Laser engraving technology is widely used in the stone and granite industry. Linxuan provides custom solution for stone laser engraving. We manufacture industrial stone laser engraving machine with long-term after-sales service.

Traditional engraving methods (such as mechanical cutting, chemical etching, etc.) have some shortcomings, while laser engraving is an ideal choice for stone engraving.

Stone laser engraving machine is widely used in marble, granite, artificial marble plate, and other stone materials to engrave characters, images, or patterns because of its high engraving precision, fast speed, non-yellowing and non-fading characteristics, increasing the value of ornamental or collection, which is more convenient for inheritance.

Laser Engraving Stone Advantages

High Precision

Laser engraving machines can achieve micron-level fine engraving lettering and patterns, ensuring that markings are clearly visible.

Efficiency

The laser engraving speed is fast, the processing process is automated, and it is suitable for mass production.

Durability

Laser engraving forms permanent changes on the stone’s surface, with properties such as wear resistance, water resistance, and acid and alkali resistance.

Flexibility

Laser engraving can realize complex patterns, characters, and logos to meet individual needs.

Industries of Application

Stone Processing Industry

Used to make tombstones, souvenirs, architectural decorations, etc.

Jewelry Industry

For engraving diamonds, gemstones, jewelry, etc.

Artwork Industry

Used to carve sculptures, stone carvings artwork, etc.

Construction Industry

Used for marking stone floors, house numbers, etc.

When performing stone engraving, it is necessary to select appropriate power and parameters to avoid burning the stone surface or unclear engraving.

Power

Determine the appropriate laser power according to the hardness and color of the stone. Typically, harder stones require higher power.

Speed

Adjust the scanning speed of the laser engraver according to the complexity of the pattern to be marked and the required depth. Slower speeds generally result in deeper marks.

Focus distance

According to the height of the stone, set the appropriate focusing distance to ensure that the laser can completely penetrate the stone’s surface and form a clear mark.

How to Choose a Stone Laser Engraving Machine?

Choosing the right stone laser engraving machine is a critical step to ensure success.

Understand Application Requirements

Determine your specific application needs, including required engraving or marking materials, accuracy requirements, marking speed, and depth.

Laser Source

Choose the appropriate laser source, usually CO2 laser and fiber laser are common choices. CO2 laser is suitable for organic materials and some non-metallic materials, while fiber laser is suitable for metals and other materials.

Power

Choose the appropriate laser power based on your application needs. Generally, high-power lasers are suitable for deep and large-area markings, while low-power lasers are suitable for shallow engravings and fine markings.

Wavelength

Make sure the selected laser wavelength is suitable for the material you are marking. Lasers of different wavelengths have different effects on different materials.

Cooling System

Consider the cooling system of your laser marking machine to ensure the stable operation of the equipment and avoid overheating issues.

Auto Focus

Choose a machine with autofocus to simplify adjustments and achieve consistent focus.

Safety

Ensure that laser marking machines meet safety standards and that appropriate safety measures are in place to protect operators from laser radiation and other potential risks.

How to Operate the Laser Engraving Machine to Mark Stones?

Material Preparation

Prepare the stone for marking, making sure the surface is smooth, clean, and dry. Different stones may require different pre-treatment steps, such as cleaning or coating.

Positioning and Fixing

Position the stone correctly in the marked area, using a clamp or fixture system to hold it in the correct position.

Laser Parameters

Set the laser parameters including power, speed, frequency, and pulse width based on the selected laser source and material type.

Focus Adjustment

Use an autofocus or manual focus system to ensure the laser focus is on the surface of the stone.

Pattern Design and Control

Use appropriate software to design the pattern or text to be marked on the stone, ensuring correct placement and size.

Experiments and Tests

Before proceeding with batch marking, conduct some trials and tests to confirm the accuracy of the selected parameters and design.

Maintain

Regularly maintain the laser marking machine, including cleaning the optical path, replacing lenses, and keeping the equipment in optimal working condition.

Safe Operation

Follow the equipment manufacturer’s operating instructions and ensure operators are trained and take appropriate safety measures.

What Should We Pay Attention to When Laser Engraving Stones?

Material Selection

Different types of stones have different physical properties, hardness, and light transmittance.

Experiment and test in selecting laser parameters and material handling. Adjust laser power, wavelength, and marking speed for best results for different stone types.

Prevent Stones From Cracking

Laser engraving may introduce too much heat to the surface of the stone, causing it to break or crack.

Use low-power and high-frequency laser pulses to reduce heat build-up. Cooling systems such as gas injection cooling or water cooling can also be used to reduce temperatures.

Strategies to Improve Efficiency

In situations where complex patterns or deep engraving is required, laser engraving speed will be relatively slow.

Therefore, we need to optimize laser parameters, use higher-power laser sources, adopt multi-beam marking technology, or use advanced laser marking systems to improve production efficiency.

Safety and Environmental Considerations

Laser engraving stone may produce harmful gases or waste, and the use of lasers requires following safe operating guidelines.

Use effective emission and waste disposal systems to ensure workplace safety and train operators to comply with regulations for the use and maintenance of laser equipment.

Lens and Optical Path Maintenance

The lenses and optical path need to be kept clean and regularly maintained to ensure the stability and accuracy of the laser beam.

Establish a regular maintenance plan to regularly clean and inspect the optical path and lenses of the laser system to ensure that its performance is not affected.

Accuracy and Finesse

Some applications require very high precision and finesse, which may require higher levels of technology and equipment.

Choose an appropriate laser system, such as a femtosecond laser, to achieve greater accuracy and resolution.

Taking these issues and corresponding solutions into consideration can better cope with the needs of laser engraving stone and achieve better results, whether in the jewelry industry, stone industry, or other application areas.
