Broaching units cut internal keyways, hexagons and squares on the lathe, removing the second operation on a broaching press or a slotting machine. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, builds them to mount on Okuma turrets, published for VDI30, VDI40, VDI60.
Developed specifically for the high-rigidity machining requirements of Okuma multitasking centers. These units are dedicated to integrating keyway and tooth profile machining into a single process, enabling the machine to handle internal/external splines and keyway cutting directly. Featuring a reinforced reciprocating mechanism, these units withstand high-frequency impacts, helping customers achieve high-efficiency process integration on their Okuma machines while protecting the turret drive system.
45 Okuma 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.
Already using another brand? Send the drawing or the article number of the holder you run today and Mongtec will convert it to an equivalent Mongtec holder — same mounting, same reach, same output.
