The point of tool selection for milling aluminum
Q. What should we be careful about when processing aluminum alloys？
A. Please note that it is soft and highly malleable and viscous, so easy to adhere.
Q. Which ball end mill is suitable?
A. The characteristics required are :1.Sharp cutting edge that suppresses cutting resistance so as not to raise the cutting temperature.
2. Coating with low affinity with aluminum alloys.

Housing rib (Electrode) model milling
Model : DLCLB

Material : A7075 (Extra Super Duralumin)

The milling surface by DLCLB had no-adhesion and the smooth surface that reflects identifiable characters.
From the result, DLCLB is suitable for milling aluminum.

In roughing / semi-finishing, both the rake face and the relief face of DLCLB suppressed adhesion.
After 2hrs 40min of finishing, the tool wearing was small and the tool was still available.
