Key Components of a DIY Fiber Laser Cutting Head

A fiber laser cutting head consists of several critical parts that work together to deliver precise cuts. Here’s what you’ll need

1. Fiber Laser Source – The heart of the system, generating the laser beam. Roclaser offers high-quality fiber laser modules with adjustable power for different material thicknesses.

2. Collimating Lens – Expands and straightens the laser beam for better focus.

3. Focusing Lens – Concentrates the laser beam onto the material for clean cuts.

4. Nozzle – Directs assist gas (such as nitrogen or oxygen) to enhance cutting efficiency and reduce slag.

5. Cutting Head Body – Houses the optical components and ensures stability.

6. Motion Control System – A CNC controller (like Roclaser’s user-friendly CNC systems) guides the laser head for accurate movement.

Step-by-Step Assembly Guide

Building your own DIY fiber laser cutting head requires careful assembly. Follow these steps

Step 1 Secure the Laser Source

Mount the fiber laser module securely to a stable frame. Ensure proper cooling (air or water) to prevent overheating.

Step 2 Install the Collimating Lens

Align the collimating lens to expand the laser beam uniformly. Misalignment can cause power loss or uneven cuts.

Step 3 Add the Focusing Lens

Position the focusing lens to concentrate the laser beam to a fine point. The focal length determines cutting depth—Roclaser’s adjustable lenses provide flexibility.

Step 4 Attach the Nozzle

Choose a nozzle size based on material thickness. A 0.8mm to 2.0mm nozzle works well for thin to medium metals.

Step 5 Connect the CNC System

Integrate the cutting head with a CNC motion controller for automated precision. Roclaser’s plug-and-play CNC kits simplify this process.

Step 6 Test and Calibrate

Perform test cuts on scrap metal, adjusting power, speed, and focus until achieving clean edges.
