摘要： Provided is a tap holder configured so that compression-side elastic characteristics and tension-side elastic characteristics are different from each other with utilization of an elastic member for absorbing synchronization error in rotation and feeding of a spindle of a machine tool. The tap holder includes a chuck 20 for holding a tap P, and a holder body 10 for holding the chuck 20 so that the chuck 20 is movable along a rotational axis X and rotatable in synchronism with the chuck 20. The tap holder further includes elastically deforming members 31, 32, 33 provided in a tension direction and a compression direction, respectively and deformable between the chuck 20 and the holder body 10 when a tension force or a compression force is applied to the tap P along the direction of the rotational axis X, and a deformation reducing mechanism 29 for the elastically deforming members 31, 32, 33 such that a deformation amount along the rotational axis X generated in at least one elastically deforming member 31, 32 of the elastically deforming members 31, 32, 33 disposed respectively in the tension direction and the compression direction is smaller than an amount of displacement of the chuck 20 along the rotational axis X.

摘要： An interchangeable machine tool holder unit for use in a machining apparatus for the support of a machining element, for example, a cutting bit, which includes an elongated rotary body adapted to be driven in one direction about the longitudinal axis thereof, a tool holder supported in end-to-end fashion by the rotary body for movement in a direction radially of the rotary body, an axially displaceable member axially displaceably carried inside the rotary body, and an indexing mechanism for causing the axially displaceable member to move in the axial direction each time the rotary body undergoes one complete rotation to permit the tool holder to move in the radial direction. During the continued rotation of the rotary body in one direction, the displaceable member is axially moved in response to each complete rotation of the rotary body, and the movement of the displaceable member results in a radial shift of the tool holder to permit the cutting bit to effect counterboring, drilling or cutting of a workpiece.
