Selection Comparison and Application Principles of Granite Guides and Machine Tool Bases in Precision Engineering In preciachine tools, CMMs, grinders, optical equipment, and semiconductor equipment, the selection of granite vs. cast iron vs. steel bases & guides revolves around core factors: precisin retention, vibration resistance, thermal deformation, long-term stability, and machining conditions. I. Why Precision…

Precision granite serves as the physical cornerstone of high-precision metrology. Leveraging its extreme stability from natural aging, ultra-low thermal expansion, high damping vibration damping, and wear/corrosion resistance, it has become an irreplaceable reference material in modern precision measurement and high-end manufacturing, widely applied in core scenarios such as Coordinate Measuring Machines (CMMs), semiconductor lithography stages,…
