In the field of LCD/LED manufacturing, laser cutting is a key process for shaping precision components, and granite, with its unique natural damping properties, brings significant advantages to this process.
Outstanding vibration control ensures cutting accuracy
During the laser cutting process, the operation of the equipment generates vibrations. Even the slightest vibration can cause problems such as positional deviation and rough cutting edges, seriously affecting product quality. Granite has excellent damping performance. Its dense mineral structure inside and the interaction between particles enable it to quickly absorb and attenuate vibration energy like an efficient shock absorber. Studies show that the internal damping coefficient of granite is 15 times greater than that of steel, which means that during laser cutting, it can keep the vibration at an extremely low level. For instance, when cutting the fine circuits of LCD screens, the granite base can quickly suppress the vibration of the equipment, enabling the laser beam to be precisely positioned and controlling the cutting accuracy at the micrometer level. This effectively avoids defects such as short circuits or open circuits caused by vibration, significantly improving the product yield rate.
Stabilize the cutting process and extend the service life of the equipment
Frequent vibration not only affects the cutting accuracy, but also accelerates the wear of equipment components, reduces the service life of the equipment and increases maintenance costs. The high damping property of granite can reduce the vibration amplitude and frequency during equipment operation, and lower the impact and friction between components. Take LED chip cutting as an example. For laser cutting equipment that has been frequently used for a long time, the wear degree of its key components such as guide rails and motors is significantly reduced under the vibration damping effect of the granite base, the maintenance cycle is extended, and the overall service life of the equipment is significantly increased, saving a large amount of equipment update and maintenance costs for enterprises.
Optimize thermal stability to ensure stable cutting quality
A large amount of heat is generated during laser cutting. If the thermal stability of the equipment base material is poor, thermal deformation is prone to occur, which in turn affects the cutting accuracy. The coefficient of thermal expansion of granite is extremely low, only one third of that of common metals, and its thermal conductivity is only one fortieth of that of common metals. During the LCD/LED laser cutting process, even if the local temperature changes sharply, the granite base can maintain dimensional stability, avoiding laser focus shift caused by thermal deformation, ensuring that parameters such as cutting depth and width remain precise at all times, and guaranteeing the consistency and stability of cutting quality.
Reduce the risk of resonance and enhance production safety
When the vibration frequency of the equipment is close to the natural frequency of the external environment or its own components, resonance may be triggered. This not only seriously damages the cutting accuracy but also poses a safety threat to the equipment and the operators. The natural damping characteristics of granite can effectively change the vibration frequency of equipment and reduce the probability of resonance occurrence. On the large-scale laser cutting production line of LED modules, the granite base can ensure the stable operation of the equipment, reduce unexpected shutdowns or equipment failures caused by resonance, and provide a strong guarantee for safe production.
The natural damping characteristics of granite play a crucial role in LCD/LED laser cutting from multiple dimensions such as precision guarantee, equipment lifespan, thermal stability and production safety, helping enterprises enhance their competitiveness in the high-end display manufacturing field and produce higher-quality products.
