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.
Swiss CNC Machining Service
Our high-precision Swiss CNC machining services leverage advanced sliding headstock technology and integrated guide bushings to deliver unparalleled stability for complex, small-diameter components. By supporting the workpiece immediately adjacent to the cutting tool, our multi-axis Swiss-type lathes virtually eliminate deflection and vibration, allowing for the achievement of ultra-tight tolerances (up to 0.005 mm) and superior surface finishes on parts with high aspect ratios. This “done-in-one” manufacturing approach seamlessly integrates turning, milling, cross-drilling, and slotting into a single automated setup, significantly reducing lead times and ensuring absolute part-to-part consistency. We specialize in processing a diverse range of materials—from medical-grade titanium and 17-4 PH stainless steel to high-performance engineering plastics like PEEK—providing the aerospace, medical, and electronics industries with a scalable, cost-effective solution for intricate geometries that conventional CNC turning cannot achieve.
Precision Manufacturing Facility
At XTPROTO, our state-of-the-art CNC facility spans 160,000 sq. ft of climate-controlled space, equipped with over 200 high-precision machining centers, including multi-axis Swiss, 5-axis, and standard CNC lathes and mills. We combine advanced automation, robotics, and bar-fed Swiss-type lathes to streamline production, reduce secondary operations, and maintain consistent part quality. Every component is produced under strict ISO 9001:2015, AS9100D, and ISO 13485:2016 quality standards, with full ITAR compliance, ensuring aerospace, medical, and industrial parts meet exacting tolerances. Our experienced team leverages cutting-edge technology to perform multi-axis machining, turning, milling, and finishing operations in a single setup, delivering high-precision, cost-effective solutions from prototypes to high-volume production.


Swiss CNC Machining Capabilities
Our high-precision Swiss CNC machining services are engineered to solve the most difficult manufacturing challenges: eliminating part deflection in high-aspect-ratio components and reducing the high costs of multi-stage processing. By utilizing advanced 8-axis Swiss-type lathes equipped with up to 32 tools and automated bar-feeders, we integrate cut-off, form turning, complex threading, and multi-surface milling into a single, unattended setup. This “one-and-done” capability enables us to produce intricate geometries with diameters up to 1.25 in (31.75 mm) and ultra-tight tolerances of ±0.0005 in, maintaining absolute stability where conventional turning fails. Whether processing standard brass and aluminum or challenging high-performance alloys like Titanium, 17-4 PH Stainless, and Inconel, our process delivers repeatable, aerospace-grade quality and significantly reduced lead times. The result is a highly scalable, cost-effective production flow that empowers the medical, semiconductor, and defense sectors with precision-perfect components from initial prototype through high-volume production.

What Is Swiss Machining?
Swiss machining, also known as Swiss-type turning or Swiss screw machining, is a high-precision CNC machining process designed for producing small, complex, and ultra-precise parts. The process uses a sliding guide bushing to support the workpiece close to the cutting tool, allowing multiple operations—turning, milling, drilling, threading—in a single setup. Originally developed for the Swiss watch industry, Swiss machining now serves aerospace, automotive, defense, medical devices, electronics, and micro-component applications, delivering micron-level accuracy, superior surface finish, and consistent quality. Its ability to machine miniature, slender, and intricate components efficiently makes it ideal for modern, high-performance designs where precision and reliability are critical.
