Key principles.
Cross-features
Live tools cut cross-holes, flats, slots on rotating workpiece. Single setup completes parts.
Off-center features
Y-axis turn-mill enables off-center features impossible on standard lathes.
Backside machining
Sub-spindle picks up part for backside machining — both ends complete.
Continuous production
Bar-fed turn-mill runs unattended. Production volumes 200+ economical.
Single setup
One-setup machining preserves tolerance vs separate operations.
Round bar stock
Best for bar-stock material. Square/rectangle requires turning fixtures.
FAQ
Parts needing both turning (round geometry) and milling (cross-features) features. Single setup vs 2-3 separate setups dramatically reduces cost and improves tolerance.
True 3D milling on rotating parts. Off-center holes, complex 3D features. Premium over standard live-tool turn-mill.
Eliminates secondary operation for backside features. Both ends of part complete in single machine cycle.
Bar feeders enable unattended production. Lights-out machining with 200+ bar capacity. Per-piece cost drops significantly.
Bar stock material economical. Casting blanks need fixturing. Plate/forged stock typically not turn-mill candidate.
Standard turn-mill ±0.025 mm. Y-axis turn-mill ±0.025 mm. Tighter for ground bores or post-machined critical features.
