Description
Version:
With advanced DLC sp2 coating. For the highest demands regarding performance and precision in aluminium materials. Extremely tight tolerances ensure maximum accuracy. Double relief ground with 2 hollow-ground chamfers. Recess angle α = 16°.
Tolerances:
Tolerances:
- Neck ⌀: D1 = 0 / -0.01 mm.
Note:
At greater tool overhang lengths, use a reduced value for ap!
Values for:
slots milled from solid: ap = 0.25×D×ap corr
side milling: ap = 0.5×D×ap corr
To calculate the feed rate vf please use the actual speed of the machine (the maximum possible speed)!
e.g: vf = 18000 [rpm]× fz [mm/Z]× z
Values for:
slots milled from solid: ap = 0.25×D×ap corr
side milling: ap = 0.5×D×ap corr
To calculate the feed rate vf please use the actual speed of the machine (the maximum possible speed)!
e.g: vf = 18000 [rpm]× fz [mm/Z]× z
