摘要： A clamping apparatus for clamping the attachment for mounting the tool to the part to which the tool is mounted of the machine tools is disclosed. The attachment for mounting the tool is coaxially provided with the taper extruding shafts which are fitted into the taper hole of the part to which the tool is mounted and the holding shafts the peripheral part on the tip end of which has the holding claw being laterally extruded. The clamping cylindrical article equipped with the claw to be held whose engagement with the holding claw, introduced by the fixed angular amount of forward rotation of the clamping cylindrical article, allows the attachment for mounting the tool to be prevented from coming off, is disposed in the part to which the tool is mounted such that the clamping cylindrical article may be rotatable and axially movable. The rotational driving means with the forcing mechanism which rotates forward the clamping cylindrical article to be inwardly drawn in and/or rotates backward the same to be pushed to come out is provided.

摘要： A chuck allowing to mount a cutting tool on the spindle of a machine tool. The chuck includes an ahead projecting chuck cylinder provided on the one side of a chuck body in a mated fashion to each other, and a tightening rotary sleeve mounted through needle rollers outside the chuck sleeve, in addition, slits configured in the top end part of the chuck cylinder, wherein the rotation of the tightening rotary sleeve causes the slits to contract so that a cutting tool is gripped.

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： A vibration damping mechanism allows increase of an absorption amount of vibration energy, with less possibilities of increase in the manufacture cost of a vibration damping weight and of reduction in the strength of a shaft section. Within a cylindrical hollow portion formed inside the shaft section, there are accommodated a plurality of weight members divided from each other along the circumferential direction about the axis of the hollow portion. An urging member is provided for urging the weight members toward the axis such that dividing faces of adjacent weight members are brought into surface contact with each other.

摘要： An insert includes a rake angle set corresponding to the hardness of a material to be cut and that can suppress an increase in the material cost even when the strength of a cut edge section is increased. The insert has a polygonal shape and includes a cutting edge portion on at least one side of the polygonal shape. The cutting edge portion includes a rake face having a convex formed on one of opposite surfaces in the thickness direction, a flank face having a concave formed on a surface intersecting with the one surface in the thickness direction and a concave cutting edge that is formed between the rake face and the flank face.

摘要： An automatic tool-replacement apparatus including the main body of a machine tool on which a plurality of tools can be dismountably mounted. The tools are selectively held by an automatic tool-replacement arm and are mounted on or dismounted from the main body. The arm has a plurality of holding portions for holding the tools. Therefore, a plurality of tools can be mounted on or dismounted from the main body of the machine tool by one-time operation of a single arm. Each holding portion has a pawl for preventing disengagement of the tool positioned therein, this pawl being able to advance toward and retract away from the holding portion.
