Machining + Turning axis parts
✔ High Precision – Achieves tolerances as tight as ±0.005 in (±0.127 mm). ✔ Excellent Surface Finish – Typically 125–250 µin (3.2–6.3 μm Ra) without additional machining.
Advantages of CNC Turning Milling Axis Parts
1. High Precision
CNC turning milling axis parts can achieve extremely tight tolerances, up to ±0.01mm, ensuring consistency and accuracy in every component.
2. Efficiency
CNC lathes enable efficient mass production, making them ideal for batch manufacturing. The automated process reduces human error and increases productivity.
3. Versatility
These parts can be made from a wide range of materials, including metals like aluminum, steel, and titanium, as well as plastics and composites, allowing for diverse applications.
CNC Turning Milling Axis Parts Process
1. Turning
The primary process involves a cutting tool removing material from a rotating workpiece to create cylindrical or conical shapes.
2. Milling
For complex geometries, milling is combined with turning in multi-axis CNC machines, enabling the production of intricate designs in a single setup.
3. Multi-Axis Turning
This advanced technique allows for simultaneous machining on multiple axes, enhancing precision and reducing the need for multiple setups.
Applications of CNC Turning Milling Axis Parts
1. Shafts & Rods
Used in motors and axles, these parts require high straightness and surface finish.
2. Bushings & Bearings
Ideal for applications requiring tight internal and external diameter tolerances, such as sleeve bearings and spacers.
3. Flanges & Fittings
Components like pipe connectors and hydraulic fittings benefit from precise threading and sealing surfaces.
4. Screws & Fasteners
Bolts, nuts, and threaded inserts are manufactured with exacting thread specifications and knurling.
5. Complex Profiles
Parts like camshafts and turbine blades, which require multi-axis turning and milling, are also produced.

FAQs
How to reduce vibration (chatter) in CNC turning milling?
Use sharp tools with proper rake angles, optimize RPM and feed rates, and employ dampened tool holders or steady rests for long parts.
What' s the best surface finish for CNC turned milled parts?
Roughing: Ra 3.2–6.3 μm (125–250 μin). Finishing: Ra 0.4–1.6 μm (16–63 μin). Superfinishing: Ra <0.2 μm (8 μin) with lapping or grinding post-turn.
How to hold thin-walled parts without deformation?
Use collet chucks for even clamping, machine in multiple passes to relieve stress, and consider magnetic or vacuum chucks for delicate work.
What causes poor surface finish in CNC turning milling?
Tool wear, incorrect speeds/feeds, and improper coolant use can all contribute to poor surface inish.
