We actively hold parts in stock for the TWIN series below. Other Twin configurations or CTX TWIN — we research on request.
Classic TWIN series for 32 mm bar stock. Largest documented parts holding.
Larger bar capacity variant. All-round twin-spindle lathe.
Heavy TWIN class. Rigid bed construction.
Classic 300 variant with twin-spindle layout.
Larger 500 variant. More axis travel for longer workpieces.
RG2 variant with extended synchronisation option.
// Symptom instead of part number?
We narrow it down by phone.
Sync axis drift, chuck synchronisation, twin-spindle faults — with Twin / MF Twin symptoms, diagnosis is a matter of listening, not of ordering parts. 5–10 minutes on the phone usually prevent the wrong replacement.
// FROM THE WORKSHOP
What usually goes wrong
on twin-spindle machines.
Axis synchronisation is the tricky part of the TWIN series.
When the main and sub spindle no longer run exactly in sync, the mechanics are rarely to blame. Usually it is the encoder, a cable or the drive control. We narrow it down by phone before we come out on site.
Two spindles = twice the bearing risk.
In TWIN machines both spindles are often loaded identically. If one has bearing damage, the other usually does too — we recommend measuring both together rather than reworking them one at a time.
Twin-turret drives are repairable.
Tool turret drives on the TWIN series (Sauter, Duplomatic) are often no longer available from the manufacturer as a complete exchange unit. We strip the drive down, replace bearings, coupling and encoder, and test it under load.
A full overhaul often pays off.
A TWIN is an expensive machine — a full overhaul is usually cheaper than a replacement. We discuss the effort involved and the residual value with you in person beforehand.
