For aluminum wrought alloys
In the machining of long-chipping aluminum, it is absolutely necessary to provide chip transport in an axial direction. In addition to the large rake angle, these tools are made with a reduced number of flutes so that there is even more room for the chips. This helps to avoid clogging of the flutes.
GLT-8 Coating - Diamond-like, amorphous carbon coating
- In a PVD process a coating thickness of 1-2 μm can be realized. The hardness is approx. 2500 HV. This mono-layer coating is an excellent choice for the machining of non-ferrous metals and aluminum with a low silicon content (< 9% Si). Thanks to the low friction, material adhesion is drastically reduced.
