Granite precision manufacturing: The all-round cornerstone from the microscopic world to the vast universe.

On the stage of precision manufacturing, granite, thanks to its unique properties bestowed by geological changes over hundreds of millions of years, has transformed from an unremarkable natural stone into a "precision weapon" of modern industry. Nowadays, the application fields of granite precision manufacturing are constantly expanding, and it is playing an irreplaceable role in various key industries with its outstanding performance.
I. Semiconductor Manufacturing: Building a "Solid Fortress" for Chip Precision
In the semiconductor industry, the manufacturing precision of chips has reached the nanometer level, and the requirements for the stability and precision of production equipment are extremely strict. Products precisely manufactured from granite have become the core components of semiconductor manufacturing equipment. As the "heart" of chip manufacturing, the lithography machine has extremely high requirements for the stability of its nano-scale positioning platform on the base. Granite has an extremely low coefficient of thermal expansion, approximately 4.61×10⁻⁶/℃, which can effectively resist minor fluctuations in environmental temperature during the photolithography process. Even if the temperature in the production workshop changes by 1℃, the deformation of the granite base is negligible, ensuring that the laser of the photolithography machine can be precisely focused to engrave fine circuit patterns on the wafer.

In the wafer inspection stage, the reference module made of granite is also indispensable. Even the slightest defect on the wafer surface can lead to a decline in chip performance. However, the granite reference module, with its extremely high flatness and stability, provides an accurate reference standard for inspection equipment. The granite platform manufactured by the five-axis linkage nano-grinding technology can achieve a flatness of ≤1μm/㎡, enabling the detection instrument to precisely capture the minute defects on the wafer surface and ensuring the yield of chips.
Ii. Aerospace: The "Reliable Partner" for Escort Aircraft
The aerospace field has extremely strict requirements for the reliability and accuracy of equipment. Granite precision manufacturing products have played a significant role in satellite inertial navigation test benches and spacecraft component inspection fixtures. Satellites operate in space and need to rely on high-precision inertial navigation systems to determine their positions and attitudes. The inertial navigation test bench made of granite, with its high hardness and strength, can withstand the rigorous tests in complex mechanical environments. During the test process simulating extreme temperatures and intense vibrations in space, the granite test bench remained stable throughout, providing a solid foundation for the precise calibration of the inertial navigation system.

Granite inspection fixtures also play an important role in the inspection of spacecraft components. The dimensional accuracy of spacecraft components directly affects the overall performance and safety of the spacecraft. The high precision and stability of the granite inspection fixture can ensure the accurate detection of the size and shape of the components. Its dense internal structure and uniform material prevent detection errors caused by the deformation of the tooling itself, ensuring the smooth launch and safe operation of the spacecraft.
Iii. Medical Research: The "Stable Cornerstone" for Precision Medicine
In the field of medical research, large medical equipment such as CT and MRI have extremely high requirements for the stability of the base. When patients undergo scanning examinations, even slight vibrations of the equipment may affect the clarity and accuracy of the images. The equipment base precisely made of granite, with its excellent vibration absorption performance, can effectively reduce the vibration interference generated during the operation of the equipment. The weak friction between the mineral particles inside acts like a natural shock absorber, converting the vibration energy generated during the operation of the equipment into heat energy and dissipating it, thus keeping the equipment stable during operation.

In the field of biological detection, the granite stage provides stable support for the detection of experimental samples. The detection of biological samples often needs to be carried out under high-precision instruments, and extremely high requirements are placed on the flatness and stability of the stage. The high-precision surface of the granite stage can ensure that the sample remains in a fixed position during the detection process, avoiding deviations in the detection results caused by the unevenness or shaking of the stage, providing reliable data support for medical research and disease diagnosis.
Iv. Intelligent Manufacturing: The "Secret Weapon" for Enhancing the Precision of Automation
With the rapid development of intelligent manufacturing, industrial robots and automated inspection systems have increasingly higher requirements for precision. The calibration base precisely manufactured from granite has become the key to the accuracy calibration of industrial robots. After long-term operation, the positioning accuracy of the mechanical arm of industrial robots will deviate, affecting production efficiency and product quality. The granite calibration base, with its extremely high precision and stability, provides an accurate reference for the calibration of robots. By comparing with the granite calibration base, technicians can quickly detect the precision error of the robot and make precise adjustments to ensure that the robot can complete high-precision production tasks according to the preset program.

In the automated inspection system, granite components also play an important role. Automated inspection equipment needs to conduct rapid and accurate inspections on products, which requires that all components of the equipment have extremely high stability. The addition of granite components has effectively enhanced the overall performance of the automated inspection system, enabling it to maintain stability during high-speed operation, accurately identify product defects and errors, and improve the quality control level of the products.

From the micro semiconductor chip manufacturing to the vast aerospace field, and then to the medical research related to human health and the booming intelligent manufacturing, granite precision manufacturing is shining brightly in various industries with its unique charm and outstanding performance. With the continuous advancement of technology, the application fields of granite precision manufacturing will continue to expand, contributing more to promoting the high-quality development of the global manufacturing industry.
