Precision Granite Mounting Block with Machined Through-Holes | ZHHIMG®
Engineers typically spec this kind of granite mounting block wherever a sensor, fixture, or positioning stage needs a rigid, thermally stable interface point — underneath optical inspection heads on AOI lines, as a mounting interface for air bearing stage components, inside CMM fixture assemblies, or as a stable riser block within larger granite base assemblies for semiconductor and battery inspection equipment. In each case, the requirement is the same: whatever sits on top of this block needs the block itself to be a non-variable in the measurement or positioning chain.

Precision Granite Mounting Plate
- Material: Black precision granite, fine-grained and uniformly dense — no visible pitting, veining, or color inconsistency across the surface
- Finish: Matte-to-satin ground finish on the top working surface, engineered for consistent optical and mechanical reference rather than decorative shine
- Mounting holes: Four symmetrically placed counterbored through-holes, allowing flush-mount bolting without the bolt head protruding above the reference surface
- Edges: Clean, chamfered edges to prevent chipping during handling and installation
- Packaging: Reinforced aluminum carrying case with contoured foam insert, protecting both the working surface and the mounting holes during transport and storage

Precision Granite Square
Reliable measurement begins with reliable references.
When precision machinery depends on geometric accuracy, stable reference standards prevent error accumulation across the entire manufacturing chain. Granite metrology tools are trusted because they preserve their geometry over years of use, even in demanding industrial environments.
For engineers and quality specialists, confidence in measurement starts with choosing the right reference artifact.
