Precision Medical CNC Machining for Difficult Alloys
When developing medical devices, surgical instruments, or diagnostic equipment, you need more than just a machine shop. You need a manufacturing partner who understands strict geometric tolerances, biocompatible materials, and rigorous documentation.
At AXALLOY Precision, we specialize in medical CNC machining, focusing on complex, high-value components made from difficult-to-machine alloys. From initial engineering prototypes to controlled low-volume and repeat production, we provide the process control and traceability your engineering and quality teams require.
What You Get When Partnering With Us
We know that in the medical industry, a delayed prototype or a missing material certificate can derail your entire project schedule. Here is how our approach directly benefits your team:
Faster Validation and Time-to-Market
We don't just offer "fast delivery." Our 10–20 business day standard lead times (and 5–10 days for prototypes) mean your design validation, functional testing, and clinical trial preparations happen on schedule, accelerating your product's time-to-market.
Reduced Supply Risk
Your quality team receives parts that pass incoming inspection the first time. Every shipment is backed by the exact documentation you need for compliance, including Material Test Reports (MTRs), Certificates of Conformance (CoC), and First Article Inspection (FAI) reports.
Actionable Engineering Support
Before we cut any metal, our engineers review your drawings. You receive direct Design for Manufacturability (DFM) feedback, ensuring that complex contours, thin walls, and critical interfaces are actually manufacturable without driving up your unit costs.
Consistent Repeatability
By utilizing multi-axis milling and mill-turn centers, we machine complex medical parts with fewer setups. This preserves critical feature relationships and guarantees that part #500 is identical to part #1.
Biocompatible and Difficult-Alloy Expertise
Medical CNC machining often involves tough, work-hardening, or gummy materials. We evaluate material behavior, geometry, and surface requirements before defining the machining process.
We routinely machine the following medical-grade alloys:
-
✓
Titanium Alloys: Grade 2, Grade 5 (Ti-6Al-4V), and Grade 23 (ELI) for implants and bone screws.
-
✓
Stainless Steels: 316L, 17-4 PH, and 15-5 PH for surgical instruments and structural device components.
-
✓
Cobalt Alloys: MP35N and Cobalt Chrome for high-strength, wear-resistant medical applications.
-
✓
Specialty Metals: Nitinol and high-nickel alloys (Inconel, Hastelloy) for specialized medical and diagnostic equipment.
Our Material Qualification Process
Every material we machine is verified against strict medical-grade specifications before production begins. Our process includes:
- › Material composition verification via MTR review
- › Work-hardening behavior analysis for optimal tool paths
- › Surface finish validation for biocompatibility requirements
- › Heat treatment and passivation coordination
