Description

Technical Field

[0001] This utility model belongs to the field of laser cutting technology and relates to a high-precision laser cutting head. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed gas flow coaxial with the laser beam removes the molten material, thus cutting the workpiece. Laser cutting is a type of thermal cutting method.

[0003] Currently, laser cutting heads are only fixed to the mounting part of the laser cutting machine during use, without any limit or fixation measures for the laser cutting head. When the laser cutting head moves continuously during operation, the bolts are prone to loosening, which affects the stability of the laser cutting head operation and the processing accuracy.
