EPMVL end mill is designed unequal teeth spacing and variable leads. With serial change of teeth spacing, it effectively suppresses periodic stress and subtle vibration during cutting. Its variable leads alter the abnormal condition such as large resistance, big noise and processing surface slant under vibration cutting.
On low HP machines, STC LP9 EPMVL end mill can performs high machining efficiency and tool life in 1D groove processing. For finishing process, it can also achieve better surface and vertical precision than standard endmills do.
For carbon steel, alloy steel and medium hardness steel:
Characteristics: Adopts unequal teeth spacing and variable leads design, able to suppress vibration noise and reduce resistance during machining, to obtain excellent processed surface and vertical precision. Special
SC nanocomposite coating (hardness: HV4300) promotes machining hardness to HRC62.
Diameter (mm) Tolerance: below 12 -0.005 〜 -0.03
Diameter(mm) Tolerance: above 12 -0.005 〜 -0.04
Radius Tolerance (Corner R Tolerance): +0.02R 〜 -0.01R
For stainless steel, titanium alloy and nickel alloy:
Characteristics: Unequal teeth spacing and variable leads design can suppress vibration noise and reduce resistance during machining. Special cutting edge is sharp and cuttings inadhesive. SG coating (HV4300)
can largely elevate cutting efficiency and tool life on stainless steel and titanium alloy machining.
