What Are The Causes Of Burrs In Laser-cut Workpieces?

Feb 26, 2019

The burr refers to irregular metal parts such as sharp corners and burrs that appear at the transition of the surface of the workpiece during laser cutting. The burr is one of the common phenomena in the processing of laser cutting machines, and it is also the two major problems that have not been solved so far in the research of metal cutting theory, "the generation and control of burrs". The burr directly affects the dimensional accuracy, shape accuracy and surface roughness of the workpiece being machined.

First, the laser cutting machine processing sheet metal burr causes:

The main reason for the occurrence of burrs in the processing of sheet metal by laser cutting machine: When the laser cutting machine is processing the workpiece, the high energy generated by the laser beam illuminating the surface of the workpiece causes the surface of the workpiece to vaporize rapidly and evaporate to achieve the purpose of cutting. Titanium Machinery is the main product of the company with rotary top, screw, shaft machining, CNC lathe machining, shank and collects post. However, there is a core device that we must pay attention to, that is, auxiliary gas. The auxiliary gas is the slag that blows off the surface of the workpiece after the surface of the workpiece is vaporized. If the auxiliary gas is not used, the slag is cooled and a burr is formed on the cutting surface. This is the main reason for the formation of burrs.

Another reason is the quality of the equipment itself, as well as the parameter setting factors. When the customer purchases the laser cutting machine, the professional operator must debug the equipment.
