Swiss-type CNC components are high-precision, close-tolerance micro-parts engineered for medical devices, surgical instruments, and diagnostic equipment. Utilizing sliding-headstock Swiss lathes, these components are designed for complex geometries with high length-to-diameter ratios, thin walls, and intricate internal features.

Our manufacturing floor integrates multi-axis Swiss turning with live-tool milling, enabling complete, single-setup machining of complex medical parts. This capability eliminates workpiece deflection and repositioning errors, ensuring strict concentricity and dimensional stability. Designed for OEMs requiring uncompromising precision, our production workflows maintain full material traceability and clean surface integrity essential for medical device compliance.

Key Features

Exceptional Dimensional Accuracy: Sliding-headstock guide bushing technology supports the workpiece directly at the tool cutting point, eliminating deflection on slender parts.

High Batch Repeatability: Closed-loop tool wear compensation and rigid machine construction maintain consistent tolerances from part 1 to part 10,000.

Complex Geometry Integration: Simultaneous turning, milling, and cross-drilling in a single operation, reducing multi-process tolerance stack-up.

Optimized for Small-to-Medium Batches: Quick changeover setups on Swiss machines make clinical trial batches and volume production economically viable.

Superior Surface Integrity: Minimized tool chatter and high-pressure coolant delivery yield burr-free edges and controlled surface finish parameters (Ra).

Tight Tolerance Control: Reliable execution of micro-diameters, intricate internal threads, and deep blind holes required in surgical hardware.

Applications

Automotive: Miniature actuator pins, high-pressure fuel system micro-valves, and sensor housings.

Medical: Orthopedic bone screws, spinal fixation rods, surgical stapler components, dental implant abutments, and pacemaker micro-connectors.

Lead Time: Prototypes delivered in 7 to 15 business days; production batches scheduled per confirmed forecast (typically 3 to 6 weeks).

FAQ

Q: What is your Minimum Order Quantity (MOQ)?

A: Prototypes start at 1 piece, while production batches typically start at 100 pieces to offset setup efficiencies on Swiss CNC machines.

Q: What is the tightest tolerance you can hold?

A: We routinely achieve dimensional tolerances down to +/- 0.005 mm and positional tolerances within +/- 0.003 mm, depending on material hardness and part geometry.

Q: Do you provide material certificates?

A: Yes. Every shipment includes full Mill Test Certificates (MTC) and dimensional inspection reports ensuring complete material and manufacturing traceability.

Q: Can you machine customer-supplied proprietary materials?

A: Yes, provided the material is accompanied by certified mill test reports and is compatible with our Swiss lathe bar-feed mechanisms.

Q: What file formats are required for quoting?

A: Please provide a 2D PDF drawing containing GD&T tolerances alongside a 3D CAD model (STEP or IGES format).

Q: Do you sign NDAs to protect intellectual property?

A: Yes. We routinely execute mutual Non-Disclosure Agreements (NDAs) prior to receiving detailed engineering drawings and proprietary part specifications.

Q: What is the standard production lead time?

A: Standard lead times range from 3 to 6 weeks depending on material availability, part complexity, and required secondary surface treatments.
