Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, supplies BMT and VDI (DIN 69880) driven tool holders, static holders and quick-change tooling for Mori Seiki CNC lathes and turning centres. Mori Seiki lathes remain in service worldwide under the pre-merger badge — the DuraTurn, SL/ZL, VL and ZT ranges are distinct from the post-2013 DMG MORI ALC, CL, CLX and NLX series, which are listed separately. Select your machine below, or send the model and a photograph of the turret face and engineering will confirm the interface.
| Machine model | Turret interface |
|---|---|
| DuraTurn 1530 | BMT / VDI — confirmed at RFQ |
| DuraTurn 2030, 2050, 2550 | BMT / VDI — confirmed at RFQ |
| DuraTurn 2050, 2550 MC | BMT / VDI — confirmed at RFQ |
| SL/ZL 150, 154 | BMT / VDI — confirmed at RFQ |
| SL/ZL 150, 154 MC/SMC/Y/SY | BMT / VDI — confirmed at RFQ |
| SL/ZL 200, 254 | BMT / VDI — confirmed at RFQ |
| VL-55, 553 | BMT / VDI — confirmed at RFQ |
| VL-55, 553 MC | BMT / VDI — confirmed at RFQ |
| ZT 1000 | BMT / VDI — confirmed at RFQ |
| ZT 1500 | BMT / VDI — confirmed at RFQ |
| ZT 2500 | BMT / VDI — confirmed at RFQ |
The interface is confirmed before quotation, not assumed from the label. BMT is an industry de-facto standard — it is not published by ISO or DIN — so two turrets both badged BMT55 can differ in bolt pattern, locating key and drive coupling. Send your machine model and a photograph of the turret face; Mongtec engineering checks it against the actual turret drawing. That check is free.
