Method and device for producing bore holes in a planet wheel holder unit which are aligned to each other

摘要

The method involves generating a simultaneous position-accurate precision blanking in a precision blanking tool by the borings. The precision cut borings are finished in a forming tool by a simultaneous inner and outer ridge embossed at each boring edge (25) of the boring without reworking. An independent claim is also included for a device for producing borings in a planetary gear carrier unit for position accurate support of planetary gear axes for a gearbox.
