The solution when a burr appears in laser cutting
- 2020-11-10 09:35:49 -

Burr refers to a variety of irregular metal parts such as sharp corners, hair edges, etc. that appear at the transition of the surface of the work piece in laser cutting and processing. Burr is one of the common phenomena in laser cutting machine processing, and it is also the two major problems that have not been solved so far in the study of metal cutting theory, "the generation and control of burrs". The burrs directly affect the dimensional accuracy, position accuracy and surface roughness of the machined work piece.

Q235 carbon steel 8mm laser cutting parts

Burrs only occur in metal cutting, and there is no burrs problem in non-metallic cutting. How are burrs produced? In fact, burrs are excessive residue particles on the surface of metal materials. If a material has burrs, then the material can be qualitative secondary, the more burrs, then the quality is naturally lower.

Laser cutting machine is a precision machine, operation is also a fine work, often a data error will cause its operation is not normal, so in the work to be strict and fine, reduce and avoid errors. Equipment and gas parameters, adjusted to the best, cut out of the work is no burrs, so that the laser cutting machine cutting more quality.

According to the working principle of laser cutting machine, the causes and solutions of burr are analyzed

1, cutting machine auxiliary gas purity is not enough. Solution: Explain how to increase the purity of the auxiliary gas.

2, the cutting machine's laser beam add point has been offset. Solution: focus on debugging, timely adjustment.

3, laser cutting machine operation time is too long and produce instability. Solution: Turn off the machine to restart and let the machine rest.

4, the focus of the beam of the upper and lower position deviation. Solution: Adjust the position of the focus to the offset position it produces.

5, the output power of the machine is not enough. Solution: Check that the laser cutter is working properly. Abnormally, repair and maintenance are required in a timely manner. If normal, check that the output values are correct.

6, cutting machine line cutting speed is too slow. Solution: Adjust and improve the line cutting speed in a timely manner.

Metal laser cutting machine is a precision machine, operation is also a fine work, often a data error will cause its operation is not normal, so in the work to be strict and fine, reduce and avoid errors.
