Benching is the process of preparing the work piece for actual polishing. AII benchwork must be completed before you begin to polish. Benching can be as little as installing a radius or as involved as discing, grinding, and blending converging surfaces and then smoothing with flap wheels or coarse emery. When extensive benching is required deep cutter marks and stepped surfaces should be worked first, then the radii should be installed or refined. A polisher will always work from detail to open areas. Start benching with coarse perishables, progressing to finer.
