supports our customers with information and suitable cutting conditions for each work material by selecting the optimum indexable insert together with a suitable tool life expectancy.LABEL INDICATION
TOOL LIFE
Cutting speed affects tool life. Mitsubishi's suggests cutting speeds for 15─90 minute tool life and is based on Taylor's equation (Relationship for tool grade, cutting conditions and tool life). When a different tool is required, obtain the coefficient values from the charts below. Multiply the coefficient values by the cutting speed to calculate a new cutting speed.

- (ex.)
- Medium cutting of steel
The 1st recommendation : UE6110
Indexable inserts : CNMG120408-MA
Recommended cutting speed: vc=325m/min
(Tool life : 15min.)
325×0.82
267m/minHARDNESS OF THE WORK MATERIAL
Hardness of the work material also affects tool life. Mitsubishi's suggests cutting speed variations when material hardness differs. Obtain the suitable coefficient value for each type of work material from the chart below. Multiply the coefficient value by the recommended cutting speed of the grade used to calculate a new cutting speed.
