Explanation of the cutting parameters table
In the following pages you will find the table on the right under
the tools. The cutting speed Vc (m/min) is given under the respective
serial numbers.
In addition, we have given the following feed rates:
Drilling = mm / revolution
Countersinking / counterboring = mm / revolution
Milling / cutting = mm / tooth
Reaming = mm / revolution
Turning = mm / revolution
P = Steel
M = VA
K = Cast iron
NE = Non-ferrous metals
H = Hardened materials
S = Special-purpose alloys
Values printed in bold type = first time use
Note:
All cutting paramters are guideline values and have to adjusted to the individual situation. To this end, it is especially necessary to
ensure adequate cooling, stable clamping of the workpiece and sufficient machine power.
