Long, slender and miniature turned parts held to ±0.005 mm on CITIZEN sliding-headstock lathes — turning, milling, cross-drilling and threading finished in one setup, from a few hundred pieces to a million.
Swiss turning is ideal for miniature components and is especially effective for producing long, slender parts. Multiple operations — milling, turning, threading, cross-drilling, engraving and more — are completed on a single machine, reducing costly secondary processing, saving time and lowering cost while every part is manufactured to precise specifications.
Components made through Swiss turning are widely used in aerospace, electronics, energy and fuel systems and medical devices. Common examples include shafts, contact pins, housings, inserts, sockets, implants and related products.
From small batches of a few hundred pieces to high-volume production in the hundreds of thousands, our CITIZEN machines produce complex components on a single machine to meet unique design specifications — even for highly demanding applications.
For 1,000 to 1,000,000-piece production runs of components up to Ø 32 mm that combine turned and milled features, in metal or plastic — especially where straightness and concentricity tolerances, high-quality finishes and repeatable quality are required.
CITIZEN sliding-headstock machines, ISO 9001:2015 and IATF 16949 process control, and unattended production for consistent quality on every miniature part.
The workpiece is supported right next to the cutting tool throughout the process, giving exceptional stability and tolerances of ±0.005 mm or better — even on very small, delicate parts.
Superior surface quality straight off the machine, so most parts need little or no secondary finishing before they ship.
Fast cycle times and unattended running make Swiss turning perfect for high-volume production of miniature components, with shorter overall lead times.
Turning, milling, drilling and threading performed simultaneously — thin walls, fine details and deep features that standard CNC machines struggle with.
A highly efficient process that reduces scrap and lowers material cost on every run — cost-effective for precision parts.
Consistent quality across large production runs, with ready-to-use parts shipped directly from the machine with minimal additional processing.

We stock a range of alloys and plastics suited to a wide variety of part applications and industries. Special alloys arrive with mill certificates, and every lot ships with its material certificate on request.
Material certificates are checked against the drawing and the heat number is recorded at receiving, so every lot is traceable from raw stock to the box it ships in.
The first part off the machine is measured feature by feature against the drawing and released with a first article inspection report before production continues.
Operators sample parts throughout the run with statistical process control and AQL checks, so any drift is corrected at the machine — not discovered at the end.
Every part receives a final dimensional and visual inspection, is packed with VCI protection and ships with its inspection report and material certificates.
A sample of the miniature part families we run every week. Customer-specific work is never shown without written permission.
