CNC turning services for shafts, pins, bushings, sleeves, and other rotational components. We review the drawing, material, critical diameters, threads, finish, quantity, and inspection needs before confirming the process and quotation.
CNC turning is a subtractive machining process in which the workpiece rotates while a stationary cutting tool removes material โ the opposite of milling. A CNC turning machine automates this motion under programmed control, producing cylindrical features to the drawing requirements. Use turning for round, rotationally symmetric parts; send flat faces, pockets, and complex prismatic geometry to milling instead.
Typical parts we produce include shafts, pins, bushings, and fittings โ any component whose critical dimensions are diameters, bores, threads, or tapers rather than flat surfaces.
| Turning | Milling |
|---|---|
| Workpiece rotates, tool stays stationary | Tool rotates, workpiece stays stationary |
| Best for round parts: shafts, pins, bushings, fittings | Best for flat faces, pockets, slots, complex 3D geometry |
| Typical features: diameters, bores, shoulders, grooves, and threads | Typical features: flat faces, pockets, slots, and contoured geometry |
| Typical result: rotationally symmetric features | Typical result: prismatic parts with multiple feature types |
CNC turning is suited to parts whose key features are rotational, such as outside diameters, bores, shoulders, grooves, and threads. The workholding and operation sequence are selected from the part geometry and drawing requirements. Critical diameters, bores, threads, and datum relationships are reviewed as part of the turning plan.

CNC turning services may include external turning, facing, boring, threading, grooving, cutoff, and taper turning. Live tooling or a secondary milling operation can be considered when the part includes cross-holes, flats, or other non-rotational features.
| External turning | Outside diameters, shoulders, and profiles defined by the drawing |
|---|---|
| Facing & boring | End faces and internal bores related to the specified datums |
| Threading | External and internal thread requirements reviewed against the drawing |
| Grooving & cutoff | Grooves and parting features planned to the specified geometry |
| Taper turning | Tapers and mating features machined to the part drawing |
| Live tooling | Cross-holes, flats, or tapped features where machine configuration permits |
| Secondary operations | Part transfer or additional milling is considered when required by the geometry |
| Production planning | Quantity, stock form, and repeat requirements are reviewed for each inquiry |
| Part envelope | Confirmed against available equipment and workholding for the part |
|---|---|
| Machining length | Reviewed from part length, support needs, and setup plan |
| Tolerances | Reviewed against each feature and confirmed during quotation |
| Surface finish | Specified on the drawing and reviewed with the material and operation |
| Material form | Stock form and material are confirmed for the requested part |
The turning setup is selected to suit the part geometry and required operations. A turning center may combine turning with additional features where its configuration supports them; feasibility is confirmed during drawing review.
| Turning center | Used for rotational features, with additional operations considered where available configuration allows. |
|---|---|
| Workholding | Chuck, collet, or other workholding is chosen to support the part and its datums. |
| Secondary milling | Cross-features are planned as live-tool operations or separate milling based on the part. |

Turning produces cylindrical parts by rotating the workpiece against a stationary cutting tool. Milling produces prismatic parts by rotating cutting tools against a stationary workpiece. Many parts require both operations.
Thread requirements are reviewed from the drawing, including thread type, dimensions, and any inspection criteria. Feasibility is confirmed during quotation.
Provide a 2D drawing or 3D model with the material, quantity, critical diameters, threads, finish, and inspection requirements so the turning process can be reviewed.
