TURNING INSERTS MC6025 CNMG432MP CNMG120408-MP TOOL NAVI OUTLINE TOOL NAVI supports our customers with information and supplies suitable cutting conditions for each work material by selecting optimal indexable insert together with the optional tool.

Some materials include elements other than this. PMKS • • • VB=0.3 mm unstable choose the tool life feed rate. H     • • • VB=0.1 mm TOOL LIFE Cutting speed has a large affect on tool life. TOOL NAVI is based on Taylor's equation (relationship vc x Tn=C between tool grade, cutting conditions, and tool life). Therefore, performance speed and tool life is found for each work material. When the customer requires different tool life, obtain coefficient values of the grade you use from the charts below. Multiply the coefficient values by the cutting speed to calculate the new cutting speed. P Grade (Steel) cutting speed coefficient values. K Grade (Cast lron) cutting speed coefficient values.

Mitsubishi’s TOOL NAVI suggests cutting speed variations when hardness of the work material differs. Obtain the suitable coefficient value for each work material from the chart below. Multiply the coefficient value by the recommended cutting speed of the grade you use to calculate the new cutting speed.
