Except for that, \u00a0what kind of impact will the size of helical angle have on end milling cutters? Tool and edge angles are interrelated and impact for each other.

As we all know, there are two basic types of cutting edge shapes for end milling cutter: straight shape and helicalshape, among which the helicaltype is more widely applied because it can lead to faster, stabler, and more effective cutting than straight type. You can see the general 2 types of helicaledge in fig.1. Left helicaltype is mainly used for high precision milling, such as processing mobile phone keys , film switch panel, LCD panel, and acrylic lenses.
