How to Use Fiber Laser Cutting Machine for Metal: A Comprehensive Guide

Introduction

Fiber laser cutting machines have revolutionized the metal fabrication industry with their precision, speed, and efficiency. If you are new to using fiber laser cutting machines, this comprehensive guide will walk you through the steps, from setup to the actual cutting process.

Setup and Calibration

Step 1: Power and Safety

Ensure that the machine is properly grounded and connected to a reliable power source. Familiarize yourself with the safety procedures and wear appropriate protective gear.

Step 2: Material Placement

Securely place the metal sheet or object that needs to be cut on the machine bed. Ensure that it is properly aligned and clamped in place to prevent any movement during cutting.

Step 3: Machine Calibration

Calibrate the laser cutting machine by checking the focus length and making any necessary adjustments. This step is crucial for obtaining precise cutting results.

Preparing for Cutting

Step 1: Design and Programming

Create or import the design you want to cut using a compatible software program. Make sure the dimensions and settings are correctly configured for your specific metal and desired outcome.

Step 2: Set Cutting Parameters

Based on the material type, thickness, and cutting requirements, set the appropriate laser power, cutting speed, and assist gas pressure. Consult the machine’s user manual or seek expert advice if needed.

Cutting Process

Step 1: Homing

Ensure that the laser head is in the home position, ready for the cutting process. This step helps to maintain accuracy and consistency during cutting.

Step 2: Start Cutting

Initiate the cutting process by selecting the appropriate program or file from the machine’s control panel. Supervise the process and monitor the cutting quality and progress.

Step 3: Finishing and Inspection

Once the cutting is complete, remove the cut metal pieces from the machine bed and inspect them for accuracy and quality. Make any necessary adjustments for subsequent cuts if required.
