- Guide-Bushing Support
- Turn-Mill Operations
- First-Article Inspection
Support Close to the Cutting Point
In guide-bushing mode, Swiss lathe machining uses a sliding headstock to feed bar stock through a support beside the tool. A short unsupported length helps stabilize slender features.
Reduced Deflection
Close support helps limit bending, chatter, taper, and diameter variation on slender sections.
통합 기능
Turned diameters, flats, slots, cross holes, and threads can share a coordinated machining route.
Rear-Side Completion
Sub-spindle transfer allows rear faces, bores, and chamfers to be finished before release.
반복 가능한 생산
Automatic bar feeding, tool-life control, and a stable cycle support consistent repeat orders.
Precision Parts Made from Bar Stock
Swiss machining is well suited to rotational parts with slender sections, repeated features, or close relationships between turned and milled details.

스위스 CNC 가공 자주 묻는 질문
How does Swiss machining differ from conventional turning?
In guide-bushing mode, the sliding headstock moves bar stock through a support close to the tool. This limits unsupported length on slender parts. Conventional turning generally holds exposed stock in a chuck or collet and is often economical for short, rigid components.
Is Swiss screw machining limited to screws?
No. The term refers to Swiss-type automatic machining rather than a screw-only process. It is also used for precision shafts, pins, bushings, fittings, and other parts with combined turned and milled features.
Can Swiss machining produce prototypes?
Yes. It is useful when a prototype requires close support, integrated driven-tool features, or validation of a route intended for repeat production. Simple one-off parts are reviewed against conventional turning for cost.
What tolerances can be achieved?
There is no single tolerance for every part. Diameter, length, material, bar quality, thermal stability, and measurement access affect the result. Critical requirements are confirmed through drawing review and first-article inspection.
How are internal cross-hole burrs controlled?
The route considers tool direction, edge-break geometry, tool condition, and deburring access. Internal intersections receive an application-specific method and inspection criteria based on flow, assembly, and mating-part requirements.
What determines cost and production lead time?
Material, bar availability, quantity, setup, cycle complexity, tolerances, deburring, finishing, and documentation all affect the schedule and quote. Shipment timing is confirmed after the technical requirements are agreed.
Can rear-side features be completed in the same cycle?
On a suitable sub-spindle machine, the part is transferred before cutoff for rear-side operations. The final sequence depends on geometry, tool access, clamping surfaces, and inspection needs.
