In the field of LCD/LED laser cutting, natural granite bases have become the preferred choice for many devices due to their excellent stability and vibration resistance. However, it is not a "master key" and there are certain limitations in practical use. Today, we will take you on a deep dive to uncover the "double-sided" characteristics of natural granite bases.
The advantages of natural granite bases are obvious to all. It has a high density and a compact structure, which can effectively suppress the mechanical vibration generated during laser cutting and reduce cutting errors. Meanwhile, it has a low coefficient of thermal expansion. Even if the ambient temperature changes, it is not prone to deformation, ensuring that the cutting accuracy remains consistently high. In addition, granite has stable chemical properties and remains undisturbed by common chemical reagents in production, thus having a long service life.
However, natural granite bases also have some limitations. One of the issues is the weight. Large granite bases can weigh several tons, which not only places extremely high demands on the load-bearing capacity of the factory floor slabs but also requires professional equipment for transportation and installation, increasing the difficulty and cost of construction. Secondly, natural granite has tiny pores. When used in combination with air flotation guide rails, it is prone to gas leakage, which affects the stability of the air flotation system and further interferes with the cutting accuracy. In addition, although granite has good thermal stability, in an environment with large temperature differences between day and night and high humidity, it may still undergo slight deformation due to moisture absorption and expansion. Long-term accumulation will affect the cutting accuracy.
But don't worry. These limitations are not insurmountable. For the weight issue, lightweight design can be adopted; And it is necessary to enhance the compatibility with the air flotation system; The installation of temperature and humidity sensors and the implementation of moisture-proof measures can reduce the impact of environmental factors.
Overall, although the natural granite base has its limitations, through scientific design and improvement, it can still exert powerful performance and provide reliable guarantees for LCD/LED laser cutting.
