Grind master manufactures three head conveyor belt grinding machine. These grinding machines can be applied for deburring and finishing punched fine blanked, sintered, laser cut parts like clutch plates. The belt-grinding machine comprises 2 belt grinding heads and one planetary deburring head. The machines are available with working principles like first; belt grinding head remove heavy burrs with coarse grit belt; next, belt grinding head improves surface finish with finer grit belt; and last, planetary brushing head knocks off folded burr and all secondary burr. Planetary head uses four brushes and due to the planetary movements, the burr that gets folded because of one brush is knocked off from its root by next brush. This unique operation of the belt grinding machines also generates micro radiating on sharp corners and edges of the components. The machine is popular for deburring of flat components like clutch plates, sprockets, punched parts, blanked parts and sintered milled parts, etc.
