High-Volume CNC Turning Services
CNC Turned Parts for Batch Production
Laidnuo Technology supplies custom CNC turned parts, high-precision turned components, and complex rotary shafts for batch and high-volume production. Supported by a manufacturing fleet of 100+ advanced production devices, our automated bar-fed turning lines ensure exceptional dimensional stability, strict micrometer-level concentricity control, and complete repeatability for continuous orders.
From raw metal stock through multi-axis turning, specialized surface treatments, and final validation—every part moves through production without ever leaving our facility.
Guaranteed Accuracy: We consistently hold stable precision tolerances within ±0.005 mm for critical rotary features such as sleeves, bearings, and nuts.
Traceable Quality: Every batch ships fully backed by comprehensive quality documentation, including raw material certificates and official dimensional inspection reports to meet international industry standards.
CNC Turning Manufacturing Capabilities
Our standard CNC turning tolerances strictly adhere to ISO 2768-m for metals. For critical dimensions requiring higher precision than standard commercial limits, our multi-axis turning cells can consistently hold tight tolerances down to ±0.005 mm. Please clearly specify these high-precision requirements on your 2D engineering drawings or reach out to our technical team for an immediate evaluation.
| Design Feature | General Recommendation | Laidnuo Capability | DFM Optimization Tips |
| Optimal Diameter | 0.3 mm – 300 mm | Supported by our 100+ advanced production devices, specializing in precision chuck turning up to Ø300mm and automated bar-fed mass production. | Designing the outer diameter of your part to match standard metal bar stock sizes significantly reduces rough turning cycle times and material waste. |
| L/D Ratio (Length/Diameter) | Ratio <= 3:1 or 4:1 | Powered by high-rigidity multi-axis spindles, effortlessly cutting high-hardness metals (stainless steel, carbon steel, titanium alloy). | For parts with an L/D ratio exceeding 4:1, designing an upfront step or contact face helps prevent tooling deflection and vibration during high-speed cutting. |
| Tolerance & Roundness | ±0.005 mm | Our metrology lab utilizes high-precision CMMs and optical measuring instruments to control concentricity and runout at the micrometer level. | For critical cylindrical surfaces involved in fluid sealing, bearing fits, or alignment sleeves, please clearly specify concentricity requirements on your drawings. |
| Threading & Surface Finish | Standard Metric / Imperial | Delivers ultra-smooth turned threads, with comprehensive in-house post-treatments including anodizing, sandblasting, electroplating, and powder coating. | Always specify standard thread sizes where possible and design a thread relief undercut at the end to maximize mass-production efficiency. |

Got Questions? We’ve Got Answers!
Are you a trade company or a factory?
We are a direct manufacturer.
Our factory is equipped with more than 100 high-end production devices, including complete CNC machining and sheet metal production lines. Fully equipped and stable operating equipment ensures consistent quality, sufficient production capacity, and shorter lead times, enabling efficient and fast delivery to meet customer requirements.
Do you offer material certificates and quality inspection reports?
Yes. We provide comprehensive quality documentation tailored to your project requirements. As an IATF 16949:2016 and ISO 9001:2015 certified manufacturer, we can supply Material Mill Certificates (COA/MTC), RoHS/REACH compliance reports (verified by our in-house RoHS analyzers), First Article Inspection (FAI) reports, and PPAP level documents upon request.
Are my CAD design files safe with you? Can you sign an NDA?
Yes, 100%. Your intellectual property is our highest priority. We strictly safeguard your designs through a multi-layered security protocol:
1. Legal Protection: We gladly sign a formal Non-Disclosure Agreement (NDA) before you share any drawings or project data.
2.On-Site Security: Our manufacturing facilities operate under strict physical access controls, and all internal teams are bound by rigorous confidentiality agreements. Your designs never leave our secure network.
Do you have a Minimum Order Quantity (MOQ)?
We offer ultimate flexibility with NO strict MOQ for prototypes and low-volume parts to support your engineering validation. For mass production, we recommend a batch of 500+ parts to ensure the best per-part cost-efficiency and long-term batch-to-batch consistency.
How fast can I get a quote and when will my parts be delivered?
We provide detailed quotes and Free DFM analysis within 24 hours. For rapid prototypes, parts can be shipped in as fast as 3-5 days. For low-to-medium volume production and injection molding, the standard lead time is typically 1-3 weeks depending on the part complexity and volume.
