Granite Assembly

Granite Assembly

Integrated Systems Built on a Foundation of Stability

A Granite Assembly is a purpose-built,integrated structure where precision granite components form the primary,stable framework for mounting,aligning,and operating other mechanical,optical,or electronic systems.It is not a single part,but a engineered system that leverages granite's inherent properties to create an ultra-stable,unified platform for high-precision applications.

Core Concept&Advantage

The assembly combines multiple granite elements(plates,rails,blocks)and often incorporates metal or composite sub-components into a single rigid structure.The key advantage is that the entire assembly benefits from granite's uniform thermal response,exceptional vibration damping,and permanent geometric integrity across all its critical interfaces.

Typical Configurations

Multi-Axis Motion Systems:An assembly consisting of a granite base plate,perpendicular granite ways(rails),and granite or composite carriages to create an X-Y or X-Y-Z stage for precision positioning(e.g.,in wafer inspection or laser writing).

Metrology Bridge Structures:A granite bridge and column assembly for a Coordinate Measuring Machine(CMM)or vision system,where the granite's stability ensures consistent measurement accuracy across the working volume.

Optical Bench&Instrument Platforms:A large granite base("breadboard")with a precisely machined grid of mounting holes,integrated with granite risers,optical posts,and kinematic mounts to create a vibration-isolated platform for lasers,lenses,and sensors.

Machine Tool Sub-Assemblies:Complex fixtures such as a granite pallet changer system,a rotary indexing table base,or a dedicated machining center tombstone for holding multiple workpieces with micron-level repeatability.

Calibration&Reference Assemblies:Custom-built setups incorporating granite surface plates,master straightedges,angle blocks,and reference mirrors into a single,calibrated unit for in-house metrology.
