Conoscere la forza della macchina per il taglio laser nel taglio dell'acciaio

3 luglio 2025

1 Basic Principle

A macchina per il taglio laser focuses a high-energy-density laser beam onto the surface of the steel, instantly melting or vaporizing the metal. At the same time, high-pressure assist gas (such as oxygen or nitrogen) blows away the molten material, achieving precise cutting.

2 How Thick Can It Cut?

Mild Steel (Carbon Steel):

Standard power (1–3 kW) fiber laser cutting machines can typically cut 1–20 mm thick mild steel.

High-power lasers (6–20 kW) can cut up to 40–50 mm or more, but cutting thicker plates requires higher power, advanced cutting heads, optimized gas flow, and precise cutting techniques.

Acciaio inossidabile:

1–3 kW machines can normally cut 1–12 mm thick stainless steel.

High-power machines can cut over 30 mm, but the cutting speed is lower.

Alloy Steel, Galvanized Steel, etc.:

Cutting thickness is similar to mild steel, but some alloy steels require precise parameter control to avoid edge hardening or discoloration.

3 Key Factors Affecting Cutting Capacity

Potenza laser: Higher power means stronger cutting capability.

Cutting Head & Nozzle: High-quality optical components and nozzles improve cutting results.

Assist Gas: Mild steel is typically cut with oxygen (which promotes combustion and boosts cutting power); stainless steel is usually cut with nitrogen to keep the edge oxidation-free.

Material Condition: Flat, clean surfaces produce better cuts. Rust or surface defects can affect cut quality.

4 Cutting Quality

Laser cutting produces narrow kerfs (typically 0.1–0.5 mm), smooth and clean edges with good perpendicularity, and a small heat-affected zone (HAZ). This reduces the need for secondary processing.

5 Typical Applications

Steel structures and sheet metal parts

Mechanical components

Construction elements

Produzione automobilistica

Kitchenware and decorative parts

Sintesi:
