The JY Diamond Edge Polisher removes saw marks and produces a clear, polished edge on acrylic parts, all in a single pass through the machine. Single or multiple work pieces are fed by two constant - tension gear driven belt assemblies across a special diamond cutter, mounted on a high speed, super precise 22,000 rpm spindle. The feed rate is infinitely variable from 0 to 10 ft per minute, via a DC speed control. The feed belt assemblies can swing out to permit easy access to the cutter and are completely protected by safety guards. A complete set of tools for set-up, adjustment and operation is furnished with each machine, along with a depth indicator and base for setting cutter height.
