A vibration machine of volumetric working contains a reactive mass being symmetrical relative to the horizontal plane, which is connected by vibration-isolating rods with the frame, vertically located elastic rod, jacket, first circular electromagnetic vibration exciter. It also contains symmetrically located relative to the same horizontal plane first and second active masses, second and third circular electromagnetic vibration exciters, first and second flat elastic systems, first and second torus-shaped containers, first and second ring-shaped intermediate masses. Elastic rod is rigidly fixed by its ends in the first and second active masses, and it is rigidly fixed by middle part in the reactive mass. To the first and to the second active masses by their center sections respectively the first and the second flat elastic systems are fastened, on periphery of which the first and the second torus-shaped containers are fastened respectively. The first and the second active masses are absolutely rigidly connected together by absolutely rigid jacket in the form of a hollow cylinder. The armatures of the second and third circular electromagnetic vibration exciters form the first and the second ring-shaped intermediate masses respectively, which are rigidly fastened respectively to the first and second flat elastic systems and located coaxially respectively between the first toroid-shaped container and the place of fastening the first flat elastic system and between the second toroid-shaped container and the place of fastening the second flat elastic system. Cores with the coils of all three circular electromagnetic vibration exciter are located in the reactive mass. It contains third intermediate mass in the form of a hollow cylinder, which is located vertically and symmetrically relative to the horizontal plane of symmetry and fastened to the upper and lower halves of elastic rod respectively between the places of fastening upper end of elastic rod and its middle part and lower end of elastic rod and its middle part. To the third intermediate mass in the center section of the hollow cylinder the armatures of the first circular electromagnetic vibration exciter are fastened.
