Galvo System

The galvo system consists of two mirrors that can quickly and accurately direct the laser beam. These mirrors move in response to electrical currents, allowing the laser beam to be precisely and dynamically positioned on the leather surface. The galvo system determines the speed and accuracy of the engraving process.

Focus Lens

The focus lens helps to concentrate the laser beam onto a specific spot on the leather surface. It plays a crucial role in determining the engraving’s sharpness and depth. By adjusting the focus lens position, the engraver can achieve different effects, such as shallow surface markings or deep engravings.

Control Software

Control software is an integral part of any laser engraving machine. It allows users to create and edit designs, control the laser parameters, and manage the engraving process. The software provides a user-friendly interface and precise control over engraving settings, making it easier to achieve the desired results.

Preparing Leather for Laser Engraving

Proper preparation of the leather surface is essential to achieve high-quality engraving results. Here are the key steps involved in preparing leather for laser engraving:

Choosing the right type of leather

Not all types of leather are suitable for laser engraving. It is important to select a type of leather that responds well to the engraving process. Full-grain and top-grain leathers are commonly used for laser engraving due to their natural and smooth surfaces, which produce crisp and clear engravings. Split and suede leathers are more challenging to engrave and may yield less defined results.

Cleaning and prepping the leather

Before engraving, the leather should be thoroughly cleaned and prepared. Any dirt, oil, or debris on the surface can affect the quality of the engraving. Cleaning can be done using a soft brush or cloth and a mild detergent specifically designed for leather. The leather should be completely dry before proceeding with the engraving process.

Masking and alignment

Masking refers to the process of covering certain areas of the leather surface to protect them from the laser beam. This is particularly useful when engraving specific portions of a product or when multiple designs need to be engraved on the same item. Alignment is crucial to ensure that the engraving is centered and accurately positioned. Laser engraving machines often have alignment features, such as red dot pointers or camera systems, to aid in the alignment process.
