Application Industry FAQs
Common questions about selecting granite components by industry.
What granite components are used in CMMs?
CMMs typically use granite surface plates, bases, bridges, columns, and guide rails. Accuracy usually reaches Grade 00 or Grade 000, with flatness of 2–10 μm, inspected in a temperature-controlled environment with laser interferometers or electronic levels.
Why do semiconductor inspection tools use granite bases?
Semiconductor inspection and measurement equipment demand extremely low vibration, thermal drift, and long-term stability. Granite's low thermal expansion, vibration damping, and non-magnetic properties provide a stable sub-micron reference for wafer inspection and probe stations.
What flatness is needed for optical inspection platforms?
Optical inspection platforms need high flatness and low surface roughness (Ra ≤ 0.4 μm) with stable vibration damping. Vision measuring systems and machine-vision platforms may also need integrated guide rails or air-bearing holes.
What are the benefits of granite beds for machine tools?
Granite machine-tool beds offer excellent vibration damping, thermal stability, and resistance to deformation, making them suitable for precision grinding machines and machining centers. Large beds also require careful evaluation of machining, aging, and shipping constraints.
