What does the end mill have on the end teeth through the center?
One tooth is over center, that is, there is end edge over center position. What time should I note, for example, when the keyway milling keyway milling, without tooth groove milling center, will be out of the middle is high, so the 2 blade keyway milling cutter is a pair of teeth are center.If the cutter is used to work week tooth, then end teeth but no center, in general, when we produce tool, odd blade cutter, a cutter tooth center, even, have a pair of teeth over center.2 edged cutters, sometimes one to center, and sometimes one tooth across center.
The end mills can be divided into high speed steel end mills, welded alloy end mills and integral alloy end mills according to different materials. According to the use function, the end mill can be divided into: end milling cutter with horizontal edge (that is, as you said, over center end mill) and different transverse edge end mills. With horizontal vertical milling cutter can be used for side milling, slotting cutter, perpendicular to the direction of processing (but not too deep), the center, 2 vertical milling cutter blade cross connected together, 3 vertical milling cutter blade 1 core, 4 vertical milling cutter 2 transverse blades are connected together, the other two disconnected. Without a horizontal edge end mill, it can not be machined perpendicular to the tool direction without having a central blade.I don't know. Can you understand that?...
There is one tooth across the center. That is, when machining vertically, you can drill like a drill bit (usually a vertical milling cutter is impossible because the blade is not center)
