Precision Granite Base with Linear Guide System

Integrated Granite & Motion System

Unlike conventional metal frames that require secondary machining and alignment, ZHHIMG® integrates precision linear guide interfaces directly into the granite structure, ensuring:

•   Superior geometric accuracy from a single reference datum

•   Reduced assembly tolerance stack-up

•   Improved straightness and parallelism of motion axes

•   Shorter machine build cycles

•   Long-term structural stability without deformation

This integration is especially critical for ultra-precision positioning systems where micron-level deviations affect overall machine accuracy.

High-Density Natural Granite Structure

Manufactured from proprietary ZHHIMG® high-density black granite, the base delivers:

•   Outstanding thermal stability for temperature-sensitive environments

•   Excellent vibration damping for smoother motion performance

•   High compressive strength for heavy-load applications

•   Corrosion-free and rust-proof structure
•   Non-magnetic and electrically insulating properties

Compared with cast iron or welded steel frames, granite maintains its geometric integrity over decades of continuous operation.

Precision Linear Guide Interfaces

The granite base features precision-machined mounting surfaces and embedded threaded inserts, enabling accurate installation of:

•   Linear guide rails

•   Ball screw supports

•   Linear motor stators

•   Air bearing motion systems

•   Optical alignment modules

All mounting surfaces are processed through ultra-precision grinding and manual lapping to guarantee flatness and positional accuracy.
