Abstract:
A method of providing bi-directional linear polishing comprising the steps of:providing a polishing belt on a support mechanism between a supply area and a receive area, the polishing belt having a first end and a second end and a polishing side and a backside, such that the first end initially comes off the supply area and is connected to the receive area and the second end remains connected to the supply area; polishing by bi-directionally linearly moving a portion of the polishing belt within a polishing area; advancing the polishing belt to obtain another portion that will be used for polishing, wherein the step of advancing advances the polishing belt over a support mechanism such that the polishing side of the polishing belt is not degraded by the support mechanism; polishing by bi-directionally linearly moving the another portion of the polishing belt; and repeating the steps of advancing and polishing using another portion.
