摘要： The invention relates to a machine for the gear cutting machining of workpieces, in particular a gear shaping machine, comprising a spindle for holding a machining tool, and a drive by means of which the spindle can be rotationally driven about its spindle axis, and further comprising an arrangement. When said arrangement is actuated, a spindle rotation caused by the drive changes the axial relative position with respect to the spindle axis.

摘要： An oscillating power tool includes a drive motor producing rotary motion and an oscillating mechanism for converting the motor rotary motion to an oscillatory side-to-side movement. The oscillating mechanism includes a fork having two arms and coupled to an output spindle and includes a bearing positioned between the two arms of the fork and coupled to the drive motor. The arrangement of the fork and the bearing isolate relative rotation and translation between the components of the tool while still imparting an oscillatory motion to the output spindle.

摘要： A tool changer for machine tools, the tool changer having at least one rotatable tool gripper, a supporting column for the tool gripper which can be lifted and lowered and rotated about a rotational axis, a mechanical cam gear for generating the lifting and rotating movements of the tool gripper, all driven by a drive motor connected to a cam barrel and intermediate gearing. The cam barrel has a tappet for the rotational drive of the tool gripper on its upper front and a cam curve or groove on its peripheral surface for the lifting movement of the tool gripper. The tappet drives a Maltese wheel supported on a shaft parallel to the rotational axis of the tool gripper. The Maltese wheel, the cam barrel, and the supporting column of the tool gripper are successively supported in a manner parallel to the axis.

摘要： An actuator for moving a tool is disclosed, comprising a housing in which a tappet carrying a tool holder is guided axially movable, wherein the tappet is movable by means of a fast drive, e.g. by a piezo drive or by a nanotube drive, which is biased against a restoring force and which is dampened by a dampening element. Herein the fast drive may at least partially be received within a recess of the tappet which leads to a very compact design, in particular in combination with a coaxial dampening element. For guiding the tappet in axial direction alternatively a roller guide may be used (FIG. 3).

摘要： A drill has a tubular outer housing and a tubular inner housing. The inner housing is movable between extended and retracted positions. A pneumatic motor with a chuck mounts to the inner housing. Air pressure is delivered to annular pistons to cause the inner housing to extend and retract. Also, an annular hydraulic chamber with a variable orifice bypass controls the rate of feed. A processor records the total number of holes being drilled as well as recording the time duration for each hole.
