A machining unit for machining, in particular turning and/or milling, workpieces, in particular elongate workpieces, in particular shafts, includes a machining tool. The machining tool can be moved along at least two different, in particular combined, motion paths in a motion plane. The machining until also includes at least one drive unit, which is designed for moving the machining tool along a first motion path and along a second motion path, which is different from the first motion path, possibly in a combined manner.

A handheld machining device (1), particularly for drilling, having a mechanism includes: a first mounting (20), on which a tool holder (2), and a motor (3, 4) arranged to rotate the tool holder (2), are mounted; a second mounting (30); and an element (40) for translatably guiding, between the first mounting (20) and the second mounting (30), a linear actuator (5) enabling the first mounting (20) to be spaced apart from the second mounting (30), and the first mounting (20) to be brought toward the second mounting (30). The motor (3, 4) is electric, and the rotor (4) of the first motor (3, 4) is directly mounted onto the tool holder (2) and is rigidly connected thereto.

Actuators, systems, and methods for controlling tools are disclosed. One actuator includes a first motor, a second motor, and a controller. The first motor is operable to rotate a first threading extending in a first helical direction around an axis. The second motor is operable to rotate a second threading axially spaced apart from the first threading and extending in a second helical direction opposite the first helical direction around the axis. The controller is in communication with the first and second motors. The controller is configured to control speed and direction of the first and second motors to effect a desired pattern of axial and rotational movement of the tool. One method includes rotating the first threading in a first rotational direction, and simultaneously, rotating the second threading in a second rotational direction opposite the first direction.
