The tool abrasion and edge grinding of combination.

摘要

"The tool abrasion and edge grinding of combination".The present invention relates to an abrasion tool that can be configured selectively to a random orbit or rotation movement without the need of a reversible motor.The tool uses two collars, each having half the desired displacement and half of the counterweight.In the case of rotation, the beads are rotated so that their balances and the displacements cancel itself and the edge is balanced and concentric.The plate is coupled to the sanding necklaces for maximum grinding. This allows raw grinding with minimal vibration.In the mode of random orbit, the necklace of rotation is rotated 180 198 ,In such a way that the counterweights are aligned on one side of the axis of rotation, and the displacements are combined on the opposite side of the axis.The two necklaces are spread amongst themselves, but not to the sanding plate.There are provided means for feeding water to the edge grinding, to assist in the completion of the materials that benefit from the wet grinding.
