Walnut Shell Granulets are used in disc finishing machines during the dry grinding and dry finishing processes. You shuld add grinding or polishing pastes according to the process.They are used generally last polishing process. Wallnut shell granulates are prefered for jewellery polishşng as they do not harden the surfaces of the soft metals. Otec offers a various sizes of wallnut shell granulates.
