Abstract: A method of generating twin lamellas in a metal body includes the steps of introducing the metal body into a chamber, filling the chamber with a cooling medium having a temperature that will enable generation of twin lamellas in the metal body upon deformation thereof, and deforming the metal body while the latter is surrounded by the cooling medium. The cooling medium surrounds the metal body upon deformation of the latter is in a gaseous state. The present disclosure also relates to a device for generating twin lamellas in the metal body, the device including a chamber, a chamber inlet connected to a cooling medium source, and a deformation device arranged to deform the metal body. The deformation device is positioned inside the chamber so that the metal body will be surrounded by the cooling medium in a gaseous state while being deformed by the deformation device.

Abstract: A clamping device for releasably holding a tool holder shank is formed with an engagement bore in a rear end, and includes a housing having a bore in a forward end for receiving the tool holder shank, a drawbar reciprocally movable inside the housing and which in a forward end is provided with engagement means arranged to engage with an engagement formation inside the engagement bore of the tool holder shank, and which is formed with a drawbar aperture extending through the drawbar in a transverse direction of the same, and a cam shaft extending through the drawbar aperture. The cam shaft includes three cam formations and more precisely first and second spaced apart cam formations, which are journalled in seating apertures in the housing on opposite sides of the drawbar, and an intermediate third cam formation located between the first and second cam formations and positioned within the aperture of the drawbar. The drawbar is insertable into the bore from the forward end.
