QBH BM111 Series 3.3KW Auto-Focusing Fiber Laser Cutting Head for Laser Cutting Machine Laser parts

This laser head is mainly for laser power from 1000W to 3000W. (We recommend 1000W, 1500W,2000w, 3000W), supporting different laser powers on the market, like IPG, SPI, Raycus...etc.

It has proved stable on many laser cutting machine brands, like Hans laser, Farely, Qiaolian....etc.

Autofocus head greatly improves the pierce efficiency on thick plates. If your cutting work has many thick carbon steel plates, Autofocus cutting head will save at least 50% pierce time.

But before you buy this head, please make sure your CNC controller supports the autofocus function of the laser head.

Key feature:

1. Optimized optical configuration, smooth and efficient airflow design,

2. Knob type focus adjustment, high precision, flexibility. adjustment range: 20mm, accuracy: 0.05mm.

3. Drawer-type design of protection glass seat, simple and fast to replace protection glass.

4. Built-in ring-blowing and side-blowing structure inside the protective glass seat, offers protection from cutting reflective material and dross flying during piercing on the thick plate.

5. The collimator and focus lens parts both have a water-cooling structure, which enables the laser head to support laser power up to 4kw.

6. The collimator and focus lens both use special composite lenses, ensuring high-quality optical beam and cutting.

7. QBH and QD fiber connectors are all available and support almost all laser power brands on the market.

8. Modular design, easy maintenance
