Doosan Series Repair
Doosan Swiss-Type / DST Spindle Repair & Grinding
Doosan Swiss-type spindles — SwiftTurn 32 and 38, the DST series — handle high-precision small-diameter bar work. Swiss-type spindle service interacts with guide bushing wear in ways straight turning doesn't; the two are often companion jobs. Sub-spindle synchronization on twin-spindle Swiss platforms needs careful verification post-rebuild.
Models in this series we service
- SwiftTurn 32
- SwiftTurn 38
Common failure patterns
- Guide bushing wear interacting with spindle service.
- Sub-spindle synchronization drift on twin-spindle Swiss configurations.
- Bar feeder synchronization issues affecting spindle-side cuts.
- Live tool indexing on multi-tool variants affecting spindle-side alignment.
Controls used on this series
Doosan Swiss platforms ship on Fanuc 30i (Doosan).
Lead time
Lead time depends on the model, the failure mode, and parts availability. Diagnostic is fast; full rebuilds run 3 to 5 weeks on most jobs. We scope each job individually rather than quoting a generic window.
