Claim:
1. A grip device for locking metallic bodies destined for machining by means of machine tools, comprising: at least one accommodation body adapted to engage with a bottom of a cylindrical container, said at least one accommodation body adapted to be supported by a movable table; an annular membrane extending from said at least one accommodation body, said annular membrane having at least one deformable portion that can be deformed in a radial direction inward to allow said at least one accommodation body to engage with said bottom of said cylindrical container, said annular membrane having a first side and a second side opposite said first side, said at least one deformable portion being between said first side and said second side; a first presser body coupled to said first side of said annular membrane and a second presser body coupled to said second side of said annular membrane; and a plurality of elastic loading bodies adapted to abut against a first abutment ring and a second abutment ring, wherein said first and second abutment rings are integral with said first and second presser bodies, respectively; wherein said at least one accommodation body is adapted such that relative movement of said movable table is adapted to move said first and second presser bodies closer together and further apart, to cause a transition of said annular membrane between a locking position and a release position, respectively.
