摘要:
A rotating chuck (10) includes a coolant groove arrangement (26) integrally along a shank-receiving bore (16) of the rotating chuck (10). The groove arrangement (26) defines a flow path in fluid communication with front and rear bore ends (20,22). The groove arrangement (26) includes one or more slanted groove portions (32) opening out to, and being inwardly inclined towards, a front chuck end (12) of the rotating chuck (10).

The invention relates to an interface composed of a first subassembly (20) and a second subassembly (90), wherein the first subassembly (20) has both a recess (30), which has at least one frustoconical portion (32), and also an abutment surface (24) that acts in the axial direction, and wherein the second subassembly (90) has at least one peg (100) which has both a frustoconical-shell-shaped portion (120) for butting against the frustoconical-shell-shaped portion (32) of the first subassembly (20), and also at least one abutment surface, acting in the axial direction, for making contact with the abutment surface (24) of the first subassembly (20). Arranged between the recess (30) and the peg (100) is a bayonet-type closure having at least one protrusion (106, 115) that is present on the peg (100). Arranged in the first subassembly (20) is a clamping element (60), the front end of which butts against one of the protrusions (106, 115) during clamping. The present invention provides an interface which ensures, for each tool change, easy handling together with high repeatability with regard to the position of the mutually contacting subassemblies.

Disclosed is a tool holder (100) using a shape memory alloy. The disclosed tool holder using the shape memory alloy, includes: a holder body (110) including: a coupling portion (111) at a rear side which is coupled to a chuck means; a clamping portion (113) at a front side which has a bore (113a) into which a shank portion (S) of a tool (T) is inserted, a plurality of slits (113b) formed on an external circumferential surface of the clamping portion, communicating with the bore, and arranged in a circumferential direction, and an external thread portion (113d) formed on a tip portion of the external circumferential surface; and a reinforcing portion (112) in which an axial shape of an external circumferential surface between the coupling portion and the clamping portion has any one shape of a tapered shape, a two-dimensional curved line shape, and a horizontal line shape; a shape memory alloy ring (120) which tightens or loosens the clamping portion in a radial direction of the axis while being heated or cooled in a state in which the shape memory alloy ring is fitted on the slits of the clamping portion; a spacer (130) which is interposed between the reinforcing portion of the clamping portion and the shape memory alloy ring; and a locking cap (140) which is thread-coupled to the external thread portion of the clamping portion by an internal thread (141) formed on an inner circumferential surface and prevents the shape memory alloy ring from being moved away.

摘要:
A method for manufacturing a crankshaft with a turning and broaching machine (1) is provided with a temporary setting process, a lifting process, a centering process, and a clamping process. An unprocessed crankshaft (W) is mounted on first and second temporary settings (32d, 42d) in the temporary setting process. A rear flange (210) is lifted by a first chuck jaws (32b) and a front flange (220) is lifted by a second chuck jaws (42b) in the lifting process. First and second centers (32c, 42c) are inserted into first and second center holes (210CH, 220CH) in the centering process.
