Fusion Swiss-Type Post Processor for Sliding Headstock Lathes
Swiss-type lathes make small, precise parts at high volume, and their programs follow rules of their own. We build Fusion Swiss posts with guide bushing logic, moving headstock Z motion, gang tooling, back-working and two-channel synchronisation.
Swiss machines think differently
On a Swiss-type lathe, the bar moves through a guide bushing while the headstock slides in Z, and tools cut close to the bushing for high rigidity. Gang tools on the front, cross-working live tools and a back-working station on the sub-spindle can cut at the same time on separate channels. Programs often have two channels that wait for each other at sync codes, plus bar feed, cut-off and part ejection sequences.
ENGIMANDI builds Fusion Swiss posts that output this structure correctly: Z motion as headstock movement relative to the guide bushing, gang and cross tool selection, main and sub-spindle operations, channel sync codes, pick-off and cut-off sequences and end-of-bar handling. We work with Fusion's multi-channel and Swiss machine support and your builder's programming conventions for Citizen, Star, Tsugami, Nomura and others.

Swiss post questions
Can Fusion program Swiss-type lathes?
Yes. Fusion supports multi-channel machines and Swiss-style workflows, and a matching post produces the machine code.
How is Z handled with a guide bushing?
Z represents headstock movement relative to the guide bushing. The post outputs it according to your machine's conventions.
Can operations overlap on two channels?
Yes. Sync codes let front and back operations run at the same time where safe.
Do you support machines without a guide bushing?
Yes. Guide bushing-less modes can be supported where your machine offers them.
How long does a Swiss post take?
Swiss posts are complex; several weeks including proving is typical.
