pressure during milling are to be eliminated to reduce failure. In difficult conditions
with adhesive related materials cleaning frequency may need to increase.
The cutting edges of the tool are intact. Dull or damaged cutting edges lead to
unfavorable milling results. Likewise, heavily worn running surfaces or copper deposits
in the holder can lead to errors. In case of doubt it is always advisable to replace the
part.
Re-sharpening of the blades is not recommended, especially if the cutting plate has
flakes, cracks or breaks.
The cutting properties of the tool change with each re-sharpening. The cutting ability
of the tool is determined by the clearance angle of the cutting edge and the protrusion
on the running surface in the holder.
When re-sharpening, coatings may be compromised, reducing life cycle.
