Precision Granite Component with Custom Machining

✔ Superior Material: ZHHIMG® Black Granite

●   High density (~3100 kg/m³) for excellent rigidity

●   Ultra-low thermal expansion

●   Naturally vibration-damping

●   Non-magnetic, non-corrosive, non-rusting

●   Long-term dimensional stability compared to cast iron or steel

✔ Precision Machining Capability

ZHHIMG® uses advanced CNC equipment, large-format grinders, and controlled-temperature metrology labs to ensure:

●   Flatness, parallelism, and perpendicularity at micron or sub-micron level

●   Smooth, chip-free edges

●   Precisely machined holes and recesses

●   Custom layout of threaded inserts (stainless steel, brass, or other materials)

✔ Custom Structural Design

The product shown includes:

●   Four large precision holes for mechanical mounting or optical/laser integration

●   Small metal inserts recessed below the surface, preventing interference during calibration

●   A uniform, stress-relieved granite body with high load-bearing capacity

This design ensures stability and durability even under long-term mechanical or thermal stress.
