Characteristics and Processing Challenges of Stone

Stone is a hard, natural material with diverse textures, including granite, marble, jade, shale, and sandstone. Different types of stone vary significantly in hardness, density, and grain structure, directly affecting processing methods and engraving results. For example:

Granite has high hardness and excellent wear resistance but tends to crack during mechanical processing.

Marble has a relatively fine texture but is brittle and sensitive to thermal stress.

Traditional engraving methods, such as manual carving or mechanical cutting, face the following limitations:

Low efficiency: Manual carving is time-consuming, while mechanical tool processing requires multiple passes, making it difficult to meet mass production demands.

Limited precision: Complex patterns or fine text are hard to achieve accurately, often leading to errors.

Material damage: Direct tool contact with stone surfaces can cause cracks, chipping, or surface damage, especially with hard stones.

Design restrictions: Complex artistic textures or gradient effects are difficult to realize with traditional methods.

Laser processing brings significant breakthroughs in stone applications:

Non-contact processing: The laser beam does not physically touch the material, avoiding tool-induced damage.

High precision and controllability: Laser power, pulse width, and scanning speed can be precisely adjusted to achieve micron-level detail on hard stone.

Adaptability to various textures and hardness: Whether granite or jade with complex textures, lasers can ensure stable and uniform marking/engraving results.

Complex design realization: With programmed laser paths, it is easy to produce text, logos, patterns, and even gradient effects, meeting both artistic and commercial needs.

Thus, laser technology not only solves efficiency and precision issues in stone processing but also expands creative possibilities, making carved products both beautiful and durable.
