The outer edge and the bottom of the ball milling cutter have a large R angle corresponding to the radius of the tool to form a spherical blade shape.

  The advantages of ball milling cutter are:

  Large R angle of the blade than the end mill sharp corners stronger, not easy to collapse, that is, life than the end mill stability, in addition, for 3D processing, the ball knife processing area for the R angle blade, processing spacing and Cutting depth can be used with greater values, improved processing efficiency while also improving the quality of the machined surface.
