MPCNC Proxxon UF/E Mount

thingiverse

I've designed a tool mount for the Proxxon UF/E Spindle to use at the MPCNC Primo. As a base I used the Universal Tool Mount. The tool mount consists of 5 parts in total. The both main parts (lower and upper) are hold together by two 80 mm M6 bolts (Hex socket) fixed with a normal hex nut which you insert in the lower part. To clamp the tool you need three M5 bolts, which only need to be 15mm long. You counter them again with nuts. If you use the normal bolts to hold the bearings in place on the Primo Core you need to saw them off a little bit so that they are flush with the end of the nuts. Otherwise they would interfere with the spindle, because the holder was designed to get as close to the center as possible in order to avoid any long levers. The additional holder slides right into the holes of the upper part and was designed to provide an additional fixation point to eliminate any tilting when forces acting on the tool. I hope this helps someone.
