What is The Right Laser Cutting Machine for Leather?

Several types of laser-cutting machines allow you to cut different materials. However, you need to be cautious when dealing with the delicate nature of leather.

The size of your project, your budget, and the required precision level significantly impact the choice of laser cutting machine. The desired power of a fabric laser-cutting machine also influences this decision. Of various laser cutting machines, the wavelength and power of the CO2 laser cutting machine make it the most suitable option for laser cutting.

CO2 laser employs a mixture of carbon dioxide and some auxiliary gases in a gas tube to generate the laser beam. Auxillary gases include helium, hydrogen, and nitrogen. Light is emitted when electricity is passed through the gas tube. The light is transformed into a high-intensity laser beam as it passes through mirrors. According to SignMasterSystems, the laser emitted from the leather laser-cutting machine has enough heat to cut hard materials, including leather.

The wavelength of CO2 is around 10.6 micrometers. Organic materials readily absorb this wavelength. It enables you to manufacture multiple products from natural materials.
