Product Description
CNC Stainless Steel Turned Parts are precision-machined components produced through advanced CNC turning processes to achieve accurate dimensions, reliable mechanical performance, and consistent quality for high-requirement industrial applications.
Stainless steel is widely selected for turned components due to its excellent corrosion resistance, high tensile strength, and stable performance in demanding environments. Depending on your specific application, we offer a wide range of stainless steel grades to perfectly balance machinability, corrosion resistance, hardness, and cost.
Our CNC turning capability supports customized production of stainless steel shafts, bushings, pins, connectors, fittings, threaded components, and other complex mechanical parts. We manufacture strictly according to customer drawings, 3D models, samples, and technical specifications, seamlessly supporting both rapid prototype development and high-volume repeat production.
CNC Stainless Steel Turning Capability
Stainless steel machining requires precision control over cutting parameters, tooling life, and process stability because different grades exhibit distinct machining characteristics. Proper material selection and rigid machining control directly influence surface finish, dimensional accuracy, and the long-term performance of the components.
Our Comprehensive Manufacturing Services Include:
• Precision CNC Turning & Lathe Machining
• Multi-Axis Milling Secondary Operations (for complex geometries)
• High-Precision Shaft Machining
• Deep Hole Drilling & Precision Boring
• Internal & External Thread Machining (Standard & Custom pitches)
• Advanced Surface Finishing & Treatment
Product Features & Technical Advantages
High-Precision Dimensions for Perfect Assembly
Dimensional consistency is critical for CNC turned parts used in tight-tolerance mechanical assemblies. Even minor variations in shaft diameter, hole size, or thread dimensions can lead to assembly failure.
• Standard Machining Tolerance: Generally controlled within ±0.05 mm.
• Critical Tolerances: Can achieve up to ±0.01 mm (depending on part geometry, material grade, and specific inspection setup).
• Batch Consistency: During production, key dimensions are continuously monitored using precision instruments to ensure zero variance between batches, providing reliable stability for your long-term repeat orders.
Certification & Premium Stainless Steel Material Options
We stock a diverse inventory of certified materials to match your specific operating environment, load requirements, and corrosion exposure:
• 304 Stainless Steel (SUS304 / 1.4301)
A versatile, general-purpose stainless steel offering excellent corrosion resistance and mechanical performance. Ideal for industrial equipment parts and general mechanical assemblies.
• 316 Stainless Steel (SUS316 / 1.4401)
Contains molybdenum for superior resistance to pitting and corrosion, especially in environments exposed to moisture, chemicals, or marine conditions.
• 303 Stainless Steel (SUS303 / 1.4305)
Specifically sulfur-alloyed for enhanced machinability, making it the premier choice for complex, precision turned components requiring high production efficiency.
• 17-4PH Stainless Steel (630 / 1.4542)
A chromium-copper precipitation-hardening stainless steel that delivers exceptionally high strength and hardness after heat treatment, perfect for heavy-duty aerospace and industrial components.

Surface Treatment Options
To enhance both performance and longevity, we provide professional surface finishing tailored to your industry standards:
Passivation (Chemical Cleaning): A critical treatment that removes free iron and surface contaminants, forming a transparent chromium oxide protective layer to dramatically boost corrosion resistance. (Performed according to ASTM standards upon request).
Precision Polishing: Reduces surface roughness (low Ra value) and improves appearance for fluid-handling components or cleanroom applications.
Brushing & Sand Blasting: Delivers uniform, non-reflective matte or textured finishes for functional aesthetics.
