PCT No. PCT/EP92/01449 Sec. 371 Date Jan. 14, 1994 Sec. 102(e) Date Jan. 14, 1994 PCT Filed Jun. 27, 1992 PCT Pub. No. WO93/02539 PCT Pub. Date Feb. 4, 1993.The machine tool has a frame (10) and in it, a cam gear with two pairs of cam tracks with complementary cam shapes. The tool actuation takes place by means of two levers (3a, 3b) which are hinged to the side on a clamping plate (8). Each of these levers has two rollers (4a, 6a; 4b, 6b) on one of its arms and these are coupled positively to one cam track pair each. The position of different cam tracks is matched in a certain way with the objective of reducing the frequency of disturbing vibrations.
