A chuck device includes a chuck main body, an exchange member, an axial direction regulating mechanism, and a circumferential direction regulating mechanism. The axial direction regulating mechanism has a circumferential groove section, which extends in the circumferential direction, that is recessed into one of the chuck main body and the exchange member and a radially protruding section, which is able to protrude in the radial direction, that is disposed in the other of the chuck main body and the exchange member. The circumferential direction regulating mechanism has an axially recessed section, which is recessed in the axial direction, that is disposed in one of the chuck main body and the exchange member and an axially protruding section, which is able to protrude in the axial direction, that is disposed in the other of the chuck main body and the exchange member.

Provided is a tool magazine capable of automatically exchanging a tool holder between the tool magazine and a spindle. A tool magazine includes: a magazine body; an operation lever disposed to the magazine body, the operation lever reciprocable in the axial direction of the spindle with the operation sleeve in a supportable manner, the operation lever including, an operation sleeve receiving hole configured to receive the operation lever, and a hook portion disposed in the operation sleeve receiving hole to be hooked in the receiving portion, an operation lever guide configured to guide the operation lever in the axial direction of the spindle; and an operation elastic body configured to urge the operation lever toward a basal end of the spindle against an elastic force of the holder elastic body.

A positioning cutter/collet assembly has a cutter/collet and a magnetic attracting position key. The cutter/collet has a cutter/collet key seat recessed in an external annular surface thereof. The magnetic attracting position key is mounted on and magnetically attracts the cutter/collet key seat. The magnetic attracting position key has a body having a protruding rod and a magnetic attracting portion combined with the body and magnetically attracting the cutter/collet to prevent the magnetic attracting position key from separating from the cutter/collet.

A collet chuck for clamping a tool shank, comprising a chuck body, a collet and a multi-part clamping nut consisting of a clamping ring and a threaded section rotatably connected to each other via rolling elements, otherwise connected in an interlocking manner, wherein the clamping ring and the collet comprise interlocking coupling elements designed such that the collet can be inserted into the collet housing through the central opening, facing away from the chuck body, of the clamping ring held on the chuck body, while the coupling elements move past each other, and then the coupling elements can be brought into engagement with each other by rotating the clamping ring relative to the collet, so that the clamping ring can transmit the forces applied to it by the threaded section during tightening to the collet via the coupling element and can drive the collet into the chuck body.

A rotating tool includes a circumferential surface formed with a tool anchorage arrangement. The tool anchorage arrangement follows a stepped path. The tool anchorage arrangement includes an entry recess and, subsequent thereto, a radial recess and, subsequent thereto, an axial recess. Additional radial and axial recesses may be alternated to increase the number of steps, thereby extending the length of the stepped path.

A robot quick-release assembly has a first joint member and a robot component mounted thereon, the first joint member has a first coupler and a second joint member, a robot arm mounted thereon has a second coupler, a clamp, and a locking collar. The first coupler can be coaxially aligned with the second coupler and pressed into the second joint member, and detachably connected to the second joint member. The first mechanical coupler is detachably connected to the second mechanical coupler for transferring power across the quick-release assembly. The robot component can receive an additional electrical connector, the additional electrical connector supplying power to the robot component. The quick-release assembly coupling assembly further exerts large forces with the application of a relatively small torque to the locking collar by applying a two stage wedge engagement and can further include a sequencing system.
