CNC Turning
CNC turning produces parts by turning rod material and feeding a cutting tool into it, with the cutter fed at a variety of angles and many tool shapes available.
On a lathe the material to be cut rotates while a cutter is fed into the rotating workpiece. This gives versatility and accuracy on round parts, and it combines turning, facing, drilling, boring, threading and tapping into a single cycle.

Turning Operations We Run
- Turning — the workpiece rotates while a single point tool removes material from the side, producing steps and chamfers.
- Facing — a thin layer is removed to create a smooth end surface.
- Drilling — a drill cuts a hole along the axis of the workpiece.
- Boring — a boring tool enlarges drilled holes or adds internal steps and chamfers.
- Threading — a single point tool forms threads on the outer surface.
- Tapping — a tap cuts internal threads in the workpiece.
CNC Turning FAQ
What diameter bar can you turn?
Round bar from 1 mm to 300 mm diameter. Parts far outside that range may not suit turning, so send the drawing if yours sits at either extreme.
What surface finish can you reach?
Up to Ra 0.4 straight from the lathe. Where a smoother surface is required we follow with grinding or polishing.
Can a turned part have flats or cross holes?
Yes. Those features are machined on the milling side, and where concentricity matters we plan the sequence so the turned datum is preserved.
Which materials turn most economically?
Free machining grades such as 12L14 steel and SUS303 stainless cut faster and cost less per part than 304 or titanium.
