the offset position it produces, adjusted to the best state.

Reason 2: The output power of the laser cutting machine is not enough to effectively vaporize the metal, thus producing excessive slag and burrs.

Solution: check the normal operation of the laser cutting machine, if not normal, you need to repair and maintain in a timely manner; if normal, but also to check whether the output value is correct.

Reason 3: The cutting line speed of the laser cutting machine is too slow, which destroys the surface quality of the cutting surface and produces burrs.

Solution: Adjust and improve the cutting line speed in time to make it reach the normal value.

Reason 4: The purity of the auxiliary gas of the laser cutting machine is not up to the required standard, which will also make the workpiece produce burrs.

Solution: Replace the auxiliary gas with higher purity.

Reason 5: the laser cutting machine working time is too long, so that the equipment has an unstable working condition, which will also lead to the generation of burrs.

Solution: Turn off the laser cutting machine, after a period of time and then restart and move, so that it gets enough rest.
