CNC Turning

Precision lathe turning for shafts, bushings, and cylindrical parts — from Ø2 mm to Ø350 mm, all materials.

Overview

What is CNC Turning?

CNC turning uses a lathe where the workpiece rotates at high speed while a precisely controlled cutting tool removes material. The result is parts with near-perfect cylindrical geometry — shafts, pins, bushings, bearings, and threaded components that require concentricity and surface finish achievable only through precision turning.

Modern CNC lathes with live tooling go further, adding milling, drilling, and tapping capabilities to the lathe platform — enabling complex turned parts with off-centre features all in one setup. Our mill-turn centres combine 5-axis milling with turning for maximum complexity and minimum lead time.

How It Works

Our Turning Process

01

Material Selection

Bar stock, billets, or forgings selected and certified to your specification.

02

CAM Programming

Turning toolpaths programmed with Mastercam or Fusion 360 for optimal cycle times.

03

First-Off Setup

Tool offsets, datum setting, and first-article CMM inspection before production runs.

04

Production Run

Automated bar-fed turning with statistical process control for consistent results.

05

Secondary Ops

Grinding, keyway cutting, coating, or threading as required by your drawing.

06

Final Inspection

Full dimensional report, surface finish check, and material certs included.
