CNC Turning FAQs
Frequently Asked Questions About CNC Turning Services
What tolerance can CNC turning achieve?
Typically ±0.01 mm for standard applications, with high-precision capabilities reaching ±0.005 mm or better for critical dimensions. Specialized Swiss-type turning can achieve ±0.0025 mm tolerances.
What is the maximum part size?
Up to Ø500 mm diameter and 1,000 mm length for standard CNC turning. For Swiss-type turning, maximum diameter is Ø32 mm. Special arrangements can be made for larger components.
What is the typical lead time?
Prototype: 3–7 working days
Production: 7–20 days depending on quantity and complexity
Express service available for urgent projects with 1–3 day turnaround
What is the difference between CNC turning and CNC milling?
CNC turning rotates the workpiece while stationary cutting tools create cylindrical parts. CNC milling uses rotating cutting tools to remove material from stationary workpieces, ideal for complex 3D shapes and features.
