ABSTRACT:
A machine tool including an elongate bed with front and rear ends and a longitudinal axis, a spindle with a work piece-engaging chuck at the rear end of the bed, a first motor driving the spindle, a carriage at the front end of the bed, a first drive means with a second motor to position and move the carriage longitudinally of the longitudinal axis, an elongate cross-slide carried by the carriage and carrying a tool holder, a second drive means with a third motor to position and move the cross-slide on a lateral axis, an encoder connected with and reading the rotative position of the spindle, an electric-powered computerized primary controller connected with the encoder and with the first, second and third motors and controlling the operation thereof in response to machining programs stored therein; a rotary cutting tool head including an elongate rotary cutting tool holder driven by a fourth motor is mounted on the cross-slide remote from the cutting tool holder; a second electric-powered computerized controller is connected with the encoder, the primary controller and with the fourth motor and in which is stored a program which when processed thereby controls the direction of rotation, the rotative position and the ratio of rotation of the cutting tool holder relative to the rotation of the spindle in response to each signal in machining programs stored in the primary controller and received by the secondary controller and that directs the rotary cutting tool holder to be put into operation.
