The Basics of CNC Laser Cutting

CNC laser cutting is often the first step in 2D sheet metal fabrication. It offers a faster turnaround compared to punching, making it especially efficient for short production runs. In addition, laser cutting provides a higher level of precision and consistency than conventional mechanical cutting methods.

The process produces clean, accurate edges that meet strict tolerances. It is a flexible and versatile manufacturing solution, particularly suited for fabricating intricate shapes that require smooth, distortion-free finishes.

How Laser Cutting Works

Laser cutting machines focus a high-powered laser beam onto the surface of the material, converting light energy into intense heat. This concentrated heat melts or vaporizes the material, creating a fine cutting line. The laser head moves according to the programmed path, enabling the machine to cut complex shapes with precision.

There are three main types of CNC laser cutting machines:

CO₂ Laser Cutters

Best suited for non-metallic materials such as plastics, wood, acrylic, textiles, and certain thin metals.

YAG (Yttrium-Aluminum-Garnet) Laser Cutters

Ideal for applications requiring high energy density, such as marking, engraving, and specialized cutting of metals and ceramics.

Fiber Laser Cutters

The most versatile and widely used technology for sheet metal cutting. Fiber lasers provide faster speeds, lower maintenance, and higher energy efficiency when cutting steel, aluminum, stainless steel, copper, and brass.

Benefits of CNC Laser Cutting

Preparing a High-Quality Master Model

Delivers burr-free, distortion-free cuts.

Carrying Out the Curing Process

Perfect for short runs as well as mass production.

Material Flexibility

Cuts metals, plastics, composites, wood, and more.

Reduced Waste

Narrow kerf width means optimal use of raw material.
