CNC Turning vs Swiss CNC Machining

Help buyers choose the right process before quotation.

Use CNC Turning When

Parts are short or medium length

Diameter is medium or larger

Features are mainly OD, ID, thread, groove

Shafts, bushings, sleeves, spacers

Lower setup complexity

Use Swiss CNC When

Parts are long and slender

Diameter is small, usually 0.5–32 mm

Parts require high concentricity and repeatability

Micro shafts, pins, terminals, small connectors

Better for repeat production of small precision parts

Engineering Review for CNC Turned Parts

Before quotation, our engineers review OD/ID dimensions, concentricity, thread standard, groove geometry, surface finish, material selection and inspection method.

OD / ID Fit

Confirm mating dimensions and bearing or sleeve fit.

Thread Standard

Check metric, UNC/UNF, BSP or custom threads.

Surface Finish

Confirm functional and cosmetic surfaces.

Grooves & Undercuts

Check tool access and feature width.

Concentricity

Review geometry, setup method and inspection requirement.

CNC Turning Equipment and Process Control

Our CNC turning equipment supports OD/ID machining, threading, boring, grooving and repeat production for precision round parts.

Setup Review

Confirm chucking, datum and tool access.

Toolpath Control

Support stable finish and dimensional accuracy.

Thread Control

Internal and external thread inspection.

Batch Consistency

Repeatable turning for production orders.
