Useing Geman micro grain material SMG 0.5 um.
helix  angle 35° blade design, cutting impendence moderate, good adaptablilityfor the working piece material and hardness, widely applied in moulds and products copy and finished machining, high quality and reasonable price.
with Aluminum, titanium nanometer coating; endurance 10-20% higher than regular Aluminum, titanium.
Adapt cutting material:
S50C, 40cR, 42CrMO, 20Cr, Cr12, H13, NAK80, 718etc. carbon steel, alloy steel, cast iron, die steel.
Adapt process hardness:
adapt machining haardness range HRC32-HRC45, end mill cutting efficiency and life behavior best.
General cutting parameter:
cutting speed: Vc=130m(100-180m)/mln
cutting depth: ap=1/3D(1/8-1/2D)
cutting length: ae=1/2D(1/4-1D)
signle flute feedrate: fz=0.1mm(0.02-0.2)
different working material and hardness, cutting parameter is different.
