Abstract

PURPOSE:To obtain an economical and space-saving machine tool without spoiling performance and function, by switch-controlling a main shaft motor and a mill motor with one main shaft amplifier. CONSTITUTION:By a detection signal switching circuit 3, contacts b and d are turned ON when a main shaft motor 5 is driven, and contacts (a) and c are turned ON when a mill motor 15 is driven. By a power line switching circuit 4, a contact e is turned ON when the main motor 5 is driven, and a contact f is turned ON when the mill motor 15 is driven. For a main shaft amplifier 1, a parameter for determining the controlling characteristic of two motors is prepared. In this manner, by switching contactors, speed detecting signal, and the control parameter, either one of the main shaft motor 5 or the mill motor 15 is controlled with one main shaft amplifier 1.
