A machine tool includes a lower tool post for holding a cutting tool, a tool main spindle for holding a cutting tool, a storage unit capable of storing the cutting tool, an exchange mechanism for exchanging the cutting tools between the tool main spindle and the storage unit, an inside robot for exchanging the cutting tools between the lower tool post and the tool main spindle, and a controller. The controller performs control such that the cutting tools are exchanged between the lower tool post and the storage unit via the inside robot, the tool main spindle, and the exchange mechanism.

A spar structure can connect a moveable component to an aircraft. The structure is formed from a single continuous body of material defining a plurality of attachment/actuation brackets and a pair of continuous hinge lines extending through the body.

An attachment for converting a CNC milling machine to a CNC wire saw machine. The attachment may include a gantry that may be coupled with a respective gantry of the CNC milling machine, a carriage that may be attached to and moveable with a respective carriage of the CNC milling machine. A drive pulley of the system may be coupled with and driven by a spindle of the CNC milling machine. The drive pully may drive a wire saw through an assembly of idler pulleys. A wire tension mechanism may keep the wire fully stretched. The wire tension mechanism may include a curved guide rail mounted on the gantry and a vertical guide rail mounted on the carriage. A slider that slides vertically on the vertical guide rail and follows the curved guide rail may house a tension wheel that may keep the wire at a fully stretched state.

A complex machine tool for cylindrical workpieces has a bed, a headstock assembly, at least one supporting assembly, and at least one machining assembly. The bed has three tracks being respectively a first track, a second track, a third track arranged in order. Each one of the three tracks defines a respective guiding direction, and the three guiding directions of the three tracks are mutually parallel. The headstock assembly is connected to the bed, and is located near one of two ends of the second track. The at least one supporting assembly is mounted on one of the three tracks and is used for supporting the cylindrical workpiece. The at least one machining assembly is mounted on one of the three tracks, is slidable along the track, and is located on a position at a spaced interval from the at least one supporting assembly.

A multi-purpose precision machine tool is provided, which has main structures including a machine tool body, and a first workpiece fixing mechanism, a second workpiece fixing mechanism, and a tool mechanism provided on the machine tool body. The first workpiece fixing mechanism and the second workpiece fixing mechanism respectively include an internally expanding clamp and a soft-jaw chuck for clamping a workpiece, so as to not only drive the workpiece to rotate, and but also drive the workpiece to perform horizontal and vertical linear displacement. Therefore, the internally expanding clamp can first clamp the workpiece to machine one end of the workpiece, and then the soft-jaw chuck clamps the other end of the workpiece to machine the other end of the workpiece.
