We supply the laser cutting heads with auto-focusing function and you can easily cut uneven surface metals.

Laser cutting head is one of most important parts of laser cutting machines. The traditional cutting head only includes focusing lens and nozzle and does not have auto-focus function.If there is no auto-focus, the spacing between the focus lens and workpiece will not be same, which results in different focused beam diameters and then different power densities at different positions. Thus the cutting quality may be different at the positions.

Based on the requirements from the market, we have developed self-floating laser cutting heads. By using capacitive sensor and auto motor moving system, the spacing between the focus lens and workpiece will be kept same at any position of the cutting field. The response time is millisecond range only and the system is stable and reliable.
