What M3227 does on the machine

The driven spindle points along the Z axis, parallel to the lathe spindle. This is the configuration for face drilling, face tapping and end milling on the part face.

Through-coolant. Coolant is routed inside the holder and delivered at the cutting edge through the collet and tool. For deep-hole drilling and tapping in stainless or titanium this is usually the difference between a tool that survives the cycle and one that does not.

Gear ratio 1:1 — tool spindle speed equals turret drive speed. The direct relationship makes speeds and feeds straightforward to calculate from the machine's live-tool rating.

Do not order against the label alone. “BMT65” identifies the nominal turret class, but BMT is an industry de-facto standard — it is not published by ISO or DIN. Bolt circle, key position and drive coupling can differ between machine builders at the same nominal size. Send Mongtec your machine model and a photograph of the turret face — engineering checks M3227 against the actual turret drawing before anything is quoted. That check is free and takes one email.

Machines with a BMT65 turret

Mongtec publishes tooling pages for these machines with a declared BMT65 turret. Confirming your model here does not confirm M3227 as the article number — that still comes from engineering.

Frequently asked

What machines does the Mongtec M3227 fit?

M3227 is built for the BMT65 turret interface. Because BMT is an industry de-facto standard rather than an ISO or DIN published standard, bolt circle, key position and drive coupling can differ between machine builders even at the same nominal size. Send Mongtec your machine model and a photo of the turret face and engineering confirms the fit before anything is quoted.

What speed and torque can M3227 run?

M3227 is rated to 6,000 rpm with 70 Nm of torque at a 1:1 drive ratio. The usable figure is whichever is lower: this rating or your machine's live-tool drive rating.

What collet does M3227 take?

M3227 takes ER32 collets. Collets and nuts are supplied separately; specify the shank diameters you intend to run and Mongtec quotes the collet set with the holder.

Is a dimensioned drawing available for M3227?

Yes. Mongtec supplies the full dimensioned drawing for M3227 by email once an enquiry is open, so the drawing is matched to your actual machine and turret configuration rather than a generic sheet.

Get M3227 quoted

Send the machine model, the turret station you want to use and the tools you intend to run. Anything you do not know, Mongtec works out from the machine model — an incomplete enquiry is still worth sending. Dimensioned drawings for M3227 are supplied by email once the enquiry is open.
