The diversity of fitness equipment also puts forward high requirements for processing. Various specifications and shapes make traditional processing complicated and inefficient. Laser cutting has high flexibility. It can customize flexible processing for different pipes and plates. After processing, the finished product is smooth and burr-free, without secondary processing. The quality and efficiency are greatly improved compared with traditional processes. Small pipe cutting by fiber laser and plasma,need fast cutting speed, Diameter of pipe usually range from 5-200mm, length 3-12meters, Thickness of pipe is 0.2-5mm
