Definitions

  • a sanding machine comprising at least one sanding unit, which in its turn comprises at least one sanding pad according to any one of the preceding claims, each operated in rotation around a respective axis, said at least one sanding pad being intended for sanding surfaces made of wood, plastic, metal and the like.
  • Each sanding pad P essentially comprises a rotating body 1, an abrasive disc 2, and an annular element 3.
  • Said guiding means 32 provide a first position of said pin 17 on the same, to hold said annular element 3 in said unlocking position of said abrasive disc 2, and a second position of said pin 17, to release said annular element 3 in the position wherein said abrasive disc 2 is clamped due to the action of said elastic means 7. More particularly, referring to figure 3 , said guiding means 32 are made as a slot obtained on said internal surface 31 of said annular element 3, having a first 321 and a second 322 portion, positioned at different heights, so as to hold said annular element 3 in a different position when the pin 17 is housed in one of said portions of said slot.
  • the operator can remove the worn abrasive disc 2 and replace it with a new abrasive disc 2.
  • said relief 17, inside said guiding means 32 passes from said second unlocking position of the abrasive disc 2, to said second position, for locking the abrasive disc 2; while said spring 7 passes from compressed to elongated and the abrasive disc 2 remains so tight, between the first toothed portion 33 of said annular element 3 and the second toothed portion 124 of said main plate 12, thanks to the action of the spring 7
