Star CNC Turning Centers — Mongtec Tooling Compatibility
Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies BMT and VDI (DIN 69880) turret tool holders. Star Micronics builds Swiss-type sliding-head automatic lathes (SR, SV, SX families) whose driven tools mount on a gang / Swiss interface confirmed per machine at RFQ. Pick your machine below, or contact engineering — the exact interface for a given model is confirmed at RFQ.

Interface data is drawn from publicly available machine specifications and tooling application listings. These are Swiss-type sliding-head machines whose driven tools mount on a gang / Swiss interface rather than a BMT/VDI turret; that interface is machine-specific and is confirmed per machine at RFQ. Mongtec's open-standard BMT and VDI holders apply to turret-type turning centers. Mongtec supplies open-standard BMT and VDI interfaces; it does not supply or claim compatibility with proprietary quick-change systems such as WTO QuickFlex®.
Also covered (send configuration for RFQ): other Star SR, SV, SW and SX-series sliding-head lathes.
Additional Star models covered
Mongtec supplies driven and static tooling for Star sliding-headstock (Swiss-type) turning centers. Swiss tooling is gang/sliding-head and machine-specific; the exact tool-station interface is confirmed at RFQ.
Mongtec Swiss-type toolholders for Star sliding-headstock lathes
Holders published in the Mongtec Swiss Type Toolholders, Ver 2026.07 catalogue for Star sliding-headstock (Swiss-type) lathes. Mongtec lists these against the Star machine-builder reference code, because a Swiss-type holder position is machine-specific and has no BMT or VDI size to quote.

Frequently asked questions
Does Mongtec make tooling for my Star Micronics machine?
Star Micronics builds Swiss-type sliding-head lathes (SR, SV, SX). Their driven tools mount on a gang / Swiss interface rather than a BMT or VDI turret, so tooling is machine-specific — send the model and we confirm what can be supplied at RFQ. For any turret-type turning centers in the range, Mongtec supplies BMT and VDI holders.
What is the difference between a Swiss-type and a turret lathe for tooling?
A turret lathe indexes tools on a BMT or VDI turret disc; a Swiss-type (sliding-head) machine holds tools on a fixed gang with sliding-headstock motion. Mongtec supplies BMT and VDI turret holders; Swiss gang tooling uses a different, machine-specific interface confirmed at RFQ.
My exact Star Micronics model isn't listed — can you still help?
Send the model name and configuration via the contact page and engineering will confirm what Mongtec can supply for that interface.
What does 'confirmed at RFQ' mean?
It means the exact interface is verified against your specific machine before quotation.
What precision and documentation do the holders ship with?
Driven holders are built to 0.003 mm runout or better.
Figures below are Mongtec's own published line specifications (mongtec-tools.com, accessed 2026-07-20). They describe the capability range of the product line; the rating of a specific unit for a specific machine is confirmed by Mongtec engineering at RFQ.
Turret interfaces supplied
BMT (face-and-taper), VDI polygonal shank to DIN 69880, and PSC polygon shank coupling to ISO 26623
Driven tool 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 published for the Mazak-compatible 0° driven tool line; other families confirmed at RFQ
No blanket published figure — quoted per order after interface, quantity and customisation are reviewed
On turret standards: VDI is codified in DIN 69880 and the PSC polygon shank coupling in ISO 26623. BMT (Base Mounted Turret) is a widely adopted de facto industry interface but is not published by ISO or DIN — two turrets both labelled “BMT65” can differ in detail between machine builders. Mongtec therefore verifies the actual turret dimensions of the stated machine before confirming fitment.
