Note 1) The cemented carbide in the above mentioned cutting conditions table is based on CIS standard VM-40(90HRA). Note 2) Air blow or dry processing is recommended with cemented carbide processing. *Note: Using coolants or oil mists may decrease tool longevity. Note 3) The use of a water soluble cutting oil is recommended with the processing of hard brittle materials other than the cemented carbide mentioned in the above table. Be sure to refuel the oil and eliminate any chip discharge that adheres to the tool. Note 4) Cutting conditions may need adjustments depending on the type of work material. Note 5) Reduce the rotation speed and feed rate shown in the above table at a similar ratio when no rigidity in the machinery or work mounting and occurrence of chatter or abnormal sound. Note 6) Implementation of special countermeasures is recommended since fine chip discharge may enter gaps in the processing machinery. I275
