Abstract

Intended is to perform the cam adjustment of a cam type lathe easily. The movement of a blade (21) in a cutting direction is controlled by a cam mechanism (10), and the movement of a spindle stock (2) in a Z-axis direction is numerically controlled by a servo-motor (6). A lathe (1) detects the rotating angle, the rotating speed and so on of a camshaft (16) with sensors. On the basis of the values detected, moreover, the lathe (1) controls the movement of the spindle stock (2) so that it can move the cam mechanism (10) and the spindle stock (2) synchronously. On the other hand, a ball screw (7) and a nut (8) are arranged so that the driving force in the Z-axis direction by the servo-motor (6) may act homogeneously on a slide face (17), thereby to prevent the heterogeneous wear of the slide face (17). Thus, the lathe (1) controls the spindle stock (2) numerically, and separates the same from the cam mechanism (10), thereby to facilitate the adjustment of the cam mechanism (10) and the setting of the offset value of the spindle stock (2).
