Abstract
A machine for the precision working of tooth surfaces on toothed workpieces. The machine has a frame, a rotatingly drivable gearlike tool which is arranged substantially above the workpiece on the frame and structure supporting the tool for movement into a tooth engaging relation with the workpiece. Structure is also provided for adjusting a crossed-axes angle between the tool and the workpiece. Guide structure is provided for effecting a change in the spacing between the geometric centers of the tool and the workpiece during a machining operation. The workpiece is stationarily mounted on the frame and all guideways on the frame required for facilitating an adjustment of the tool and during the working operation are arranged substantially above the workpiece. Additional structure is provided for facilitating an adjustment of the axis of rotation of the tool about both horizontal and vertical axes.
