Shenzhen Ruiyihang Technology makes Swiss Machined Small tight-tolerance stainless steel parts that are accurate to within ±0.01 mm in size and have a surface roughness of Ra ≤ 0.8 μm. With strict checking rules, our six Swiss-type CNC lathes can work with sizes of up to 25 mm. Since 2008, we've helped businesses around the world with engineering-driven solutions. We offer sample delivery in 3–7 days and direct technical contact with engineers who have worked in the field for 15 years or more. ISO 9001-certified, and the materials meet FDA guidelines.

You are in need of more than just a source. You need a person who knows how hard things are for you.
From the first time you ask, our tech team works directly with you. Not a middleman. There was no confusion. Just clear talks about your concept, tolerances, and the needs of the product.
This is what we've done since 2008. The people who work for us have been using Swiss turning technology for more than 12 years. They know how to work with complicated shapes and keep things the same from one production run to the next.
As soon as we make changes, you know about them. We can send you pictures and movies of your product parts as they are being made. You will be able to see exactly how we are milling your parts, which will give you peace of mind before they are shipped.

Our Swiss-type CNC lathes are specifically designed for small, high-precision work. The guide bushing support system minimizes deflection during cutting. This means better dimensional control for you.
Here's how we ensure quality at every stage:
Before Production:
During Production:
Final Inspection:
We also provide secondary operations in-house. Deburring, polishing, and passivation services ensure your Swiss Machined Small parts arrive ready for assembly.

Fast Response When Time Matters:
You'll receive quotations quickly after drawing review. Simple parts can be sampled in as little as 3 days. Typical sample lead time is 7 days.
Flexible for Your Project Stage:
Whether you're prototyping or scaling to mass production, we adapt to your volume needs. We're especially supportive of newly established companies building their supply chain.
Direct Technical Communication:
Speak directly with engineers who understand machining. We'll recommend material alternatives, suggest design modifications for better manufacturability, and help you optimize tolerances where appropriate.
Quality Issues Resolved Fast:
If you report a quality concern within the same month, we'll arrange remanufacturing within 1 week and cover shipping costs.
Global Logistics Made Simple:
We handle door-to-door delivery with optimized solutions for small-batch orders. Duties and shipping can be coordinated together for your convenience.
These are some possible uses for your product parts:
We make more than just parts. We help you solve problems in manufacturing by giving you technical advice that you can use.

Q: What size range is considered small parts in Swiss machining?
Small parts typically refer to components with diameters up to Ø25 mm, suitable for high-precision Swiss machining. Our equipment handles this range efficiently with excellent dimensional control.
Q: What industries commonly use small Swiss machined parts?
Small parts are widely used in electronics, robotics, automotive, medical devices, and industrial equipment. Anywhere precision and consistency matter, Swiss machining excels.
Q: What are the advantages of Swiss machining for small parts?
Swiss machining provides excellent stability, high precision, and consistent quality, especially for small-diameter components. The guide bushing support reduces deflection, enabling tighter tolerances than conventional turning.
Q: Can you handle high-volume production of small parts?
Yes, Swiss machines are highly efficient for producing small parts in large volumes with stable quality. Our 6 machines and experienced operators can scale production while maintaining tight tolerances.
