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
Swiss CNC machining is a precision manufacturing process originally developed for the Swiss watch industry and widely used today to produce small, complex, and high-precision parts. Unlike conventional turning, Swiss-type machines use a guide bushing and sliding headstock to support the workpiece close to the cutting tool, reducing deflection and improving accuracy. Our Swiss CNC machining services combine turning, milling, drilling, and slotting in one setup to efficiently produce precision components from metals and engineering plastics for a wide range of industries.
Swiss CNC Machining Capabilities
Our Swiss CNC machining capabilities support the production of complex, small-diameter precision parts with multi-axis equipment and advanced automation. Swiss-type lathes can perform cut-off, form turning, internal and external threading, knurling, drilling, and milling in a single setup, reducing secondary operations and improving efficiency. Our machines support up to 8 axes and 32 tools, with maximum part diameters up to 1.25 in (31.75 mm) and tolerances as tight as ±0.0005 in. We also enable unattended bar-fed production for long-running jobs, delivering consistent quality and cost-effective manufacturing.
We machine a wide range of metals and high-performance alloys, including aluminum, brass, copper, alloy steels, stainless steel, titanium, and nickel-based alloys such as Inconel. Our Swiss machining services support demanding industries including aerospace, medical, semiconductor, and industrial manufacturing, delivering reliable, high-precision components for both prototype and production applications.

Our Expert Team
Xtproto’s team brings over 20 years of experience in Swiss CNC machining, delivering complex, high-precision parts for aerospace, medical, automotive, and electronics industries. Working directly with clients, we provide transparent communication, full-service support, and advanced multi-axis machining to ensure every part meets tight tolerances and superior quality.
Tolerances & Precision in Swiss CNC Machining
Swiss CNC machining delivers tight, reliable tolerances that are difficult to achieve with conventional turning. Our Swisstype lathes routinely achieve precision tolerances down to ±0.0001 in (±0.0025 mm), with many applications held at ±0.0002–±0.0005 in depending on geometry and material. The combination of guide bushing support, multiaxis tool motion, and advanced CNC control ensures repeatable dimensional accuracy and consistent quality across small and complex parts. Whether it’s critical fits, thin walls, or micro features, our Swiss machining process provides the precision your design demands, supporting industries where exacting tolerances are essential.
Swiss-Type CNC Lathes
Our Swiss machining department is equipped with advanced Star and Tornos Swiss-type CNC automatic lathes, designed for high-precision small-part production. These machines support multi-axis machining (up to 7+ axes) and can perform multiple operations in a single setup, including turning, drilling, milling, broaching, knurling, threading, tapping, and cut-off. Our Swiss lathes can machine parts with diameters from 0.012 in to 0.814 in and lengths up to 30 in, with tolerances as tight as ±0.0001 in. Compatible with a wide range of materials—including stainless steel, aluminum, Kovar, and nickel-based alloys such as Inconel—these machines deliver consistent precision and efficiency for complex, small-diameter components.

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.
Advantage Of CNC Machining
- Reduced Cycle Time
- Superior Surface Finish
- High Production Efficiency
- Tight Tolerances & Accuracy
- Cost-Effective Small-Batch Production
- Complex Geometry Capability
Multi-axis Swiss machines perform multiple operations in one setup, cutting down machining and waiting times while lowering overall costs.
Parts come off the machine with consistent, high-quality finishes without additional grinding or polishing.
Automated operation and multiple spindles/tools allow continuous machining with minimal operator intervention.
Modern CNC Swiss machines, like Citizen L32x and Nexturn models, achieve ultra-precise tolerances for demanding applications.
Swiss machining efficiently handles both prototypes and short runs, reducing material waste and overall expenses.
Drilling, milling, turning, threading, and grooving can all be performed in a single setup, making it perfect for intricate parts.
