Key Advantages of UNPARALLELED® Granite Frame
High-Density Black Granite Material
The frame is produced from UNPARALLELED® Black Granite with a density of approximately 3100 kg/m³, offering significantly better mechanical stability than common commercial granites. High density ensures excellent vibration absorption and minimal deformation under load.
Outstanding Thermal Stability
Granite's naturally low coefficient of thermal expansion makes this frame ideal for precision environments. It maintains geometric accuracy even under temperature fluctuations, supporting long-term repeatability in precision equipment.
Exceptional Structural Rigidity
The integrated granite frame and base design provides high stiffness and load-bearing capacity. It is suitable for supporting heavy assemblies while preserving micron-level accuracy.
Precision Machining and Hand Lapping
All functional surfaces are CNC-machined and manually lapped by experienced technicians to achieve high flatness, squareness, and parallelism. Critical interfaces can reach micron-level tolerances, suitable for precision assembly and calibration.
True Granite – No Substitution
UNPARALLELED® strictly uses natural granite, not marble or artificial stone. This guarantees long-term stability, wear resistance, and measurement reliability, especially in high-end industrial applications.
