Precision Granite Machine Base — Gantry-Style Structural Frame
What you're looking at is not a slab of stone — it's a fully engineered structural system. This precision granite gantry base combines three functional zones in a single monolithic assembly: a vertical mounting wall with integrated cable-management channels, an open bridge section that spans the working envelope, and a dense-grid mounting table ready to accept your stage, sensor, or tooling hardware.
If you've ever asked "can granite replace a welded steel gantry frame?" — the honest engineering answer is: for any application where thermal drift, vibration, or long-term creep would compromise your measurement or process accuracy, granite isn't just a substitute. It's the upgrade.

Zero long-term creep. Welded steel structures relieve internal stress over months or years, gradually shifting geometry. A granite monolith doesn't do this — what you measure at installation is what you get five years later.
Superior vibration damping. The crystalline grain structure of granite absorbs mechanical vibration far more effectively than steel's ordered lattice, which conducts vibration instead of dissipating it. For any application involving optical alignment, metrology, or high-speed motion, this translates directly into cleaner data and tighter process control.
Thermal stability that doesn't fight your tolerances. A 1°C swing across a 1-meter steel structure can move dimensions by nearly 12 micrometers. Granite's lower, more predictable thermal expansion means your gantry geometry stays where you put it — even as ambient shop temperature drifts through a normal workday.
Single-piece monolithic integrity. No welds, no bolted joints between the bridge and the base, no hidden stress concentrations. The entire load path — from mounting table through bridge arm to back wall — is one continuous piece of stone.
Cleanroom and semiconductor compatibility. Non-magnetic, non-outgassing, and dimensionally inert — properties that matter the moment your application moves anywhere near linear motors, optical paths, or particle-sensitive environments.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Can the mounting hole pattern be customized?
Yes. Hole diameter, thread type, spacing, and depth are all configured to your drawing or CAD file. The grid shown is one of many standard layouts we produce.
What's the largest single piece you can manufacture?
Our production equipment handles single components up to 20 meters in length, 4000 mm in width, and 1000 mm in thickness, with crane capacity up to 100 tons per piece.
How do you guarantee flatness on a structure this complex, not just a flat plate?
Each functional surface — the mounting table, the bridge underside, the back panel — is independently lapped and verified using laser interferometry and electronic levels calibrated to traceable national standards.
Is this suitable for cleanroom installation?
Yes. Granite is non-outgassing and non-particle-shedding when properly sealed and finished, and we can supply documentation to support your cleanroom qualification process.
What's the typical lead time for a custom configuration like this?
Lead time depends on size, complexity, and current production load. Share your drawing and we'll provide a specific timeline with your quote.
