On the problem of machining center milling cutter

End milling cutter: it is the general name of cylindrical milling cutter, which can be divided into 2-edge (i.e. keyway milling cutter), 3-edge and 4-edge according to the number of edges. That's all I used. )

Keyway milling cutter: Keyway milling cutter is also a kind of end milling cutter. The difference is that the keyway milling cutter can directly "step on the knife" to cut the solid material in Z direction, but the end milling cutter can't. The end milling cutter must use oblique cutting or spiral cutting, or make "hole cutting" first. As the name implies, keyway milling cutter is generally used to open keyway on shaft.

Square shoulder milling: Square shoulder milling is the name of processing method. Usually we are talking about face milling and side milling. Square shoulder milling is actually side milling, and some are also called copying milling.

Corn milling: The corn milling cutter is an efficient processing tool now. Generally speaking, the whole blade of traditional end milling cutter has become a replaceable tool with blade. Its processing form belongs to a way of side milling. Its advantage is high processing efficiency. However, the rigidity of general BT40 machine tools may not be reached.

The materials of milling cutter are: Bai Gang, tungsten steel and cemented carbide blades. In addition, there are many coated tools, that is, coating a special material on the existing tungsten steel tools can improve the cutting effect and prolong the tool life.

What's the use of the blade passing through the center? You should have these introductions in your materials here. The blade of keyway milling cutter is eccentric and can "cut" directly on solid materials. Other milling cutters do not have this characteristic, so they need to use diagonal, spiral or "hole-dropping" mode to "cut".

Finally, I have some information for your reference if you need it. Just leave me an email address.
