ABSTRACT:
A multiple-spindle machine includes a support and a number of spindles rotatably mounted to the support. Each of the spindles is operably connected and in driving relationship to a respective one of a like number of cutters, each of the cutters having two or more cutting edges. Each spindle is operably connected to an individually controllable electric motor. A controlling device controls the speed of each electric motor and the angular position of its associated spindle. A phase control device adjusts the speed and the angular position of each of the spindles such that the cutting edges of each of the cutters are out of phase with each of the cutting edges of others of the cutters during operation of the multiple-spindle machine. Angular position and speed detecting devices are used for detecting angular positions and speeds of each of the spindles. The angular position and speed detecting devices are in signal transmitting relationship with the phase control device. In a preferred embodiment of the invention, the phase control device is programmed to adjust speed of the spindles such that cutting edge angular positions are out of phase by an amount equal to 360 degrees divided by product of the number of the spindles and the number of cutting edges of each of the cutters.
