Product Description
Custom Precision Granite Beam for Precision Equipment
A precision component has to fit more than a drawing outline. It must also work with the assembly datums, mounting interfaces and inspection requirements that define the finished machine.
UNPARALLELED® offers custom precision granite components for equipment builders seeking drawing-defined structural parts. The component shown features an elongated beam profile, a stepped end section, large circular openings and smaller interface holes. Its geometry provides a starting point for discussing a custom granite beam-not a fixed specification for every application.
Send us your component drawing, critical tolerances and intended application. We will review the requirements with you before confirming the manufacturing scope and quotation.
A Granite Component Built Around Your Assembly
An overall length and width are only part of the specification. Which face establishes the assembly datum? Where will the component be supported? Which interfaces must align with the surrounding hardware?
These questions belong at the beginning of a custom project.
For the pictured design, the stepped profile and hole arrangement are prominent features. Their final purpose-whether locating, fastening, providing clearance or accommodating another assembly requirement-should be defined in the approved drawing. We do not assume the function of a feature from its appearance alone.
The aim is straightforward: agree on what matters before manufacturing begins, then inspect against that agreement.
The photograph is a design reference. Numerical specifications must be confirmed through the quotation and drawing-review process.

Drawing-Defined Structural Geometry
Specify the component around the space and interfaces available in your machine. The pictured part illustrates an elongated body with a stepped section and multiple openings; the supplied design should follow the approved project drawing.
For the buyer, this creates a clear basis for discussing fit, assembly access and the relationship between the granite component and adjacent parts.
Clearly Identified Functional Surfaces
Not every face performs the same job. Identify the reference faces, mounting surfaces and any precision guiding surfaces separately in your drawing.
This allows the quotation and inspection plan to address the surfaces that matter to the assembly, without treating every face as if it requires an identical finish or tolerance.
Defined Interfaces Rather Than Assumed Details
Hole locations, insert requirements, thread types and mating hardware should be reviewed together.
If threaded interfaces are required, provide the mating-part information and relevant loading requirements. The final interface design and supply scope must be confirmed before manufacture.
An Agreed Basis for Inspection
State the required geometric characteristics and datum references at the RFQ stage. Where support arrangement or measurement conditions are relevant to acceptance, include those requirements as well.
A shared inspection basis helps the customer and supplier evaluate the same characteristics rather than relying on an undefined claim of "high precision."

FAQ
Is the photographed product a complete air-bearing stage?
No complete stage is visible. The photograph shows a standalone granite component without a visible carriage, drive system or assembled air-bearing system. Any additional components must be listed separately in the quotation.Granite-Air-Bearing-Guideways.jpg
Can I order a different size or hole pattern?
Submit the required geometry for review. Overall dimensions, stepped sections, openings and interfaces need to be assessed against your drawing before the manufacturing scope is confirmed.
What accuracy can UNPARALLELED provide for this component?
The image does not establish a numerical accuracy specification. Send the required flatness, straightness, parallelism, perpendicularity and surface-finish requirements, identifying the relevant faces and datums. Achievable values and the inspection scope must be confirmed for the final design.
Can the component include threaded inserts?
Include the required thread specification, insert locations, mating hardware and relevant loading information in your inquiry. Insert material, installation details and feasibility are subject to technical confirmation.
Can this granite beam be used as an air-bearing guideway?
Potentially, but not on the basis of appearance alone. The working surfaces must satisfy the requirements of the selected bearing arrangement, including the relevant geometric and surface-finish specifications. These requirements are application-specific.euspen+1
How will the component be inspected?
The inspection plan should follow the agreed drawing and acceptance criteria. Tell us which measurements and report details you require so that the inspection scope can be included in the quotation.
