ABSTRACT:
The apparatus, especially a grinding machine, comprises a frame (14) on which two working planes (A, B) are used, at least two oscillating elements (11, 12) disposed on one of the planes and each including at least one tool device (15, 16), at least one further tool device disposed on the other plane, and at least one means for generating oscillating motion (20) whereby a reciprocating movement can be generated at the level of each of the oscillating elements, so that the resultant of the vectors representing the dynamic forces associated with the movement of each of the oscillating elements is substantially equal to zero. There is then little or no induced vibration.
