仿形粗加工用。可用于从粗加工到半精加工等加工范围。最适合用于模具的仿形粗加工。柄径比刀头直径大,所以刚性好。由
于切削面具有大的切削接触表面积,所以刀刃的强度高,适合用于加工高硬度材质和钛合金。虽然是粗加工但是可保证表面粗
糙度可达 Ra2.5 到 Ra4.9(um)
For rough copying. It is available for roughing and semi finishing, but especially suitable for rough copying of mold. Shank diameter is larger than the
cutting diameter and it is highly rigid. Due to the strong cutting edge with large flat surface, it is suitable for hardened materials and titanium alloy.
It can provide the good surface roughness of 2.5 to 4.9 (μmRa).
