Additionally, numerous new technological electromechanical products, including micro-electromechanical systems (MEMS), require enhanced precision and reduced scale to elevate overall mechanical manufacturing standards, resulting in significant improvements in product quality, performance, and reliability.
Precision machining and microfabrication technologies integrate multiple disciplines including mechanical engineering, electrical engineering, optics, computer control technology, and new materials science. Among various materials, natural granite has gained increasing attention due to its unique properties. Utilizing high-quality stone materials like natural granite for precision mechanical components represents a new development direction in precision measuring instruments and machinery manufacturing.
Advantages of Granite in Precision Engineering
Key Physical Properties
Granite exhibits exceptional characteristics ideal for precision engineering applications, including: low thermal expansion coefficient for dimensional stability across temperature variations, Mohs hardness rating of 6-7 providing superior wear resistance, excellent vibration damping capabilities to minimize machining errors, high density (3050 kg/m³) ensuring structural rigidity, and inherent corrosion resistance for long-term performance in industrial environments.
Industrial Applications
These material advantages make granite indispensable in critical precision applications such as: coordinate measuring machine (CMM) bases requiring exceptional flatness, optical instrument platforms demanding stable vibration-free surfaces, machine tool beds needing long-term dimensional stability, and precision measuring tables essential for accurate industrial inspection processes.
Key Development Trends
Technical Advancements
The development of granite surface plates and components reflects several prominent trends in ultra-precision machining: increasingly stringent requirements for flatness and dimensional accuracy, growing demand for customized, artistic, and personalized products in small-batch production runs, and expanding specifications with some workpieces now reaching dimensions of 9000mm in length and 3500mm in width.
