Fiber laser cutting machine how to accurately adjust the focus?

Fiber laser cutting machine in the metal industry in the application to generalization, as the fiber laser manufacturers Xin laser give us some tips: high precision, high accuracy as metal laser cutting machine earnestly to survive, if the metal laser cutting machine cutting precision of less than the current domestic metal laser cutting machine problems are basically reflected in the focus of the problem, to improve the precision for cutting laser cutting machine, and accurate adjustment of focus metal laser cutting machine, there is What is a good way?

Firstly, metal laser cutting machine to adjust the focus of the swash plate method, that is, with a vertical axis and a plastic plate at an angle of pulling it horizontally, looking for the smallest of the metal laser cutting machine laser beam focus.

Followed by metal laser cutting machine to adjust the focus of the printing method, it is to give metal laser cutting machine cutting head from the top down movement, plastic sheet laser beam printer, print the smallest diameter at the focus.

Secondly, compare a little trouble metal laser cutting machine is adjusting the focus collimator law, despite the trouble but also a common method in which the output of metal laser cutting machine plus a collimator is expanded beam treatment, after the beam expander larger beam diameter, divergence angle becomes smaller, so that within the scope of the proximal and distal cutting work before the focus beam size close to unity. Increase the cutting head of an independent movement of the lens of the lower shaft, metal laser cutting machine nozzle to control it with the Z-axis surface distance of two independent parts. When moving the machine table or the optical axis, the beam axis from the proximal to distal F also move the beam diameter of the focused spot is consistent over the entire working area.

The final step is to adjust the focus of metal laser cutting machine blue spark method to remove metal laser cutting machine cutting head nozzles, air blowing, the laser hit the stainless steel plate, so that the cutting head from the top down movement, until the blue spark at the maximum focus, so you can calculate the focus, after the cutting process take a different focus depending on the thickness of the sheet.

For flying optics cutting machine, since the beam divergence angle, cut the proximal and distal length of time the process is different, there are some differences focused beam size before. The diameter of the incident beam, the smaller the diameter of the focal spot.

Align the focus of metal laser cutting machine, it means improving the efficiency of metal laser cutting machine, further, that is to improve the production efficiency of the entire enterprise.
