Abstract: 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.

Abstract: An automatic lathe includes a front main spindle holding a workpiece and a turret including a peripheral surface, the peripheral surface being divided into a plurality of turret surfaces, tools being mounted on the turret surfaces, the turret machining the workpiece with any of the tools selected by turning about a Z axis, wherein at least one turret surface of the turret surfaces of the turret has a distance from the Z axis shorter than that of the other turret surfaces.

Abstract: A tool for training and evaluating a motion control function through vision while the direction and range of motion is restricted by the tool, and a method for using the same, and to improve storage convenience. A training tool is configured such that lattices are formed by using a belt having a width (S) in a vertical direction and a horizontal direction to be spread out and placed on the floor or the ground. The training tool is formed from a plurality of lattices arranged in vertical and horizontal squares, and the length of a lattice in any one of the vertical and horizontal columns is the length of (L-S) that is shorter by the width of the belt than the length (L) of each of lattices in other columns, whereby the tool is foldable such that the tool is integrated to overlap with one lattice.
