What M7106 does on the machine

The driven spindle points at 90° to the lathe spindle, along the X axis. This is the configuration for cross drilling, cross tapping and slotting on the outside diameter.

Direct drive. The turret drive shaft couples straight into the tool spindle with no intermediate gear train. Fewer moving parts, less backlash and a stiffer path from the turret motor to the cutter — generally the better choice when surface finish and hole position matter.

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.

Right-hand version. Handedness has to match the turret rotation and the station you intend to use; the opposite hand will index into the wrong quadrant.

Do not order against the label alone. “VDI20” fixes the shank per DIN 69880, but pocket depth, clamping system and drive coupling still vary between machine builders. Send Mongtec your machine model and a photograph of the turret face — engineering checks M7106 against the actual turret drawing before anything is quoted. That check is free and takes one email.

Frequently asked

What machines does the Mongtec M7106 fit?

M7106 is built for the VDI20 turret interface. Because VDI shank dimensions follow DIN 69880, but turret pocket depth, clamping system and drive coupling still vary between machine builders. 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 M7106 run?

M7106 is rated to 6,000 rpm with 25 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 M7106 take?

M7106 takes ER20 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 M7106?

Yes. Mongtec supplies the full dimensioned drawing for M7106 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 M7106 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 M7106 are supplied by email once the enquiry is open.
