What are CNC turned components and what tolerances can be achieved?
CNC turned components are high-precision rotational parts manufactured by rotating raw bar stock against cutting tools on multi-axis CNC lathes. Fedele Autocore achieves tight tolerances down to ±0.01mm (±0.0004 in) across diameters from 3mm to 500mm in stainless steel, aluminum, brass, alloy steels, and titanium, verified by 100% CMM inspection under ISO 9001:2015 quality control.
Key Advantages & Benefits
Engineered for precision and production efficiency.
Precision Dimensional Accuracy
Achieve tolerances to ±0.01mm with rigid machine construction, precision ball screws, and advanced CNC control systems ensuring dimensional accuracy essential for automotive, aerospace, and precision engineering applications requiring tight geometric tolerances.
Complex Geometry Capability
Multi-axis CNC lathes with live tooling, C-axis positioning, and Y-axis capability produce complex contoured surfaces, off-center holes, cross-drilling, milling flats, and intricate features in single setup eliminating secondary operations and maintaining tight tolerances.
Superior Surface Finish
Sharp carbide inserts, optimized cutting parameters, and rigid tooling achieve surface finishes to Ra 0.8µm on turned surfaces, reducing or eliminating secondary grinding and polishing operations saving time and cost.
High-Volume Production
Automatic bar feeders, multi-spindle capability, and optimized cycle times enable production volumes exceeding 500,000 pieces annually with consistent quality. Statistical process control ensures every part meets specifications throughout extended production runs.
Material Versatility
Process diverse materials from free-machining steel and aluminum to difficult-to-machine stainless steel, titanium, Inconel, and hardened alloys with specialized tooling, optimized cutting parameters, and coolant systems designed for each material family.
Cost-Effective Manufacturing
Single-setup manufacturing with live tooling eliminates secondary operations, reduces handling, and minimizes scrap. Near-net-shape turning reduces material waste. Automated production enables competitive pricing for both prototype and high-volume runs.
Comprehensive CNC Turning Services
Complete range of precision turning operations.
Precision OD/ID Turning

- Metric & imperial threads
- ACME & custom profiles
- Fasteners & connectors
Live Tooling Milling
Powered rotary tools and Y-axis positioning enable milling, drilling, cross-drilling, and slot cutting while part rotates in spindle. Eliminates secondary milling operations, completes complex features in single setup, and maintains tight positional tolerances reducing total manufacturing time.
- Y-axis positioning
- Powered live tooling
- Cross-drilling & slots
- Complex features single setup
Grooving & Parting Operations
Precision grooving inserts create O-ring grooves, snap ring grooves, undercuts, and relief grooves with controlled width and depth. Parting-off operations complete parts with minimal burr requiring no secondary finishing. Essential for sealing surfaces and mechanical assemblies.
- O-ring & snap ring grooves
- Precision width & depth control
- Minimal burr parting-off
- Sealing & mechanical assemblies
Sub-Spindle Operations
Sub-spindle receives part from main spindle for backside operations including facing, drilling, threading, and cut-off. Completes both ends of component in single setup, eliminates part flipping, maintains alignment for concentricity-critical components, and reduces total cycle time.
- Backside operations
- Main to sub-spindle transfer
- Both ends single setup
- Complete part manufacturing
High-Volume Bar Feeding
Automatic bar feeders handle stock from 10mm to 80mm diameter enabling lights-out manufacturing. Bar stock feeds continuously as each part completes, eliminating manual loading. Remnant minimization reduces material waste. Enables high-volume production with minimal operator intervention achieving 500,000+ pieces annually.
