Swiss Machining Services

XTPROTO provides Swiss CNC machining for metals and plastics, delivering micron-level precision, multi-axis turning, milling, and drilling with tight tolerances and fast, reliable production.

Custom Swiss Machining

XTPROTO manufactures high-precision, small-diameter components using advanced Swiss CNC machining. By supporting the workpiece with a guide bushing immediately adjacent to the cutting tool, we eliminate deflection and vibration, easily achieving ultra-tight tolerances up to ±0.0001 in (±0.0025 mm) and superior surface finishes on complex, high-aspect-ratio parts.Our “done-in-one” multi-axis setup integrates turning, milling, cross-drilling, and slotting into a single automated cycle—slashing lead times and ensuring absolute consistency. From medical-grade titanium and 17-4 PH stainless steel to high-performance PEEK, we deliver scalable, cost-effective custom manufacturing for the aerospace, medical, and electronics industries.

What Is Swiss Machining？

Swiss machining is an ultra-precision manufacturing process engineered for small, complex, and slender components. It utilizes a sliding headstock to feed raw stock through a guide bushing past stationary tools, delivering micron-level accuracy and multi-axis turning, milling, and cross-drilling in a single, continuous setup.

Swiss CNC Machining Capabilities

Our facility utilizes advanced 8-axis Swiss-type lathes equipped with up to 32 live tools and automated bar-feeders. We specialize in machining micro-to-small parts ranging from Ø0.012 in to Ø1.25 in (0.3 mm to 31.75 mm) in diameter, and up to 30 in (762 mm) in length. By synchronizing front- and back-working, we execute complex multi-surface milling, cross-drilling, slotting, and precision thread-whirling in a single automated operation. This configuration allows us to consistently hold linear tolerances of ±0.0005 in (and up to ±0.0001 in for critical features) across high-performance alloys (Titanium, 17-4 PH, Inconel) and engineering plastics (PEEK).

Solving The Industry’s Toughest Swiss Machining Challenges

Micro-Vibrations & Part Flex on Slender Shafts

By keeping the cutting tool mere millimeters from the guide bushing support, our process completely absorbs lateral forces. This ensures flawless straightness, zero part flex, and ultra-smooth surface finishes on even the highest-aspect-ratio designs.

The "Tolerance Stack-up" Trap in Multi-Stage Processing

Moving delicate parts across multiple traditional machines introduces critical alignment errors. Our 8-axis simultaneous turning centers complete turning, cross-slots, and angled holes in one continuous cycle—guaranteeing perfect concentricity and ready-to-assemble components.

Continuous Precision on Extreme Alloys

Materials like Titanium and Inconel cause rapid tool wear and mid-batch dimensional drift. Our engineering team combats this through optimized toolpath geometry, rigid setups, and real-time in-process gauging, keeping microscopic tolerances unchanged from the 1st part to the 50,000th.

"Done-in-One" Multi-Axis Integration

While maintaining material precision is critical, achieving geometric accuracy on intricate geometries requires advanced multi-axis Swiss machining integration. Complex, micro-scale components often require turning, cross-drilling, and multi-surface milling. Moving these delicate parts across multiple traditional machines introduces catastrophic tolerance stack-up and critical alignment errors every time the workpiece is re-clamped. We resolve this by leveraging advanced 7- to 8-axis simultaneous Swiss CNC turning. By completing back-working, eccentric slots, and angled features in a single, continuous setup, we eliminate secondary handling errors, guarantee perfect concentricity, and slash total manufacturing lead times by up to 40%.

High-Volume Scalability

Executing these complex multi-axis configurations on a single prototype is only the first step; the real challenge lies in scaling this advanced Swiss machining process into high-volume manufacturing. Many machine shops can deliver a flawless prototype but fail to maintain timelines during massive production runs. Our facility houses over 200 high-precision CNC centers, including our specialized Star and Tornos Swiss workshop, operating across 160,000 sq. ft. of climate-controlled manufacturing space. Every Swiss lathe is integrated with automated bar-feeding systems, enabling continuous, 24/7 unmanned production. This robust capacity allows us to transition your project seamlessly from low-volume R&D samples to scheduled monthly contract manufacturing of 100,000+ units without supply chain bottlenecks.

Batch-to-Batch Dimensional Consistency

However, running 24/7 high-volume Swiss production is meaningless without strict dimensional control over the entire fleet. For critical medical implants and aerospace sensors, dimensional drift across a batch is unacceptable. When machining high-performance alloys like Titanium, 17-4 PH, or Inconel, tool wear typically causes microscopic variances over time. We combat this by utilizing the rigid sliding-headstock configuration, which supports the stock right at the cutting boundary to eliminate part flex. Operating under strict AS9100D and ISO 13485 quality systems with real-time, in-process gauging, we ensure that the critical dimensions of your 100,000th part remain identical to the first.

Swiss Machining FAQ

How do you prevent material cross-contamination when switching production between medical plastics (like PEEK) and high-performance alloys?

We enforce strict isolation protocols in our workshop. For sensitive medical polymers like PEEK, we utilize dedicated Swiss lathes or implement a rigorous, documented multi-stage deep-clean cycle of the fluid lines, enclosures, and guide bushings. Furthermore, we use separate, material-specific cutting fluids and tooling sets to guarantee that zero metallic micro-particles or cross-contaminants compromise your plastic implants or semiconductor components.

Swiss machining often leaves a cutoff burr or nib. How does XTPROTO deliver "ready-to-assemble" parts without secondary handling?

We eliminate cutoff burrs directly on the machine. By leveraging our 7- to 8-axis simultaneous dual-spindle setups, the sub-spindle synchronized grabs the component during the final cutoff phase. We then execute an automated back-working deburring, chamfering, or face-milling operation on the sub-spindle while the main spindle begins the next part. This ensures a 100% burr-free finish straight out of the machine, eliminating costly manual secondary operations.

For long, slender shafts up to 30 inches, how do you manage surface finish and prevent scratching through the guide bushing?

Long-shaft Swiss turning requires precise material pairing and synchronization. We use custom-fitted, adaptive ceramic or carbide guide bushings calibrated precisely to the ground bar stock's outer diameter. For cosmetic or high-mirror components, we utilize synchronized driven guide bushings that rotate perfectly in tandem with the headstock, completely eliminating the friction, galling, and rotational micro-scratches common in traditional stationary setups.

What are your Quality Assurance (QA) and First Article Inspection (FAI) procedures for high-volume contract runs?

Operating under AS9100D and ISO 13485, we provide full traceability. For every production launch, we generate a comprehensive AS9102 First Article Inspection Report (FAIR). During automated 24/7 contract runs, we utilize real-time, in-process gauging combined with automated tool-wear compensation systems. Critical dimensions are continuously verified using high-resolution optical comparators and automated CMMs according to strict AQL standards before shipment.

Do you have a Minimum Order Quantity (MOQ) for custom Swiss parts, and can you support scheduled Blanket Orders?

While Swiss machining setup costs naturally favor medium-to-high volumes, we do not impose a rigid MOQ; we routinely support low-volume R&D prototyping and bridge production. For scaling enterprises, we offer flexible blanket order contracts with scheduled monthly or quarterly JIT (Just-In-Time) releases. We can hold dedicated safety stock in our facility to buffer your supply chain against sudden demand spikes.
