What is the difference between a square end mill and a ball nose end mill?

  • End milling cutter and ball end milling cutter, one is ball end and the other is flat bottom. End milling cutter is mainly for conventional processing, and ball end milling cutter can be used to mill curved surface, etc.
  • The end milling cutter is generally used for milling the end face, not for milling the groove. The keyway cutter shall be used for milling the groove. Disk milling cutter is mainly used for milling large end faces, because the straight longitude of disk milling cutter is generally large, milling large end faces is faster, and saw blade milling cutter is generally used for milling.
  • When the end milling cutter rotates, the midpoint of its bottom edge is relatively static and does not have any cutting and chip removal, so it can not cut vertically.
  • The square end mills usually use side edge removal margin, the cutting depth is generally 1D (equivalent to the cutting diameter), and the cutting width can also reach 0.25D. The ball nose end mill is used for profiling, and the cutting depth and width are less than 0.1D.
