What is a Leather Laser Cutting Machine?

Understanding Laser Technology

A laser cutter for leather works by using a high-power laser beam to cut shapes and patterns into the material. This involves the generation of a monochromatic light beam that is coherent in nature. The beam gets concentrated onto the surface of the leather, where it burns or vaporizes away material very precisely, thus enabling intricate designs and fine work to be done. There are two main categories of lasers used in such machinery:

• CO2 Lasers: These are mostly employed because they are efficient and work well with leather cutting. They operate at a wavelength of 10.6 micrometers and have power outputs that range between 30W to over 100W, which makes them suitable for thin as well as thick leathers.
• Fiber Lasers: Not commonly used for leather but can be applied where higher accuracy is required. Fiber lasers operate at a wavelength of 1.06 micrometers, often delivering higher energy densities, although marking and engraving are more their forte than cutting through thicker leathers.

The Different Types of Leather Used in Laser Cutting

The type of leather chosen significantly impacts the laser cutting and engraving quality. The main types of leather used in laser cutting are:

1. Full-Grain Leather:

• Description: The highest quality leather, maintaining the complete grain of the hide.
• Technical Parameters: Requires lower laser power settings to avoid burning, typically around 30-50W for cutting, and even lower for engraving.

2. Top-Grain Leather:

• Description: Slightly sanded and refinished to remove natural imperfections.
• Technical Parameters: Moderate power settings, ranging from 40-60W for cutting, ensuring clean cuts without excessive charring.

3. Genuine Leather:

• Description: More affordable, processed from the lower layers of the hide.
• Technical Parameters: Higher power settings, around 60-80W, because it is often denser and less uniform.

4. Bonded Leather:

• Description: Made from leather scraps bonded together with adhesive.
• Technical Parameters: Highest power settings needed, often exceeding 80W, due to the mix of leather fibers and adhesives.

Careful selection of laser power and speed is essential to achieving the best results for each type of leather, ensuring precision and quality without damaging the material.
