Abstract

Disclosed is a super finisher machine to 1) polish freshly extruded aluminum photoconductive (OPC) drums to remove tiny surface irregularities, and 2) to remove OPC coated layers from aluminum drums to enable recycling of the aluminum drum substrates. A matte surface is produced which is preferred for laser printer applications since this eliminates the known plywood defect.

Disclosed is a super finisher machine to 1) polish freshly extruded aluminum photoconductive (OPC) drums to remove tiny surface irregularities, and 2) to remove OPC coated layers from aluminum drums to enable recycling of the aluminum drum substrates. A matte surface is produced which is preferred for laser printer applications since this eliminates the known plywood defect.

A superfinisher is a surface finishing process that uses abrasive wet finishing belts to produce an irregular highly diffused surface. This is a continuous drum feed process with continuous wet belts in series doing the surface finishing. The drums but end to end as they move through the process.

A superfinisher has multiple finishing belts, for example, three, which can remove material in the range of 10-40 microns. The first belt can be aggressive to remove the coating, the second less aggressive to finish up the coating removal, the last finishing belt is used to produce the desired surface morphology for the application. For example, the surface of substrate used for laser printing has a diffused surface and is presently different than that used for light lens machines. This reclaim process and machine could also be utilized on rejected uncoated or solvent/chemical...
