Abstract:
A multiple-spindle machine comprising:a support,a number of spindles rotatably mounted to and with respect to said support, each spindle being rotatable about a respective longitudinal axis,each of said spindles operably connected and in driving relationship to a respective one of a like number of cutters,each of said cutters having a number of cutting edges, said number of cutting edges of each of said cutters being two or more,each of said spindles operably connected to a respective one of a like number of individually controllable electric motors for rotatably driving each of said spindles respectively,control means for controlling a speed of each of said electric motors and an angular position of each associated spindle and cutter about said associated longitudinal axis thereof, andphase control means for adjusting said speed and said angular position of each of said spindles such that said cutting edges of each of said cutters are at different angular positions than, and are thus out of phase with, each of said cutting edges of others of said cutters during operation of the multiple-spindle machine.
