The Advantages of CNC Metal Turning
CNC metal turning has many benefits over other manufacturing methods:
- Perfect Roundness: Ideal for shafts, pins, and cylindrical parts
- Excellent Surface Finish: Reduces need for secondary operations
- High Precision: Meets the strictest requirements of ASME B5.57 standards
- Material Efficiency: Minimal waste compared to other processes
- Consistency: Every part is identical to the print
Our custom CNC turning services can add special features like:
- Internal and external threads
- Grooves and undercuts
- Tapered surfaces
- Holes and bores
- Knurled sections
Why Material Matters in CNC Metal Turning
The material you choose affects many aspects of the turning process:
- Aluminum: Fast machining, excellent surface finish, lightweight
- Stainless Steel: Corrosion resistant, but requires slower cutting speeds
- Titanium: Exceptional strength-to-weight ratio, but challenging to machine
- Brass: Excellent machinability, good for electrical components
- Inconel®: Outstanding heat resistance, ideal for aerospace
Our experts can help you select the perfect material for your application based on:
- Strength requirements
- Weight considerations
- Operating environment (temperature, chemicals, etc.)
- Cost constraints
- Aesthetic needs
Advanced CNC Turning Capabilities
For complex parts, we offer advanced capabilities like:
- Multi-axis turning with live tooling for milling features
- C-axis and Y-axis machining for off-center features
- Swiss turning for long, slender parts with tight tolerances
- Hard turning for already-hardened materials
- Simultaneous operations for faster production
These advanced techniques allow us to produce complex parts in a single setup, reducing lead time and improving accuracy.
Quality Assurance
Quality is built into every step of our process:
- Material verification ensures you get exactly what you specified
- In-process inspection catches any issues before they become problems
- Final dimensional inspection with precision measuring equipment
- Surface finish verification confirms the right appearance and feel
- Documentation provides traceability for all parts
Our commitment to quality follows ASME B5.57 standards and is backed by our ISO certification.

Frequently Asked Question
In turning, the workpiece rotates while the cutting tool stays mostly still. In milling, the tool rotates and moves around the stationary workpiece.
Yes! We can machine materials up to 65 HRC using special carbide tooling and the right techniques.
Absolutely! Our team can help optimize your design for manufacturing, potentially saving you money and improving part quality.
We regularly hold tolerances as tight as ±0.0002″ (0.005mm) on diameters.
We accept orders of any size, from single prototypes to production runs of thousands.
