Precision CNC Turned Parts
CNC turning centers (2-axis / 3-axis / multi-axis) use carbide tools and high spindle speeds for precision machining. Threading, knurling, polishing, and cleaning ensure final quality.
2.Our Capabilities
We provide stainless steel CNC turning, including passivation and finishing. With 15 CNC lathes and turning-milling centers, we ensure stable production.
3.Quality Control
Incoming spectrometer inspection
In-process checks with calipers and micrometers
Final CMM and surface testing
ISO 9001 compliant system
Precision CNC Turned Parts – Engineered for Accuracy & Consistency
Precision CNC Turned Parts are very important when your project needs very close standards and quality that can be repeated. Since 2008, Shenzhen Ruiyihang Technology Co., Ltd. has been making custom-turned parts for businesses around the world with engineering-driven accuracy. We can control tolerances as small as ±0.02 mm, finish surfaces down to Ra 0.8 μm, and turn around samples quickly—in as little as 3 days. With more than 15 CNC lathes and a team with an average of 15+ years of experience, we can help with everything from making a pilot to mass production. We offer direct contact between engineers and follow ISO 9001 standards.
What Makes Our CNC Turned Parts Different?
Direct Engineering Support
There won't be anyone between you and our engineers. We look over your ideas, tell you what we think would be better, and make sure they are simple to build. This makes mistakes less likely and speeds up your project a lot.
Advanced Turning Capabilities
At our place, we have 2-axis, 3-axis, and multi-axis turning centers with diamond tools. Through sewing, knurling, and very detailed curves, we work with forms that are hard to understand. You can get what you need from us whether it's metal, aluminium, brass, stainless steel, or industrial plastics.
Quality You Can Rely On
Each batch goes through a strict inspection:
- Spectrometer testing coming in for material confirmation
- In-process checks of dimensions using micrometres that have been measured
- Last CMM readings and tests for surface roughness
For important uses, 100% inspection is possible
Manufacturing Process
The way we make our Precision CNC Turned Parts is controlled:
Step 1: Check the material. A spectrometer study proves the alloy's make-up before the cutting process starts.
Stage 2: CNC Turning: High-speed mills and precision tools remove material with micron accuracy.
Step 3: Perform any requested threading, knurling, passivation, or finishing.
Step 4: measure, test, and inspect the surface to determine quality.
Step 5: Safely ship and package. Door-to-door international delivery.

FAQ
Q: What level of exactness can be accomplished in CNC turning?
We ordinarily accomplish ±0.02 mm, with basic highlights up to ±0.01 mm or more tightly depending on portion geometry and material.
Q: What surface wrap up can be accomplished after CNC turning?
Standard surface wrap up is Ra 1.6 μm, whereas accuracy turning can reach Ra 0.8 μm or better with optimized cutting conditions.
Q: Can you guarantee concentricity and roundness for turned parts?
Yes, we keep up strict control over machining parameters to guarantee tall concentricity, roundness, and dimensional consistency.
Q: Do you bolster small-batch or model orders?
Absolutely. We specialize in adaptable production—from single models to thousands of units.
Q: Which record designs do you accept?
We acknowledge 2D drawings (PDF, DWG, DXF) and 3D models (STEP, IGES, STP, Parasolid).
