FIELD: metal processing.
SUBSTANCE: invention can be used, for example, for making grooves on the surface. Power head (1) for cutting workpieces (2) for machining comprises processing tool (3), installed or made in body part (5) of power head (1) with possibility of movement in horizontal movement plane (E), at least one drive unit (4a–4b) for movement of processing tool (3), located or made on body part (5) or in body part (5) of power head (1). Drive assembly (4a–4b) is configured to provide a combined movement of processing tool (3) along a first path and a second movement path different from the first path, and processing tool (3) is installed with possibility of trochoidal or cycloidal displacements relative to body part (5) on at least two different combined trajectories of movement.
EFFECT: use of the invention improves the accuracy of processing.
