ZHHIMG® Precision Granite Square Ruler with Protective Carrying Case
A machine can have highly accurate linear scales, precision guideways and advanced control software, yet a small squareness error between two axes can still affect the final result.
That is where a precision square becomes useful.
A granite square provides a physical geometric reference against which a machine axis, fixture, workpiece or structural component can be inspected. Combined with a calibrated dial indicator or other suitable metrology equipment, it can be used to identify deviations from the intended 90° relationship.

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
