Description
Version:
With crystalline diamond sp3 coating. For the highest demands regarding performance and precision in fibre-reinforced composites, CRP, GRP, and graphite. Extremely tight tolerances ensure maximum accuracy. Double relief ground with 2 hollow-ground chamfers. Recess angle α = 16°.
Tolerances:
Tolerances:
- Corner radius: R1 = ±0.0025 mm
- Neck ⌀: D1 = 0 / -0.01 mm
Note:
At greater tool overhang lengths, use a reduced value for ap!
Values for:
copying: ap = 0.10×D×ap korr
side milling: ap = 0.20×D×ap korr
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
