Manufacturing
How we make this part
Process, material options and inspection for cnc milled and turned aluminum prototypes and parts.
Each quote includes a check of how the part will be machined: which features need special tools, which tolerances drive cost, and whether small design changes could simplify production. Prototypes are machined on 3-, 4- or 5-axis mills and CNC lathes, and the process is documented so production batches repeat the approved result. Revisions can be made quickly between prototype rounds.
6061-T6 aluminum is the default for prototypes thanks to fast machining and good strength. 7075-T6 is used for high-stress parts. 304 and 316 stainless steel handle corrosion and strength requirements. Finishes such as anodizing, bead blasting, brushing and passivation can be applied to prototypes so they represent production parts accurately.
Prototypes are inspected on critical features, and production parts receive first-article inspection and in-process checks. Inspection reports and material certificates are available, and revision history is tracked so each batch matches the current drawing. Typical uses include product development prototypes, test fixtures, pilot production parts, replacement components and low-volume production for robotics, electronics and machinery.
FAQ
Frequently asked questions
How can I reduce the cost of a CNC prototype?
Use standard hole sizes and threads, avoid very deep pockets and tiny internal radii, apply tight tolerances only where needed, and choose easily machined materials like 6061 aluminum. We point out cost drivers during quoting so you can decide what to change.
Can you move from prototype to production with the same process?
Yes. We document fixtures, tools and programs used for approved prototypes, then reuse or optimize them for production. This reduces the risk of changes between prototype and production parts, and first-article inspection confirms the production setup.
How do I get a quote for cnc milled and turned aluminum prototypes and parts?
Send a 3D model (STEP or IGES) and a 2D drawing with tolerances, material, finish and quantity through the quote form or by email. An engineer replies within 24 hours on business days with price, lead time and any DFM suggestions.
