Definitions

  • the invention relates to an apparatus for milling, according to the preamble of claim 1.
  • Such an apparatus is disclosed by DE 2 503 830 .
  • a laminar edge-finishing element can be applied to one or more sides of panels made of wood or composite wood-based material or the like.
  • the edge element is milled in such a manner as to round and/or chamfer and/or eliminate, the sharp rims of the edge element.
  • An apparatus for milling an edge element of a panel comprising a milling unit that has a miller that is arranged for removing from the edge element the excess of material, and a rotation device arranged for rotating the miller.
  • the miller includes cutting elements, which have a determined cutting profile and cut the edge element on the base of the cutting profile thereof, i.e. the cutting elements cut from the edge element, and thus also from the panel, parts of the rim of the edge element in such a manner that the profile of the rim corresponds to the cutting profile.
  • the apparatus further comprises a further milling unit that has a further miller which is also arranged for removing from the edge element the excess of material, the aforesaid rotation device also rotating the further miller.
  • the further miller includes further cutting elements, which have a determined further cutting profile and cut the edge element on the base of the further cutting profile thereof, i.e. the cutting elements cut from the edge element, and thus also from the panel, parts of the rim of the edge element in such a manner that the profile of the rim corresponds to the further cutting profile.
  • the aforesaid rotation device includes a shaft that is rotatable around a rotation axis, on which the milling unit and the further milling unit are mounted coaxially.
  • the milling unit and the further milling unit are movable in relation to one another along a movement direction, which is parallel to and coincides with the aforesaid rotation axis, between a first operating configuration, in which the milling unit interacts with the edge element and the further milling unit does not interact with the edge element, and a second operating configuration, in which the further milling unit interacts with the edge element and the milling unit does not interact with the edge element.
  • a conical surface and a further conical surface are made respectively, the conical surface being arranged for interacting in a shapingly coupled manner with the further conical surface to guide the milling unit and the further milling unit between the first operating configuration and the second operating configuration.
  • the conical surface and the further conical surface enable the further milling unit to be centred, i.e. the further milling unit to be correctly positioned.
  • a drawback of this apparatus is that, in use, it has frequent centring problems.
  • centring problems are due to the deposit on the aforesaid conical surface, during the movement of the milling units between the first operating configuration and the second operating configuration, of parts removed from the edge element and/or of dust that penetrates, during this movement, an internal zone of the apparatus defined between the milling unit and the further milling unit.
  • DE 2503830 and DE 2541259 disclose a milling tool especially for machining edges of workpieces, comprising two cutter halves, whose teeth or knife laterally overlap each other, and means for shifting the cutter halves axially against each other or from each other.
