Detailed Study of Spindle Drives for Boring Machines

This paper examines the main requirements for the electric drive systems of a class of boring
machines with digital program control. On this basis, a methodology for choice of the spindle drives is
offered. The algorithm takes into account the specific features of the technological processes, the
treated materials, the tools used and their wear, as well as the mechanical gear types. The
experimental studies of the implemented electric drives for the spindle are presented and discussed.
The analysis of their dynamic and static regimes of operation showed that such drives could ensure
good performance. The research carried out and the results obtained can be used in the development
of such drives for the studied class of machine tools.
