Precision Granite Machine Base with Vertical Structural Frame

At the heart of this product is ZHHIMG® high-density black granite, with a density of approximately 3100 kg/m³. This material is specifically selected for precision engineering rather than architectural use.

Key material advantages include:

•   Exceptional dimensional stability with extremely low thermal expansion

•   Natural vibration damping without additional damping layers

•   No internal stress, no aging deformation, and no need for stress relief

•   High stiffness and excellent load-bearing capability

Some low-cost suppliers replace granite with marble to reduce material costs. ZHHIMG® firmly opposes this practice. Marble lacks the mechanical strength and thermal stability required for precision machine bases and is unsuitable for high-accuracy industrial systems.

Structural Design & Product Characteristics

This granite machine base is designed as a load-bearing reference structure, optimized for precision alignment and repeatability.

Notable design features include:

•   Precision-ground top and side reference surfaces

•   High perpendicularity and parallelism between base and vertical frame

•   Integrated mounting holes and threaded inserts for direct equipment installation

•   Internal weight-reduction cavities to improve stiffness-to-mass ratio

•   High-strength granite bonding technology ensuring long-term structural integrity

The structure can be customized in size, geometry, and interface design to match specific equipment requirements, including large-format and high-load applications.
