Definitions

  • the present invention relates to a tool for planing a surface and to a planing milling machine, comprising such a tool.
  • classic machines such as boring machines and routers, which are generally static machines, in relation to which the material to be bored moves, and which include strawberries having the shape of a wick, or a bit, the milling end of which has a particular shape, a particular profile, which depends on the cut to be made.
  • milling machines by planing, which are mounted on a frame, provided with wheels in order to facilitate their movement on the surface to be planed, but, more generally, they are portable and hand-held.
  • Planing milling machines are usually used in the field of depollution of all types of supports, conventionally, the depollution of floors, walls or ceilings. They make it possible to remove polluted or contaminated material, by planing a flat surface of a support, in order to recover a support having a cleaned material. However, in the field of construction or rehabilitation of old buildings, they can also be used to remove surface layers of any material, a construction material for example, such as concrete, stone, wood , or to remove one or more layers of one or more coatings, resins, coatings, paints covering the material.
