Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, manufactures BMT and VDI (DIN 69880) driven and static tool holders. Citizen Machinery builds two families: Miyano fixed-headstock turret turning centers (BNA, BNE, BNJ) that use BMT turrets, and Cincom Swiss-type sliding-head lathes (L, M, D, R series) that use a gang / Swiss interface. Pick your machine below, or contact engineering — the exact interface for a given model is confirmed at RFQ.
| Series | Type | Mongtec supply |
|---|---|---|
| Miyano BNA / BNE / BNJ | Turret turning center | BMT holders — size at RFQ |
| Cincom L / M / D / R | Swiss-type sliding-head | Gang / Swiss interface — confirmed at RFQ |
Interface data is drawn from publicly available Citizen / Miyano machine specifications and tooling application listings. Mongtec's BMT and VDI holders apply to the Miyano turret turning centers; the Cincom Swiss-type machines use a machine-specific gang interface confirmed at RFQ. Mongtec supplies open-standard BMT and VDI interfaces; it does not manufacture or claim compatibility with proprietary quick-change systems such as WTO QuickFlex®.
For Citizen Miyano turret turning centers, see the dedicated Miyano compatibility page. Cincom Swiss machines: send the model for RFQ.
For Citizen Miyano turret turning centers (BNA, BNE, BNJ), yes — Mongtec supplies BMT holders. For Cincom Swiss-type sliding-head lathes, driven tools use a gang / Swiss interface confirmed per machine at RFQ.
Miyano is Citizen Machinery's fixed-headstock turret turning-center brand. Mongtec has a dedicated Miyano page covering the BNA, BNE and BNJ BMT-turret machines.
Miyano BNA and BNE turret turning centers use BMT-pattern disc turrets; the exact size is confirmed per machine at RFQ. See the Miyano page for details.
Cincom L, M, D and R machines are Swiss-type with gang tooling; that interface is machine-specific. Send the model via the contact page and engineering will confirm what can be supplied at RFQ.
Driven holders are built to 0.003 mm runout or better and ship with an individual inspection report.
