Patent attributes
A vibrating lap polishing system for flat items, comprising a polish pan with flexible bottom mounted on a base having three or more round-head bolts of equal height extending vertically above the base surface and positioned at one hundred twenty degree spacing on a circle about the base center; a center bolt attached to and extending below the pan center into a nut rotated by horizontally positioned gears, a center gear which rotates the nut and an outer meshed gear available from the outside work area to raise and lower the workpiece during operation. Means, which put no holes in the polish pan, are provided to pull the polish pan down onto the round-head bolts which create raised areas in the flexible pan-bottom. A flat-bottomed multi-item workpiece is circulated and rotated in an unsynchronized manner over the raised areas which creates a complete polish of the workpiece after sufficient cycles.
