    摘要: A tool drive unit for a turning device for machining workpieces has a tool holder driven in a displaceable manner along an infeed direction by a first linear motor and driven in a pendular/displaceable manner in a direction transverse to the infeed direction by a second linear motor. Both linear motors have a moving coil/piezo element. The turning device has a main infeed drive, which produces a primary infeed movement of a turning tool in an infeed direction, and has a main transverse drive which produces a primary transverse movement in a transverse direction transversely to the infeed direction. The turning device has a secondary transverse drive whose movements are oriented in the same direction as the main transverse drive, wherein the turning tool and the axis of rotation can be moved towards one another and away from one another by the superimposition of primary and secondary transverse movements.

    摘要: A cutting tool includes: a cutting part including a cutting edge having a linear shape; and a fitted part including a fixed section to which the cutting part is fixed, and a fitted part body to be fitted to a cutting device. The cutting edge is located perpendicularly to a virtual line passing through a central axis of the fitted part body, on a plane that is perpendicular to the central axis of the fitted part body. A center of the cutting edge in its longitudinal direction is located on the virtual line.

    摘要: An automatic lathe includes a main spindle that rotates a workpiece about a shaft center, a cutting tool that processes the workpiece, a feeder that moves the cutting tool, an input receiver that receives inputs regarding an eccentric distance and a radius, and a controller that controls the movement by the feeder such as to set a virtual circle having a radius of the distance, to set an offset virtual circle having a center at a position where a center of the virtual circle is offset from the shaft center of the workpiece in the radial direction of the workpiece by the radius, and to move the cutting tool along an circumference of the offset virtual circle in relation to a rotation of the workpiece by the main spindle. A hole is processed, which has the radius at a position away from the shaft center by the distance.

    摘要: A machine tool cuts a workpiece having an inclined or curved surface and includes a main spindle that holds and rotates the workpiece, a moving device that moves a cutting tool relative to the workpiece in a direction obtained by combining a Z direction parallel or substantially parallel with the axis of the main spindle, an X direction that is perpendicular or substantially perpendicular to the Z direction and determines the amount of cutting of the workpiece, and a Y direction perpendicular or substantially perpendicular to the Z direction and the X direction, and an angle setting mechanism that causes the direction of an edge of the cutting tool to match the inclined surface of the workpiece by inclining the direction of the edge with respect to the Z direction when seen from the Y direction in a state in which the direction of the edge is inclined with respect to the Z direction when seen from the X direction.

    摘要: A workpiece supporting assembly, having a body member with an internal workpiece channel and a plurality of body openings communicating with the internal workpiece channel, supports a workpiece within the workpiece channel so that end portions of the workpiece extend from the body openings. The body member has a plurality of arbors, each arbor having a longitudinal axis that is coincident with a datum axis of one of the extending workpiece portions. A turning machine grips one arbor at a time and rotates the body member about the selected longitudinal axis for machining the extended workpiece portion.
