Improved vernier of longitudinal feed with measuring, for MN80 lathe

PROFI set for measuring the displacement of the main support for the MN80 lathe with an adjustable scale - vernier / with an adjustable zero - quick setting

The small gear in the photo is now newly supplied without a drilled hole - these diameters were machined differently on the MN80 lathes - therefore we recommend finishing it as needed and securing it with a suitable locking pin (locking pin not included).

Compared to the original, the set has an adjustable vernier - the possibility of setting zero as needed + locking with a threaded screw in the front of the wheel.

One part = 0.1mm
Turn of the main wheel = 24mm

Nonius has 240 parts on a diameter of 61mm, where the gap between the parts is 0.8mm and one part means 0.1mm of displacement. The description is from number 0 to 23 mm, a total of 24 mm per turn in the upward direction of rotation.

Eccentric bushings replace the original metal bushings for the gear shaft with the main handwheel, and the front bushing also serves as a vernier counter plate.
Eccentric bushings are encased in bronze.

The entire assembly is only 10mm longer than the original variant, and that is by the strength of the nonia counter plate.
The diameter of the hand wheel is the same as the original, but the wheel is much more massive.

The whole set has a massive impression and, thanks to the chosen materials, is also very rigid compared to Chinese plastic handwheels.

Exchange :
Replacement can be done only for the price of removing the support box practically only with a drill and M4 and M5 taps. See the attached instructions for more.
