Air Current Generated By Cutter Patents (Class 29/DIG82)
  • Patent number: 4909681
    Abstract: A router for separating individual component mounted printed circuit boards from a panel consists of a routing machine and programmed control console which controls movement of a spindle assemblage in the routing machine in the Z direction and a table carrying the panel in the X and Y directions. A pressure foot housing, which encompasses the rotatable spindle nose of the spindle assemblage, has a rectangular brush at its end which presses against the panel to be cut by a routing bit. A vacuum exhaust system is attached to an angled port in the housing. The geometry of the housing area causes a vortex to be produced which sucks up all debris cut by the routing bit to the port to be exhausted from the housing.
