English to French Tech/Engineering Patents drilling apparatus

the drill head (1) or bit vibrates as a consequence of direct or indirect carrying of or hammering of, or both, the drill head (l)or bit by the first assembly(s) ( or 6) or the second assembly(s) (5 or 6), or both.

carrying =support? je pense que c'est dans le sens de porter

the spindle carrying a hammer and being rotatable under appropriate inputs to cause a vibrating and rotating spindle output to the left.
the second rotatable member carries arrays which interact with arrays 6 carried by the first rotatable member.

the magnetic arrays 27 of the first rotatable member 23 interact with the magnetic arrays 28 of the second rotatable member 26 thus to cause the central shaft at 22 to hammer back and forth on regions 24 and 25 of the second rotatable member and/or, by relativity of axial movement between members 23 and 26, to derive a hammering affect which carries directly to the cutting head 21.
