Project of instrumentation of cyclic multiple-spindle driller aimed at improving its machining efficiency

The basic element of each multiple-spindle driller is its working unit also called drilling head. The use of multi-spindle drill heads enables simultaneous drilling of holes arranged in rows, which makes such drillers much more efficient than one-spindle drillers. However their defect is the lack of possibility to make holes in stud elements. Passage drillers are particularly affected by this problem and this is why research on this machine-tooling was undertaken. The project enables widening technological possibilities of multiple-spindle /gang/ drilling machines. This paper deals with the presentation of some types of tooling.
