Metal cutting laser technology has transformed the manufacturing industry. It offers a precise and efficient way to cut various metals, making it a popular choice for many applications.

In this blog post, we will explore the world of metal cutting lasers, including how they work, their advantages, applications, and cost considerations.

What is Metal Cutting Laser?

Metal cutting laser technology uses a high – power laser beam to cut through metal. The laser beam is focused on the metal, heating it to its melting point. The molten metal is then blown away by a stream of gas, such as oxygen or nitrogen, leaving a clean cut. This process is highly precise and can be used to cut a wide range of metals, including stainless steel, aluminum, and titanium.

How Does Laser Cutting Work?

Laser cutting works by focusing a high – power laser beam onto the metal surface. The laser beam heats the metal to its melting point, and the molten metal is blown away by a stream of gas. This process creates a clean cut with minimal burrs or rough edges. The precision of laser cutting allows for intricate cuts and detailed designs, making it a popular choice for many industries.

Types of Lasers Used

There are several types of lasers used in metal cutting, including CO₂ lasers, fiber lasers, and neodymium lasers. CO₂ lasers are commonly used for cutting metals and offer high – quality cuts. Fiber lasers are more efficient and have a longer lifespan than CO₂ lasers. Neodymium lasers are used for cutting thicker metals and offer high – precision cuts.

Advantages of Laser Cutting Machine For Metal​
