CNC Swiss Machining: Technical & Production FAQ
What makes Swiss machining different from conventional CNC turning?
The defining feature is the sliding headstock and guide bushing. Unlike standard lathes, the material moves axially while the tool remains stationary near the support, eliminating part deflection and vibration for long, slender components.
Why is a guide bushing critical for micro-precision parts?
The guide bushing provides rigid support immediately adjacent to the cutting tool. This allows us to achieve incredibly tight tolerances of ± 0.002mm on parts with high length-to-diameter (L/D) ratios that would otherwise bend. For more details about our company and expertise, please visit our about page.
Can you handle high-volume production for complex micro-pins?
Yes. Our fleet of 20+ Star and Citizen machines utilizes automatic bar feeders for 24/7 "lights-out" manufacturing. We easily scale from rapid prototyping to mass production of 1M+ units with consistent quality.
Which materials are best for Swiss sliding headstock machining?
We excel in machining Titanium (Gr5/Gr23), Stainless Steel (316L, 17-4PH), and high-performance plastics like PEEK. We use specialized bushings to ensure scratch-free surfaces on medical and aerospace-grade materials.
How does ProtoBatch ensure "Zero Defect" quality at micro-scale?
We utilize Keyence IM Series vision systems and 50x magnification microscopes for inspection. Every shipment includes full dimensional reports and SPC data (CPK > 1.33) to guarantee absolute precision.
