Precision Granite Beam

The ZHHIMG® Precision Granite Beam is a structural component designed to provide outstanding dimensional stability and rigidity for high-end precision equipment. Made from premium ZHHIMG® black granite (density ~3100 kg/m³), this beam delivers superior mechanical and thermal properties compared with conventional black granite or cast iron alternatives.

It is widely used as a machine base, crossbeam, or support structure in ultra-precision industries such as semiconductor, CNC machining, metrology, and optical inspection.

●  Exceptional Stability – High density and uniform texture of ZHHIMG® black granite ensure minimal deformation over time.
●  High Precision Machining – Surfaces can be lapped to achieve flatness within 1–2 µm depending on application.
●  Thermal Resistance – Low coefficient of thermal expansion provides accuracy even under varying temperature conditions.
●  Long Service Life – Non-rusting, wear-resistant granite extends operating life compared with cast iron beams.
●  Custom Design – Available with threaded inserts, weight-reducing slots, and mounting holes for assembly with guideways, linear motors, or air bearings.
●  Compliance with Global Standards – Produced according to DIN, ASME, JIS, GB, BS, GGG-P-463C standards.
