Abstract
A rotary tool generating head with radial tool slide feed-out produced by differential rotation of central shaft. A harmonic drive gear having a stationary axle and a servo motor driven rotary axle is used to produce zero feedout of the radial slide when the servo driven axle is stationary. Servo controlled radial tool displacement occurs through rotation of the servo driven axle with a substantial reduction in rotational speed with respect to the stationary axle, e.g., in the order of 97:1.
