Granite components serve as foundational elements in diverse industries:
- CNC Machine Bases: Granites high damping ratio (7-9%) reduces vibration-induced errors in high-speed machining.
- Aerospace Inspection: Granite surface plates (flatness <5μm over 2000×1000mm) calibrate CMMs for turbine blade profiling.
- Petrochemical Equipment: Corrosion-resistant granite bearings operate in acidic environments (pH <3) with negligible wear.
- Medical Devices: Laser-cut granite jigs ensure sub-micron alignment in CT scanner assembly.
A case study at a major automotive OEM found that granite-based welding fixtures reduced panel gap variability by 60% compared to steel alternatives.
