Disclosed herein is a hobbing machine particularly for the production of spur and helical gears. The hobbing ma- chine is characterized in that a separate mechanism for hob shifting is not required. The hob shifting, as well as other ma- chine motions, is carried out by linear movement of the tool (41) and workpiece (74) relative to one another in up to three mutually perpendicular directions. The machine also in- cludes tool support means (30) to which the hobbing tool (41) is mounted and which is rotatably adjustable for controlling the angular orientation of the hobbing tool (41). A control system including a computer controls the linear movements, angularly adjustable tool support (30) movements, as well as the necessary timed rotations of the tool (41) and workpiece (74).
