BM114 LENS

About BM114 LENS

The BM114 is an auto-focus fiber laser cutting head used in CNC fiber laser cutting machines for precise metal cutting. It is designed for medium- to high-power fiber lasers (up to about 6 kW) and automatically adjusts the focus position to improve cutting efficiency and quality.

Basic Description

The BM114 laser head contains optical components such as a collimating lens, focusing lens, protective lenses, and nozzle assembly. It receives the laser beam from the fiber source, focuses it into a very small spot, and directs assist gas to cut metals like mild steel, stainless steel, aluminum, and brass.

Key Features

• Auto-focus system adjusts focus automatically to reduce manual adjustment.

• High power capacity supports fiber lasers up to 6 kW.

• Water-cooled optical lenses protects optics from heat during cutting.

• Air-cooled nozzle design extends nozzle and ceramic life.

• Large optical aperture (35 mm) reduces stray beam interference and improves cut quality.

• Compact structure reduces load on the machine Z-axis.
