Patent ID: 6848982

Claim:
A tubular workpiece notching machine usable for general grinding operations, having on a frame ( 6 ) a pair of pulleys carrying an abrasive belt ( 5 ) travelling endlessly on them, and a worktable ( 1 ) holding up, over a base plate ( 10 ), a machine vice ( 2 ) adjustable in its angular position with respect to a shaping pulley ( 3 ) of said pair of pulleys, characterized in that: said base plate ( 10 ) of the worktable ( 1 ) is pivotally mounted in said frame ( 6 ) around a pivotal orthogonal axis (Y—Y) in such a manner that the worktable ( 1 ) is movable, by rotation around said pivotal axis, from a first working position in which the machine vice ( 2 ) co-operates with said 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 means are provided for removably anchoring said base plate ( 10 ) of the worktable ( 1 ) to the frame ( 6 ) in said first working position.
