Turbine Nozzle Model
Alloy718
MSXH440R / Power Radius End Mill
Work Size: Φ80×35(mm)
Material: Alloy718
(Equivalent to Inconel®718)
Cutting time: 1 hr 45 min
Unequal helix angle and flute spacing reduce chattering.
Large tip pocket adopted to realize high efficient milling to tough materials.
Tool
MSXH440R
•Improved designs of unequal helix angle and flute spacing to suppress from chattering to realize stable milling progression.
•Original spiral design at corner radius flutes improves cutting edge performance!
•Designed for high rigidity to suppress corner radius flute breakage even on rough milling stresses.
•Adopted Mugen Coating Premium to suppress from chattering to realize stable milling progression, improved heat resistance and cutting edge strength to protect from milling heat influence.
