Note 1) When high machining accuracy is needed, or work material becomes chipped, we recommend lowering feed rate. Note 2) Use a milling machine dedicated for graphite. Note 3) If rigidity of machine or work materials installation is very low, or chattering and noise are generated, reduce revolution and feed rate proportionately. I257
