OD static holders clamp turning tools for outside-diameter work — the non-driven stations of the turret, matched to the same bolt pattern as the driven holders. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, supplies them to mount on Miyano turrets.
Designed specifically for Miyano (Citizen-Miyano) high-performance automatic lathes. The housing is manufactured from high-quality alloy steel with precision machining and heat treatment, providing superior clamping rigidity. Tailored to the compact and high-precision interface requirements of Miyano turrets (such as the BNA, BNJ, and ABX series), these toolholders ensure long-term stability and excellent surface finish during both O.D. finishing and continuous mass production.
Build features
Compact & High-Rigidity Design — Optimized for the compact machining space of Miyano twin-turret machines, providing the necessary rigidity for heavy-duty cutting within a minimal footprint. It effectively suppresses vibrations, ensuring dimensional consistency under high-speed cutting.
Extreme Positioning & Repeatability — All mounting surfaces are ultra-precision ground to ensure perfect alignment with the Miyano turret. This not only shortens tool-change setup time but also meets Miyano’s rigorous standards for micron-level tolerances in precision part machining.
Optimized Internal Coolant System — The integrated coolant nozzle design directs fluid precisely to the cutting edge within tight spaces. This effectively reduces thermal drift caused by temperature rise and assists in rapid chip evacuation, maintaining stable quality during high-volume production.
Superior Wear & Corrosion Resistance — Surfaces undergo specialized strengthening treatments to effectively resist wear from cutting oils and metal micro-chips. This ensures the toolholder maintains interface integrity and precision during 24/7 continuous operation, reducing maintenance costs.
Seamless Miyano Compatibility — Fully compliant with Miyano OEM cylindrical or bolt-on turret interface specifications, ensuring easy installation and secure clamping. It helps customers maximize Miyano’s advantages in precision multitasking machining.
Miyano machines this holder is built for
8 Miyano models. Where the turret interface is published it is shown; where it is blank the interface depends on the turret actually fitted and is confirmed at enquiry.
The machine model alone does not decide the holder. The same model can leave the factory with
different turrets — station count, model suffix and key arrangement all change the mounting. Tell us the
machine, the turret and the operation and we confirm the mounting before quoting.
