Swiss-Type vs Turn-Mill: Choosing the Right Process for Long Slender Shafts
A practical comparison of Swiss-type lathes and turn-mill centers for long, slender, tight-tolerance shafts — when each wins on roundness, taper, and cost.

Swiss-Type & Precision CNC Turning for Long Slender Parts
In-house at our Dongguan facility, with dimensional inspection by optical measuring systems, height gauges and calipers.
Overview
Swiss & Precision Turning
A Swiss-type lathe supports the workpiece with a guide bushing right at the cutting point, which is why it can hold diameter on a shaft 20 times longer than it is wide. A conventional lathe gripping the same part would let it deflect and chatter.
We run sliding-head and Swiss-type turning machines for bar work up to Ø32 mm, with live tooling and Y-axis; the Swiss machines add sub-spindles for back-working, so a part comes off the machine complete rather than needing a second operation to finish the back end.
When Swiss Is the Right Answer
If your part is long and thin, small and high-volume, or needs work on both ends, Swiss turning is usually cheaper per part and more accurate than anything else on the floor. If it is short and chunky, a standard lathe is faster to set up and the hourly rate is lower.

What We Make
Typical Parts & Scope
- Long slender shafts with length-to-diameter ratios above 8:1
- Micro parts and miniature turned components
- High-volume turned parts where cycle time decides the price
- Electronic pins, contacts and connectors
- Parts needing back-working on the sub-spindle
