When your project needs precision that can't be matched, Swiss Machined Precision delivers. We at Shenzhen Ruiyihang Technology Co., Ltd. make ultra-precise parts out of stainless steel SS316 using cutting edge Swiss-type CNC technology. We've been making small, precise parts with surface roughness as low as 0.8 μm and limits up to ±0.01 mm since 2008. Our facility has 6 specialised Swiss-type CNC lathes that are best for parts with a diameter of up to 25 mm. We serve clients from all over the world who need solid quality and quick turnaround—we can often deliver samples in 7 days and simple parts in just 3 days.

The Swiss turning method changes the way that small, complicated parts are made. In contrast to traditional grinding, this method keeps your piece of work supported near the cutting zone the whole time. This means the least amount of movement and the most steadiness.
You get parts that are accurate from one batch to the next. Your supply runs stay the same. The way you put things together runs more smoothly.
Our six Swiss-style CNC lathes are great at working with stainless steel. The spinning bar stock moves through a guide shaft as several tools work at the same time. This setup cuts down on cycle time and improves precision, which is exactly what you need for tough jobs.

Reliable After-Sales: Responsive support doesn't end at delivery. We stand behind our work with clear policies and quick action.

Q: What level of precision can Swiss machining achieve?
Swiss machining can achieve tight tolerances up to ±0.01 mm or better, especially for small, high-precision components. This makes it ideal for medical devices, aerospace fittings, and instrumentation parts.
Q: How does Swiss machining maintain such high accuracy?
Continuous support close to the cutting area minimizes deflection, ensuring stable machining and consistent dimensional accuracy. The guide bushing holds your workpiece firmly while tools cut precisely where needed.
Q: Can Swiss machining deliver consistent quality in batch production?
Yes, Swiss machines are ideal for high-volume production with excellent repeatability and minimal variation. Once we dial in your specifications, every piece matches the first. Our product excels at maintaining quality across thousands of components.
Q: What surface finish can be achieved with Swiss machining?
Surface finish can typically reach Ra 0.8 μm or finer, depending on material and cutting conditions. We also offer additional services including polishing, deburring, and passivation for enhanced finish and corrosion resistance.
