Precision Turning Machining — Where Accuracy Meets Efficiency
Dakings delivers high-precision CNC turning services for cylindrical parts, from micro-components to large shafts, with tight tolerances (±0.002mm) and consistent quality across industries.
Our CNC turning expertise combines precision, versatility, and efficiency to meet the most demanding part requirements.
Tight Tolerance Control
Achieve ±0.002mm tolerance on diameters and lengths, with concentricity ≤0.005mm for rotating parts (e.g., shafts, bushings) — critical for smooth operation in machinery.
All-in-One Machining
Handle threads (UN/metric), tapers, grooves, and cross-holes in a single setup via 4-axis live tooling, reducing tolerance stack-up and lead time.
Materials Expertise
Turn metals (aluminum, stainless steel, titanium) and plastics (PEEK, POM) with optimized tooling — even hard materials like 440C stainless steel (HRC 50+).
Scalable Production
24hr turnaround for prototypes (1-100 units) and automated bar feeders for high-volume runs (10k-100k+ units), balancing speed and consistency.
Industry-Specialized Teams, Precision Solutions for Your Sector

Our One-Stop Turning Machining Process
Streamlined Workflow From Design to Delivery
Design Review & DFM
Engineers analyze drawings to optimize toolpaths, fixturing, and material selection, suggesting cost-saving tweaks (e.g., simplified grooves) without compromising specs.
Material Preparation
Source certified raw materials (bars, tubes) from trusted suppliers; pre-inspect for defects to avoid machining issues.
CNC Programming & Setup
Generate precision G-code for tool changes and feeds; trial-run first part to validate dimensions before full production.
Machining & In-Process Checks
Use 3-axis/4-axis lathes for high-accuracy turning; operators perform hourly inspections (micrometers, thread gauges) to maintain consistency.
Post-Processing
Deburr edges, polish surfaces (Ra ≤0.8μm), and apply surface treatments (anodizing, plating) as specified.
Final Inspection & Delivery
Full CMM inspection for critical dimensions; package with anti-corrosion protection and deliver with quality reports.
Quality Control for Turning
Our quality control process ensures every turned part meets or exceeds your specifications.
Dimensional Inspection
Zeiss CMM for 3D measurement of diameters, lengths, and concentricity.
Thread gauges (GO/NO-GO) for thread fit; profilometers for surface finish (Ra 0.4μm–1.6μm).
Material Validation
Verify material certificates (heat treatment, composition) for metals/plastics.
Hardness testing (Rockwell/Brinell) for heat-treated parts (e.g., 4140 steel shafts).
Functional Testing
Rotational balance checks for high-speed parts (e.g., motor shafts). Assembly trials to ensure compatibility with mating components.
Traceability
Batch-specific inspection logs, first-article reports (FAI), and material certs stored for 10+ years.
Materials Supported & Surface Finishing
Materials & Finishes for Every Application needs.
Materials List & Common Finishes
1 -
Metals
Aluminum (6061, 7075) — lightweight, ideal for automotive or electronics.
Stainless Steel (304, 316, 440C) — corrosion-resistant, for medical or industrial.
Titanium (TC4) — high-strength, used in aerospace. Brass or Copper — conductive, for electrical connectors.
Plastics
POM (Acetal) — low friction, for gears/bushings. PEEK — high-heat resistance, for medical/industrial.
Specialty Materials
