SUPPLY SCOPE

Built around the requirements
of your assembly.

The supply scope combines the manufacturing route, inspection requirements and delivery requirements for your component.

Part specification

Finish	Specified per drawing; masking agreed before processing
Inputs	Controlled drawing, model, quantity and critical dimensions
Status	Illustrative concept, not a catalog component
Process	Casting and secondary machining, as applicable
Material	Aluminum alloy, subject to review
Inspection	Project-specific dimensional and documentation scope
Interfaces	Mounting face, locating diameters and shaft or bearing interfaces

Pricing, tooling, quantities and lead time are quoted for the individual project.

Key interfaces

Bearing bores, axial locating faces, concentric features and bolt patterns.

Surface treatment

Specify bore and mating-face condition separately from the exterior finish. Confirm masking requirements before coating.

Inspection requirements

Identify fit requirements and datum relationships. Agree how bores, mounting faces and related critical features will be measured.

Detailed technical description & project notes

Application and interfaces

Motor end caps connect the motor structure to critical locating and rotating interfaces. Our project review focuses on the relationship between the mounting face, locating diameter, bearing interface and shaft opening. Drawing-controlled fits and geometric requirements guide the machining route and the inspection setup.

Manufacturing route

VelnoCast brings aluminum casting, CNC machining and finishing into a coordinated component supply process. We review recurring quantities, geometry and functional requirements to define a suitable route. For cast components, the review covers draft, parting direction, wall transitions and machining stock. For machined components, it covers access, fixturing and the relationship between critical features.

Critical characteristics

Identify the features that control fit, alignment, sealing and assembly. Separate these from cosmetic requirements so each can be addressed with an appropriate production and inspection method. Drawing revision, material specification and reference datums provide the common basis for the quotation, sample review and production record.

Surface and assembly readiness

Specify visible areas, coating requirements and interfaces to be masked. Threads, grounding contacts and sealing faces need particular attention when surface treatments are involved. Include deburring, cleanliness and packaging expectations in the drawing package, especially for components that enter an assembly directly.

Inspection and release

Our quality review connects the important characteristics to an inspection method and the records required for acceptance. Discuss sample approval, dimensional reporting, material documentation and batch identification before production release. Agreed acceptance criteria govern the specific project.

Start your project

Send the current drawing, a compatible 3D model where available, the required alloy and initial and annual quantities. Include target milestones and open engineering questions. Our team uses these inputs to clarify the technical scope and prepare a project-specific proposal.

WHAT TO MEASURE ON THIS PART

End-cap inspection: the bore is only part of the fit.

Use these features to build the inspection scope for your drawing. The illustrated geometry is an example, not a stocked or validated product.

Feature	Requirement to define	Check / evidence
Bearing seat	Bore size, form and required surface texture.	Suitable bore measurement, drawing-defined form evaluation and texture check.
Flange / bore relationship	Perpendicularity, position or runout as actually specified.	CMM or suitable geometric measurement using the specified datum system.
Bolt pattern	Hole size, location, counterbore and fastener clearance.	Coordinate or functional-gauge inspection appropriate to the tolerance.
Final condition	Clean bores, burr-free edges and correctly masked fits.	Visual and dimensional checks after operations that can affect acceptance.
