Frequently Asked Questions (FAQ)

What tolerances can you reliably achieve on micro-components versus large structural parts?

Utilizing our high-speed 24,000 RPM spindles and Heidenhain closed-loop systems, we can hold ultra-tight tolerances of ±0.005 mm on micro-components (such as medical implants). For larger industrial structures up to 500mm, we maintain a highly precise tolerance of ±0.01 mm, ensuring perfect alignment in your final assemblies.

How do you handle material certification and traceability for aerospace or medical applications?

We provide full lifecycle traceability for all critical components. This includes supplying mill test certificates (per EN 10204 3.1) to verify raw material composition. Furthermore, we utilize QR-code labeling that links to digital inspection reports and batch-specific process logs, ensuring you have the documentation required for regulatory compliance.

Can your facility process high-hardness materials or heat-resistant superalloys?

Yes. We have specialized tooling and machining strategies to handle high-hardness materials ranging from HRC 40 to 60. By employing advanced carbide tooling and coolant-through spindles, we efficiently machine tough materials, including titanium (Ti-6Al-4V) and heat-resistant aerospace alloys like Inconel 718 and Hastelloy X, without compromising the material's structural integrity.

What is the typical lead time for a custom prototype versus a low-volume production run?

We prioritize speed without sacrificing quality. Custom prototype orders are typically completed within 3 to 5 days. For low-to-medium volume production runs (100 to 10,000 parts per month), our AI-driven scheduling and automated tool changers allow us to minimize setup times, ensuring rapid and predictable delivery schedules tailored to your inventory needs.

How does your Design for Manufacturability (DFM) support reduce overall production costs?

Our engineering team conducts a free, comprehensive analysis of your CAD files (SolidWorks/STEP) within 24 hours of submission. We identify complex geometries that are difficult or slow to machine and suggest optimized alternatives. This proactive DFM process reduces machine time, minimizes material waste, and lowers tooling costs, ultimately driving down your price per unit while maintaining part functionality.
