A tooling exchange mechanism and a machine tool having the tooling exchange mechanism, in which a load applied to a turret is reduced when exchanging a tooling in the machine tool, are provided with a pressing member 210 of a tooling detachment unit 200 that presses the rear end of a tooling holding unit 100 to be able to release the retracted state of a tool holder Th of a tooling T by a tool holder holding portion 150 of the tooling holding unit 100, and a locking lever 220 of the tooling detachment unit 200 engageable with an engaging projection 112a formed on the rear end side of the tooling holding unit 100.

A retention knob tool. A tubular body is held in a tubular sleeve, and symmetrically formed around an axis. The tubular body also has an internal bore. Four locking ball retainer sockets are formed in the tubular body. A retention knob aperture is recessed within a top plate. Four balls are movably held in the ball retainer sockets. A tubular end stop is affixed to the tubular body rearward end. A drive tool cavity is recessed within the tubular body rearward end. The sleeve forward end includes a recessed circumferential portion bounded by a first thicker portion of the inside wall, where the first thicker portion bears against the balls when the tubular body is translated rearwardly not an inward lock position and the inward force is removed from the plurality of balls when the tubular body is extended forwardly into a released position.

A bit-removal assembly includes a first ring coupled to an output shaft for co-rotation therewith, a second ring supported on the lower retaining ring of the output shaft, a frusto-conical surface on at least one of the first or second rings, and a wedge positioned between the first and second rings and engaging with the frusto-conical surface. A collar defines a cam surface located radially outward of the wedge. The collar is movable between a locked position, in which the cam surface is engaged with the wedge to displace the wedge radially inward on the frusto-conical surface to separate the second ring from the first ring, and a released position, in which the cam surface is misaligned with the wedge to permit the wedge to move radially outward on the frusto-conical surface. A biasing member urges the collar towards the locked position.
