A tool clamping device having a tool holder holding a tool, said tool holder being designed for insertion into a socket of a tool carrier, in particular a lathe, has a tool quick-change system.

A lathe has a plurality of turret positions with at least one having a toolholder, a pair of blades projecting from one end of the toolholder with the toolholder structured to assume a first position with a first blade machining said workpiece which is rotating in a first direction and a second position with a second blade structured to assume a second position with the workpiece rotating in the other direction. The toolholder remains fixed during machining. Related methods and toolholders are disclosed.

A machine tool includes a spindle equipped with a workpiece gripping portion arranged so as to face an operator side, the spindle being configured to rotatably drive a workpiece gripped by the workpiece gripping portion, and a tool mount equipped with a rotary member supporting a plurality of tools in a rotatably indexable manner about an axis parallel to an axis of the spindle. The tool mount is arranged at a tool mount installation portion formed to be positioned on the operator side in a manner such that the rotary member faces a workpiece gripping portion side.

A vibration reducing device for a machine tool reduces vibration generated in a tool support body supporting a tool. The vibration reducing device includes an attenuation inducing member and a pressing and fitting mechanism. The attenuation inducing member is brought into contact with the tool support body so as to generate a frictional force in a direction in which it acts as a resistance to the vibration generated in the tool support body. The attenuation inducing member has a rigidity in a direction conforming to a contact surface between the attenuation inducing member and the tool support body, which rigidity is higher than that of the tool support body. The pressing and fitting mechanism fits the attenuation inducing member to the tool support body in a pressed condition.
