Why do precision machinery manufacturing choose granite as a component material?

 

Precision machinery manufacturing is a field that requires the highest precision and reliability. Granite is one of the most popular materials in the industry. Granite was chosen as the component material because of several compelling factors that enhance the performance and service life of precision machinery.

First, granite is known for its exceptional stability. Unlike metals, which expand or contract with temperature fluctuations, granite maintains its dimensions in varying environmental conditions. This dimensional stability is crucial for precision machinery, as even the slightest deviation can lead to significant errors in the manufacturing process.

Secondly, granite has excellent rigidity and strength. Its dense structure allows it to withstand heavy loads without deformation, making it ideal for use on machine bases and components that require a solid foundation. This rigidity helps minimize vibration during operation, which is critical to maintaining accuracy in precision machining.

Another significant advantage of granite is its excellent damping properties. When machinery is running, vibration is inevitable. Granite can effectively absorb these vibrations, thereby reducing their impact on mechanical properties. This feature is especially beneficial in high-speed machining applications where accuracy is critical.

In addition, granite is wear-resistant and corrosion-resistant, helping to extend the service life of mechanical components. Unlike other materials that degrade over time, granite is durable and does not require frequent replacement and maintenance.

Finally, the aesthetics of granite cannot be ignored. Its natural beauty and polished effect make it ideal for visible parts of machinery, enhancing the overall appearance of the equipment.

In summary, the choice of granite as a component material for precision machine manufacturing is a strategic decision driven by its stability, stiffness, damping properties, durability and aesthetics. These properties make granite a valuable asset for achieving the high precision standards required by modern manufacturing processes.
