Swiss CNC Machining for Slender Turned Parts
Swiss CNC machining supports bar stock in a guide bushing close to the cutting edge, so long, slender pins, shafts, and threaded components stay rigid and hold tight tolerance over long lengths. What CNC Swiss machining is covers the full mechanics.
Turning, milling, and drilling combine in one setup with no MOQ: a single validation part and a full production run follow the same manually reviewed process. Swiss turning runs alongside milling, EDM, and grinding under DEK’s machining services, so secondary operations need no extra vendor.
Why Choose DEK for Swiss Turning Services
Two decades of precision machining, more than 1.2 million parts a year and 2,300+ OEM clients stand behind every Swiss-turned part.
-
On-Time Delivery
On-time delivery holds above 98.6%, backed by documented QMS stages on every job: IQC, IPQC, FAI, OQC, SPC, and CAPA.
-
Certified Quality System
ISO 9001, ISO 13485, and AS9100D certification via TÜV, covering medical, aerospace and industrial Swiss-turned components.
-
In-House CMM Inspection
In-house CMM inspection with full traceability documentation, so tolerances down to ±0.003 mm are verified before parts ship.
-
3-Day Prototypes
Once confirmed, prototypes ship in 3 days before production tooling is committed, then production runs through the same inspection stages.
Manual Engineering Review
Every quote is reviewed by an engineer, not an automated per-second calculator. Automated cutting-time tools miss tolerance and finishing requirements on small turned parts, which inflates quotes or scrap rates.
Swiss Machining Capabilities & Tolerances
Guide-bushing support, combined operations and bar-fed secondary work, from single prototypes to high-volume screw machining runs.
Swiss Machining vs. Other Turning Processes
Choose Swiss turning for small-diameter, high length-to-diameter parts run in volume. The Swiss machining cost page breaks down setup and batch-size drivers.
| Criteria | This ProcessSwiss Machining | Standard CNC Turning | Micro Parts Machining |
|---|---|---|---|
| Best for | Long, slender small parts | Larger shafts, housings | Sub-millimeter features |
| Diameter | Up to roughly Ø32 mm | Above roughly Ø32 mm | Sub-mm features |
| Setup | Guide bushing, tool change | Skips guide-bushing setup | Outside screw-machine run |
| Volume | Volume runs off bar stock | Short runs, one-off parts | Per drawing |
| Choose when | High L/D, tight tolerance | Larger or short-run parts | Features below 1 mm |

Typical Swiss-Turned Parts & Challenges
Swiss turning excels at small threaded, stepped and slender parts that a standard lathe struggles to hold to tolerance.
-
Custom Screws & Fasteners
Custom screws and threaded fasteners with M1–M20 metric or #0–3/4" UN/UNF threads, rolled or cut in the same run.
-
Bone Screws & Cannulas
Bone screws, cannulas and instrument shafts in 316LVM or Ti-6Al-4V, held to ±0.003 mm on sub-10 mm features.
-
Pins & Standoffs
Structural pins and standoffs for non-flight-critical cabin hardware, part of aerospace parts manufacturing.
-
UHP Fittings
316L fittings for UHP gas and fluid lines, the work behind our precision ultra-high purity fittings.
-
Carbon Steel Pins & Shafts
Carbon steel turned parts hold dimension in load-bearing assemblies that need no stainless-grade corrosion resistance.
-
Bushings, Seals & Insulators
Small turned bushings, spacers, insulators and seals in metals or engineering plastics such as PEEK and PTFE.
Common Challenges We Handle
-
Long, Slender Parts
Guide-bushing support keeps bar stock rigid close to the cutting edge, so high length-to-diameter parts are machined without a steady rest.
-
Micro Features
Sub-10 mm features hold ±0.003 mm; sub-millimeter work outside a standard screw-machine run moves to micro parts machining.
-
One-Setup Complex Parts
Turning, milling, and drilling combine in one setup, while cross-drilling, slotting and knurling run in the same pass without a second setup.
-
Setup Cost vs. Volume
Swiss setups add cost on larger or short-run parts; send your drawing and annual quantity and engineers place the part on the right equipment class.
