Supported Nakamura-Tome models

FAQ

Which turret interface do Nakamura-Tome lathes use?

It depends on the machine, not on the brand. Across the 89 Nakamura-Tome models documented on this site the published interfaces are: BMT44 on 56 models (such as NTJ-100 (lower turret), NTJ-100 - upper turret, with face tooling, NTJ-100 - upper turret, without face tooling); VDI40 on 52 models (such as SC-250, Super NTJ, WT-250); BMT55 on 49 models (such as JX-200, JX-250, NEWTW 30); BMT65 on 49 models (such as JX-200, JX-250, NEWTW 30); BMT45 on 20 models (such as AS-200 (12-station), AS-200 (15-station), AS-200L (12-station)). A further 10 models are not yet published with an interface and are confirmed per configuration at RFQ. Some models appear under more than one interface because the same designation ships with different turret options. Send the model designation and turret station count and Mongtec engineering confirms it against the actual turret drawing.

Is Nakamura-Tome's BMT44 / BMT55 / BMT65 the same as standard BMT?

No. Nakamura-Tome uses its own BMT44, BMT55 and BMT65 designs, which are not interchangeable with catalogue-standard BMT of the same nominal size — standard BMT article numbers will not fit. Mongtec supplies Nakamura-specific interfaces regularly; send the model and turret station count and engineering confirms the correct design before quoting. Where a Nakamura machine is listed with VDI40, that is standard VDI40.

Will a Mongtec driven tool holder fit my Nakamura-Tome turret?

Mongtec supplies on the same open machine-side standards Nakamura-Tome turrets use — BMT face-and-taper, VDI polygonal shank to DIN 69880, and PSC polygon coupling to ISO 26623. Because BMT is an industry de-facto standard rather than an ISO or DIN standard, fitment is confirmed per machine: send the model designation and turret station count (a photo of the turret face or the machine spec sheet helps) and Mongtec engineering confirms it against the actual turret drawing before quoting.

My Nakamura-Tome model is not in the list above — can you still supply?

In most cases yes. The list covers models already documented by Mongtec; it is not the limit of what Mongtec can supply. Custom and special-configuration units are a standard part of the work, and Mongtec supplies turret interfaces beyond the article numbers published on this site. Send the model designation and turret station count and engineering will confirm.

Do you supply static holders and boring bar holders as well as driven tools?

Yes. Static turning, boring bar, facing, cut-off and blank holders are supplied on the same turret interfaces as the driven units, alongside quick-change tooling and angle heads.

What quality documentation ships with the tooling?

Every driven unit ships with an individual inspection report for that specific unit — measured values, not a generic batch certificate.

What is the lead time?

Mongtec does not publish a blanket lead time. It is confirmed according to the items and quantities the customer requests, once interface, quantity and any customisation are reviewed. Request a quote for a project-specific answer.

Does Mongtec repair driven tools from other brands used on Nakamura-Tome machines?

Mongtec's Taiwan service centre works on driven tool holders and angle heads. Whether a specific third-party brand and model is covered is confirmed case by case on request.

Turret interfaces across the NAKAMURA TOME range

Turret interfaces for the 23 NAKAMURA TOME models on this page are confirmed at RFQ. Published machine-builder specifications do not state the interface consistently enough for us to print it here, and printing a guess would be worse than printing nothing — a holder ordered against a wrong interface does not mount.

What we need to quote a NAKAMURA TOME machine

Three things get you a firm quote: the machine model and year, a photograph of the turret face, and the tools you intend to run (drill and tap sizes, or end mill diameter). Anything you do not know we work out from the machine model — an incomplete enquiry is still worth sending, and the interface check costs you nothing.
