Secondly, the cutting mode is improper: the cutting modes of the aluminum profile mainly comprise hacksaw cutting, manual cutting, mechanical cutting and the like. If the cutter is worn excessively or the cutting is not smooth enough, burrs are generated.

Third, poor material quality: the aluminum profile is mainly made of pure aluminum profile and alloy profile, and if the aluminum profile is processed by materials with poor quality, the hardness of the aluminum profile is insufficient, and burrs are easy to occur.

Fourth, ageing of the device: the aluminum profile processing equipment also ages with the increase of service life, and parts or mechanisms of some equipment are worn or damaged, which may cause deformation or instability of the equipment and further generate a burr phenomenon.
