Bring Your Ideas to Life with Prototype Machining
At Gross Machining in Phoenix, AZ, Kent Gross specializes in prototype machining services that help inventors, startups, and established manufacturers test designs and prove concepts before committing to full production. Using advanced precision machining techniques, Kent transforms CAD drawings, sketches, or even rough ideas into functional prototypes that you can test, evaluate, and refine.
As a Proudly American Machinist, Kent understands that prototyping is about more than just making parts - it's about problem-solving and innovation. Kent works directly with you to understand your design intent, offers practical machining feedback, and delivers Made in the USA prototypes with the quality and precision needed for meaningful testing. No job too big or too small - whether you need a single proof-of-concept part or multiple prototype iterations, Kent provides the expertise and flexibility you need.
Rapid Prototype Development
Fast turnaround on prototype parts so you can test designs quickly. Manual machining allows flexibility to make design changes on the fly without expensive tooling.
- Quick turnaround times
- Work from CAD files or sketches
- Design feedback and suggestions
- Flexible design modifications
Functional Prototypes
Prototypes machined from actual production materials so you can perform real-world testing. Not just visual models - functional parts that work like the final product.
- Production material options
- Real-world testing capability
- Accurate fit and function
- Production-ready quality
Iterative Design Support
Multiple prototype iterations to refine your design. Kent works with you through design changes and improvements until you have a prototype that's ready for production.
- Multiple design iterations
- Design refinement support
- Machining feasibility feedback
- Cost optimization suggestions
Transition to Production
Once your prototype is proven, Kent can help transition to small or medium production runs. Seamless path from prototype to production parts.
- Small to medium run production
- Consistent quality control
- Same machinist, same quality
- No need to find new vendor
Prototype Applications
Product Development
Test new product designs before investing in production tooling. Validate fit, function, and performance with real prototypes.
Proof of Concept
Turn ideas into physical prototypes to prove concepts, demonstrate functionality, and secure funding or approvals.
Design Validation
Verify that designs meet specifications and requirements before committing to expensive production runs.
Fit Testing
Check how new parts fit with existing assemblies and components. Identify interference issues early.
Market Testing
Create functional prototypes for market research, customer feedback, and trade show demonstrations.
Custom Solutions
Develop custom solutions for unique problems. Prototype specialized tools, fixtures, or one-off components.
