What Makes a Swiss Lathe Different
A
swiss lathe — also called a swiss turning center or sliding headstock lathe — works differently from a conventional
CNC lathe. In a standard lathe, the workpiece is clamped at the headstock and the cutting tools move into it. In a swiss machine, the bar stock feeds through a guide bushing directly next to the cutting zone, and the headstock slides along the Z-axis to advance the material. This keeps the cutting point supported at all times, which is why swiss machines can hold tolerances that would be impossible on a fixed-headstock lathe — especially on long, slender workpieces.
Most CNC swiss lathes run from a bar feeder, making them ideal for high-volume production. Parts drop complete (or near-complete) off the machine, often with the secondary spindle handling backside operations like drilling, threading, and cutoff before the part ejects into a bin.

Bar capacity is one of the most important specs to verify before buying. Most swiss lathes max out around 20mm to 32mm, though some larger models reach 38mm or 42mm. If you're running work above 32mm, verify the specific model's collet and guide bushing range — it varies.
What to Look for When Buying a Used Swiss Lathe
Buying a used swiss lathe requires more due diligence than a standard turning center. The tolerances these machines hold are unforgiving, which means wear shows up quickly in part quality.
| Inspection Point |
What to Check |
| Guide bushing wear |
Excessive wear causes chatter and out-of-tolerance parts — inspect for play |
| Collet condition |
Swiss collets are precision items; check for wear, damage, and proper grip |
| Spindle runout |
Measure at the spindle nose — anything over 0.0001" TIR warrants investigation |
| Bar feeder condition |
Check feed rollers, remnant sensors, and synchronization with the machine |
| Axis backlash |
Small amount expected on older machines — test each axis with an indicator |
| Control / software version |
Confirm the control is supported and can run your CAM post |
| Coolant system |
Swiss machines run high-pressure coolant — check pump, lines, and filtration |
| Tool holders / gang plates |
Replacement tooling for swiss machines is expensive — ask what's included |

Why Buy a Used Swiss Lathe from Premier Equipment
Swiss lathes are specialty equipment, and they're not cheap — even used. Prices for a used CNC swiss lathe typically range from $20,000 for an older single-spindle machine to $150,000+ for a late-model multi-axis Citizen or Tsugami with a bar feeder. New machines from the same brands run $200,000–$400,000 depending on configuration.
Premier Equipment has been selling used CNC machinery since 1988. Our facility in Altamonte Springs handles swiss lathes alongside our broader turning center and machining center inventory, which means you can compare across machine types with people who know the difference. We offer financing up to $500,000 on an application-only basis, with terms from one to six years — useful for a machine category where cash outlays are significant.
Frequently Asked Questions
What's the difference between a swiss lathe and a screw machine?
"
Screw machine" is an older term for the same general machine category — originally used because these machines were designed to produce screws and threaded fasteners at high volume. Modern CNC swiss lathes are the evolved version of cam-driven screw machines, with full computer control and multi-axis capability. You'll still see "swiss screw machine" used in listings, especially for older mechanical Tornos and Davenport-style equipment.
What bar diameter can a swiss lathe handle?
Most CNC swiss lathes are designed for bar stock up to 20mm or 32mm in diameter. Some larger models — certain Tornos and Tsugami configurations — handle up to 38mm or 42mm. If your parts require a specific bar diameter, always verify the machine's collet range and guide bushing bore before purchasing. Running oversized bar stock through an undersized guide bushing will damage the machine.
Do swiss lathes require a bar feeder?
Technically no, but practically yes for production work. Swiss lathes are designed for bar-fed continuous operation — that's the entire point of the sliding headstock. You can run short blanks manually, but you'll lose the cycle time advantage. Most used swiss lathes come with or have compatible bar feeders available. Ask us what's included with any specific machine.
Are parts and tooling easy to find for used swiss lathes?
It depends on the brand and age. Citizen, Star, and Tsugami have strong US support networks through their North American subsidiaries. Tornos parts are available but can carry longer lead times. Older cam-driven screw machines require more sourcing effort. Guide bushings, collets, and gang plate tooling are the consumable items you'll purchase most — confirm compatibility with your specific machine's collet size before committing.
