A cutting/milling head device (1) of the type connected to a cutting machine/milling machine (2), and where the cutting/milling head (1) is designed, when in operation, to be able to change the angle of a cutting tip/the mill (76) relative to a central axis (8a) while at the same time rotating the cutting tip/mill (76) about the same central axis (8a), and where e.g. an axially movable spindle (8) is equipped with at least one toothed rack (68) in engagement with at least two cogwheels (66), where the cogwheels (66) via at least two shafts (62) rotatably mounted to a rotational sleeve (10) are connected to their respective, mutually parallel lower elbow lever (60a) and upper elbow lever (60b), the elbow levers (60a, 60b) at opposite end portions being hinged to a parallel lever (72), and where the lower end portion of the parallel lever (72) is hinged to a cutting tip holder (75), the hinge joints of the parallel lever (72) to the elbow levers (60a, 60b) and the cutting tip holder (75) having parallel axes. A first disc/cogwheel (74) is rigidly mounted via a shaft (70a) to the lower elbow lever (60a), where the shaft (70a) constitutes the hinge joint to the parallel lever (72), and a second disc/cogwheel (78) is rigidly mounted to and the cutting tip holder (75) at the hinge joint to the lower portion of the parallel lever (72), the two discs/cogwheels being interconnected by means of a belt/chain (80), whereby the cutting head (1) is designed so that the direction of cutting of the cutting tip always faces a pivot point (82). |
