than specified.
h. Chromium carbide grain growth inhibitor only.
2. All the tools of production, coatings are used in Germany,
Switzerland, processing equipment;
Coating:
Universal High Performance Coating AlCrSiN
Characteristics and Function
1,Productivity increase due to significantly higher cutting speed
and feed for applications in a wide range of
materials.Sighificantly enhanced productivity.
2,Particular design of structure brings good balance between
toughness,thermo-shock stability and residual stress.
Literal statement:
The structure of Iphone 8 is used 316L stainless steel. This
material is more difficult to cut than the 304 stainless steel.
Especially the suppliers of Apple Inc. use MIM processing of small
accessories, the previous endmills has been unable to meet their
needs. Our team has adopted special ultra-fine grain tungsten
carbide, special spiral angle, special cutting edge design and Nano
AlCrSinN, the product has a perfect sucess, and has won high praise
from FOXCNN and MiYa.
Features:
Suitable for rough milling, semi-finishing and finishing of
stainless steel (<280HB).
Design for the small depth/large width in face milling, large
depth/small width in side milling, less than 0.3D in shallow
slotting.
Water soluable or oil based are the best cooling methods.
