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