激光切割机在加工钣金时会出现烧边以及挂渣的情况,不仅影响产品的精度以及美观,还降低了产品品质,给企业带来很大经济损失。金属激光切割机加工烧边的是主要原因是什么了?
The laser cutting machine will have the condition of burning edge and hanging slag when processing the sheet metal. It not only affects the precision and beauty of the product, but also reduces the quality of the product, and brings great economic loss to the enterprise. What is the main reason for metal laser cutting machine burning edge?
金属激光切割机在加工钣金时会产生大量的热量,正常情况下,切割产生的热量会沿着切缝扩散到被加工钣金中得到充分的冷却。金属激光切割机在小孔的加工中,孔外侧可得到充分的冷却,单孔内侧的小孔部分却因为热量可扩散的空间小,热能过于集中从而引起过烧,挂渣等。另外,在厚板切割中,穿孔时所产生的堆积在材料表面的熔融金属以及热量积累会使辅助气流紊乱、热量输入过多,从而引发过烧。
The metal laser cutting machine produces a large amount of heat when processing the sheet metal. Under normal circumstances, the heat generated by the cutting will be cooled down to the processed sheet metal. In the processing of small holes, the metal laser cutting machine can be fully cooled on the outside of the hole. The small hole inside the single hole is small because of the heat diffusible space, and the heat is too concentrated to cause excessive burning, slag and so on. In addition, in the thick plate cutting, the molten metal accumulated on the surface of the material and the accumulation of heat can make the auxiliary air flow disorder and the heat input too much, thus causing excessive burning.
