ABSTRACT:
A tubular workpiece notching machine usable for general grinding operations has a worktable (1) whose base plate (10) is pivotally mounted to the frame (6) of the notching machine around a pivotal orthogonal axis (Y—Y) in such a manner that the worktable (1) is movable from a first working position in which the machine vice (2) co-operates with the shaping pulley (3) in recessing ends of tubular workpiece by grinding, to a second working position in which the shaping pulley (3) is used for generally grinding a workpiece. Connecting elements are provided for removably anchoring the base plate (10) of the worktable (1) to the frame (6) in the first working position.
