Product Description
Precision Stainless Steel Turned Components for OEM and Industrial Applications
Custom Stainless Steel CNC Turning Parts are precision-machined components engineered for industrial automation, medical devices, fluid control systems, and high-performance OEM applications.
By integrating multi-axis CNC turning with live tooling-including cross-drilling, threading, grooving, and precision milling-we manufacture complex cylindrical components directly from 2D drawings or 3D CAD models. Our advanced machining workflows ensure exceptional process repeatability, providing wholesale buyers and OEM manufacturers with stable batch-to-batch consistency for automated assembly lines.
Key Features
Excellent Corrosion Resistance & Material Selection
We machine high-quality components tailored to specific operating environments, balancing mechanical strength, corrosion resistance, and cost efficiency:
• 303 Stainless Steel: Optimized for superior machinability and high-efficiency production of precision fasteners and connectors.
• 304 Stainless Steel: The industry standard for general industrial components requiring excellent corrosion resistance and weldability.
• 316 Stainless Steel: Enhanced with molybdenum to resist chloride pitting and harsh chemical environments, ideal for marine and medical applications.
• 17-4PH Stainless Steel: A precipitation-hardening grade that delivers extreme tensile strength and hardness after heat treatment for heavy-duty mechanical parts.
Micron-Level Dimensional Consistency
Our production facility utilizes rigid machining setups and optimized cutting strategies to control thermal deformation, ensuring tight tolerances even on long shafts and thin-walled geometries:
Linear Tolerances: Standard: ±0.01 mm to ±0.05 mm
• Precision: Up to ±0.005 mm (Depending on part geometry, material grade, and inspection requirements).
• Geometric Tolerances: Exceptional concentricity, cylindricity, and runout control.
• Surface Roughness: Standard Machining: Ra 0.8–3.2 μm
• Fine Finishing: Up to Ra 0.4 μm (With secondary polishing or equivalent finishing processes).
Flexible Production Scale
Our workshop supports the entire product lifecycle, offering rapid scaling from initial prototyping to high-volume contract manufacturing. Every design undergoes a rigorous Design for Manufacturability (DFM) review prior to production to optimize machining cycles and reduce material waste.

Advanced Manufacturing Capacity
Reliable OEM supply relies on advanced hardware and systematic production management. Our machining floor is equipped with:
• Multi-tasking CNC turning centers and precision Swiss-type lathes for small-diameter, complex parts.
• In-house tooling design and fabrication to accelerate setup times for custom geometries.
• Scalable monthly capacity supporting prompt order fulfillment for global supply chains.
Comprehensive Quality Assurance
Quality control is embedded into every stage of our manufacturing execution system (MES):
Inbound Material Verification: Spectrometric analysis and PMI testing to verify stainless steel grades.
First Article Inspection (FAI): Complete dimensional sign-off before commencing bulk runs.
In-Process Quality Control (IPQC): Frequent, scheduled dimensional checks at the machine station.
Final Inspection (FQC): Full geometric verification using CMM (Coordinate Measuring Machines), optical comparators, and thread gauges.
Traceability Documentation: Standard supply of Full Dimensional Inspection Reports and Material Test Certificates (MTC) with every shipment.
Global Logistics & Protective Packaging
To preserve precision threads and micro-finishes during international transit, components are packed using tailored industrial solutions:
• Individual cell trays or protective mesh netting for high-precision surfaces.
• Anti-static and anti-moisture vacuum packaging.
• Heavy-duty export cartons reinforced with palletization and strapping for secure sea/air freight.
Frequently Asked Questions
Q: What is your typical lead time for custom parts?
A: Prototypes & Samples: Typically 3 to 7 business days depending on design complexity.
Mass Production: Generally 2 to 4 weeks, scaled according to order volume and secondary finishing requirements.
Q: Can you work from 3D CAD models if I do not have 2D drawings?
A: Yes. We accept 3D models in STEP, IGES, SolidWorks (.sldprt), or Parasolid formats. However, we recommend providing a 2D drawing (PDF) to specify critical tolerances, thread callouts, and surface finish requirements.
Q: Are your materials compliant with international environmental regulations?
A: Yes. All raw material batches are sourced from certified mills, and we provide RoHS and REACH compliance certificates upon request.
