Product Description
CNC Metal Turned Parts are precision-machined components manufactured on CNC turning centers by rotating metal bars or tubes while cutting tools accurately remove material to create cylindrical, threaded, and rotationally symmetrical features. These components are widely used in automotive, industrial automation, fluid control, electronics, medical equipment, agricultural machinery, and robotics where dimensional accuracy, repeatability, and reliable assembly are critical.
As an ISO 9001:2008 certified OEM machining manufacturer, we produce custom CNC turned parts strictly according to customer drawings, CAD files, or technical specifications rather than offering standard catalog products. Whether your project involves precision shafts, bushings, threaded fittings, spacers, valve components, connectors, pins, or custom housings, every machining process is planned to meet your required dimensional accuracy, functional performance, and production consistency.
Our manufacturing approach focuses on preventative, stable process control instead of relying solely on final inspection. Thorough engineering review, optimized machining parameters, real-time in-process inspection, and calibrated measuring equipment work together to ensure consistent quality from rapid prototype development to high-volume production.
Product Features
High Precision for Critical Dimensions
Dimensional accuracy directly affects product assembly performance, reliability, and service life. Our standard machining tolerances are maintained at ±0.05 mm, while critical features can be controlled to ±0.01 mm depending on material properties, part geometry, machining conditions, and customer inspection requirements.
Accuracy is achieved through rigid CNC turning equipment, optimized cutting parameters, scheduled tool replacement management, and a strict First-Article Inspection (FAI) combined with in-process inspections.
Consistent Surface Finish
Surface quality influences sealing performance, friction, wear resistance, and product appearance. Under normal machining conditions, surface roughness can reach Ra 0.8–1.6 μm after precision turning, with finer finishes available upon request.
Stable spindle speed, rigid workholding, appropriate cutting tools, and optimized machining parameters help minimize vibration and tool marks, resulting in a more uniform surface across all production batches.
Wide Range of Machinable Materials
Different industries require different mechanical, thermal, and environmental properties. We machine a wide selection of materials, including:
• Stainless Steel: 303, 304, 316, 316L, 420, 430
• Carbon Steel & Alloy Steel: 12L14, 1018, 1045, 4140, 8620
• Aluminum Alloys: 6061-T6, 6063, 7075-T6, 2024
Copper & Brass: C36000, C26000, Pure Copper
Titanium: Gr2, Gr5 (Ti-6Al-4V)
Engineering Plastics: POM (Acetal), Nylon, PTFE (Teflon), PEEK
Material recommendations can be provided based on your requirements for strength, corrosion resistance, weight, machinability, conductivity, or operating environment.
Multi-Process Machining Capability
Many precision components require more than simple turning. By utilizing advanced CNC Live-Tooling Turning Centers and Mill-Turn machines, secondary machining operations are seamlessly integrated into a single setup:
• Internal and external threading
• Cross drilling & Deep-hole drilling
• Grooving & Knurling
• Boring & Tapping
• Milling flats, slots, and hexes
• Precision chamfering & Deburring
Completing multiple operations in fewer setups significantly improves positional accuracy, reduces handling errors, and shortens manufacturing lead times.
Stable Batch-to-Batch Consistency
For wholesale buyers and global OEM manufacturers, production consistency across shipments is paramount.
Standardized machining procedures (SOPs), documented process parameters, tool life tracking, fixture control, and routine in-process quality verification help maintain identical dimensions and appearance throughout repeated production runs, eliminating assembly variation at your assembly line.

Surface Finish Options
The appropriate surface treatment is selected according to the product's working environment and functional requirements.
Anodizing: Improves corrosion resistance, wear resistance, and surface hardness for aluminum components while offering aesthetic color options.
Passivation: Enhances the natural corrosion resistance of stainless steel by removing surface iron contaminants without affecting dimensional accuracy.
Zinc Plating: Provides economical, sacrificial corrosion protection for carbon steel parts.
Nickel & Chrome Plating: Significantly improves wear resistance, hardness, and reduces friction while providing a uniform, mirror-like appearance.
Black Oxide: Reduces light reflection, adds mild corrosion resistance, and maintains precise dimensional limits.
Electropolishing: Removes microscopic surface irregularities to achieve a smoother, burr-free finish suitable for medical, food-grade, or hygienic applications.
Typical Applications
Precision CNC metal turned parts are trusted in a wide range of global industrial equipment where reliable dimensional control is required:
Automotive Industry: Transmission systems, brake assemblies, engine components, fluid sensors, steering systems, and heavy-duty precision fittings.
