Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies driven tool holders and static tooling for the Nakamura-Tome Super Mill SC-200L on the open machine-side BMT and VDI (DIN 69880) standards. The turret interface for this model is confirmed per machine configuration by Mongtec engineering at RFQ, and every driven unit ships with an individual inspection report.
| Machine brand | Nakamura-Tome |
|---|---|
| Model | Super Mill SC-200L |
| Turret interface | Not published for this model yet. Nakamura-Tome turret rule: the BMT44, BMT55 and BMT65 turrets on Nakamura machines are Nakamura-specific designs — standard catalogue BMT holders do not fit them. Mongtec supplies holders to the Nakamura interface and supplies them regularly. Where a Nakamura machine carries a VDI40 turret, standard VDI40 applies. Send the machine model, station count and a turret photo — Mongtec confirms the interface free of charge. |
| Driven tool line speed | 6,000–12,000 rpm standard (up to 32,000 rpm with speed increaser) |
| Max torque | Up to 160 Nm (line capability; unit rating confirmed at RFQ) |
| Coolant | Internal / external, up to 100 bar |
| Runout | ≤0.003 mm (0° axial driven line) |
| Quality assurance | Each driven unit ships with an individual inspection report |

Mongtec also supplies BMT40, BMT60, BMT68 and BMT80 holders and builder-specific interfaces (Mazak, Nakamura-Tome, Haas BOT, Okuma BOT, Muratec BOT) — the 228 article numbers published here are a subset of the range. Mongtec tooling is exported to five continents and supplied to machine-tool builders. Lead time is confirmed per item and quantity at quotation.

Mongtec supplies BMT and VDI (DIN 69880) driven tool holders and static tooling compatible with the Nakamura-Tome turret platform. Interface: Confirmed per machine configuration at RFQ. The exact configuration is confirmed by Mongtec engineering at RFQ.
Yes. BMT and VDI are open machine-side standards, so switching supplier does not require any turret modification. Mongtec also publishes cross-reference pages for WTO, Heimatec, EWS, Eppinger, BIG and other brands.
Lead time is quoted per order and ships from Taichung, Taiwan. Every Mongtec driven tool holder is inspected before shipment (runout, torque, balancing) and ships with an individual inspection report.

We have not published an interface for this model because the public machine specifications do not state it consistently, and a guessed figure is worse than a blank field. Three steps settle it:
BMT is not published by ISO or DIN, so even the marking in step 2 is a starting point, not proof. The drawing decides.
Machine builders routinely ship the same model with more than one turret. These are all published, verified examples:
| Machine | What changes | Turret mounting |
|---|---|---|
| Hardinge Conquest H51 | station count | 12-station = BMT55 · 16-station = BMT45 |
| Okuma GENOS L300 | model suffix | L300 M = VDI40 · L300 MW/MYW = 65×73 bolt pattern |
| DMG MORI ALC / ALX 1500–2500 | turret build | BMT40 or BMT42/64 |
| DMG MORI NZX 2500 | turret build | BMT40 or BMT60 |
| Takisawa TS-3000 / 4000 | key count | 2-key and 3-key turrets are not interchangeable |
This is why a published spec sheet cannot answer the question for every machine, and why Mongtec verifies the turret drawing before quoting rather than selling against a nominal size. It is also the most common reason a driven tool holder arrives and will not bolt on.

Machine builders regularly ship the same model with different turrets — station count, model suffix and the number of keys all change the mounting. The Hardinge Conquest H51 is BMT55 in the 12-station build and BMT45 in the 16-station build; the Okuma GENOS L300 M is VDI40, while the L300 MW/MYW uses a 65×73 mm bolt pattern. This is the single most common reason a driven tool holder arrives and will not bolt on. BMT bolt pattern reference — 38 patterns by machine builder →

The turret interface for this machine is confirmed at RFQ, so no article number is published here. These are the driven tool types Mongtec publishes — which one fits is confirmed once the turret is identified.
