The advantages of Granite air bearing parts

       In the field of high-end manufacturing and precision machining, the Granite air bearing parts  is becoming the core support of many cutting-edge technologies with its excellent performance. Here is a deep analysis of its unparalleled advantages:

       Ultra high precision positioning: The granite air floating motion platform is equipped with a 1nm resolution encoder, with a repeated positioning accuracy of ± 0.1um and a positioning accuracy of ± 0.3um. In the semiconductor chip manufacturing process, this accuracy ensures precise characterization of circuit patterns on the chip, resulting in better chip performance and higher integration. In precision optical component processing, high-precision polishing of lens surfaces can be achieved, allowing the imaging quality of optical components to reach the top level.

      Almost zero friction operation: using air as the lubricating medium, there is no mechanical contact or friction between moving parts. This greatly reduces energy loss during the movement process and extends the service life of the platform. In the micro displacement operation of precision instruments, the zero friction characteristic ensures the accuracy of displacement and avoids jamming and errors caused by friction. During the transportation of semiconductor wafers, it can prevent scratches caused by friction and improve the yield rate of wafers.

      Excellent stability: Using granite marble as the base, it has extremely high rigidity and excellent geometric characteristics. Granite has undergone billions of years of natural mechanical equilibrium, with basic disappearance of internal stress and stable internal structure, and can maintain good stability for a long time. In aerospace component processing, facing complex processing techniques and high precision requirements, its stable performance ensures that the processed components meet strict quality standards. In the manufacturing of high-end electronic devices, it can provide a stable working platform for the production process and ensure the consistency of product quality.

     Excellent straightness: Under the homogenization effect of the gas film, excellent straightness can be achieved. The thickness of the gas film is almost unaffected by speed, and creep does not occur even at extremely low speeds, making the motion very stable. In applications such as laser cutting and engraving, stable straightness ensures the accuracy of cutting and engraving lines, resulting in high surface smoothness and precision of the processed products. In the field of precision measurement, it can provide a stable linear motion reference for measuring instruments and improve measurement accuracy.

     Silent operation: Using a silent air floating guide rail and unique small hole throttling technology, it effectively solves the air hammer effect and micro fluctuations in high-pressure problems, with extremely low noise during operation. This provides an ideal working platform for laboratories, medical equipment manufacturing, and other scenarios that have strict requirements for environmental noise. In the precision testing equipment of hospitals, silent operation avoids interference with medical testing results and provides patients with a quiet medical environment.

     Clean and pollution-free: With no mechanical guide rail design, there is no need for lubrication devices or lubricating oil, and no generation of pollutants such as oil stains, providing a better solution for cleanroom level applications. In industries such as semiconductor manufacturing and biopharmaceuticals that require extremely high environmental cleanliness, its pollution-free characteristics are crucial to effectively avoid product quality problems caused by pollution. In the photolithography process of chip manufacturing, a clean working environment can ensure the accuracy of photolithography and the performance of chips.

     Good thermal stability: The shape of granite itself is minimally affected by temperature, with a very small coefficient of thermal expansion and low thermal conductivity. Under different temperature environments, the platform has good dimensional stability and can maintain high-precision operation continuously. In material processing under high or low temperature environments, thermal stability ensures that processing accuracy is not affected by temperature changes. In outdoor precision measurement work, even if the ambient temperature fluctuates greatly, the accuracy of the measurement results can be ensured.

     Error equalization function: It has the function of error equalization and can achieve higher guiding accuracy with lower manufacturing precision. This ensures the high performance of the platform while reducing manufacturing costs, enabling more enterprises to obtain high-precision motion platforms at a reasonable cost. In some production scenarios that are cost sensitive but have certain precision requirements, this feature has significant advantages and helps enterprises improve production efficiency.
