Flexible Multi-Axis Turning for Larger Diameter Parts
Zhuocheng provides CNC turning for larger diameter precision components that fall outside the Swiss-type range. With multi-axis CNC lathes, we produce shafts, flanges, rings, housings and custom turned parts to customer drawings — supporting prototype through mass production.

Why CNC Turning?
Understanding when and why to choose cnc turning for your parts.
-
Flexible Diameter Range
CNC turning handles larger diameters that Swiss-type machines cannot — from Ø10 mm up to Ø200 mm.
-
Multi-Axis Capability
3-, 4- and 5-axis CNC lathes enable complex profiles, tapers and multi-diameter geometries in one setup.
-
Prototype to Mass Production
Bar feed and chuck jaw capacity support everything from single prototypes to high-volume production runs.

CNC Turning in Practice
An anonymized example showing how this process solves a real manufacturing challenge.
Stainless Steel Sensor Housing
- Application
- Automotive sensor assemblies
- Material
- Stainless steel 304
- Challenge
- Multi-diameter housing with internal groove, threaded end and tight concentricity between OD and ID.
- Process
- CNC turning with live tooling for internal groove and threading in one setup.
- Result
- Stable production with consistent concentricity and thread quality across lots.

Frequently Asked Questions
What diameter range can you turn?
Typical turning diameter is Ø10–200 mm. For diameters outside this range, please send the drawing for review.
Can you combine turning and milling on the same part?
Yes. Our turn-mill centers can perform turning, milling, drilling and tapping in one setup.
What is the typical tolerance?
Typical tolerance is ±0.01 mm, drawing-dependent. Tighter tolerances may be achievable depending on geometry and material.
Do you support mass production?
Yes. We support prototype, pilot batch and mass production with stable setups and process control.
What materials can you machine?
Stainless steel, carbon/alloy steel, aluminum, brass, bronze and titanium. Other materials can be reviewed.
