Portable modular deburring machine
First Claim
1. An abrasive machine suitable fling operations comprising a rotatable hub having an axial axis extending between a first end and a second end and an abrasive filament formed and secured against said rotatable hub and said rotatable hub mounted on a support, a rotating means for rotating said rotatable hub in a predetermined direction about a hub rotation axis that is coincident with said axial axis of said rotatable hub and supprt rotating means for rotation of said support in a predetermined direction about a support, rotation axis, wherein said hub rotation axis is perpendicular to and coplanar with said support rotation axis and wherein said support rotation axis crosses said hub rotation axis at a point along said axial axis of said rotatable hub at a position between said first end and said second end of said rotatable hub.

Abstract
An abrasive deburring machine comprised of a plurality of individually controlled abrasive modules, each having a rotatable drum type brush with flexible bristles, the drum is mounted on a rotatable support with axis of rotation generally perpendicular to the rotational axis of the drum. Each support with brush and support drive are mounted inside of a housing therefore creating a module. Plurality of such modules can be combined in a desired configuration to form a deburring machine or finishing/polishing machine tailored to a specific geometry of the work piece or part to be deburred, finished or polished. Each drum and drum support, including its axial angular position are controlled independently, which for a pre-programmed movement of all brushes in order to conform to a complex shape of the part to be deburred, optimize the process of deburring and maximize the durability of abrasive brushes. The drum type brush is preferably made of polystyrene foam with helical groove along its outer shape containing a continuous abrasive filament secured inside the groove and having bristle or strap like abrasive extremities. The invention includes a variety of modes of use being mostly applicable for deburring and finishing operations in Aerospace sector as well as in finishing operations in other metal, plastic and woodworking industries.
