Solid carbide end mill for Aluminum, 3 flute end mill cutter, Long
end mill, solid carbide end mill bit
There are many types of milling machines, such as ordinary milling
machines and CNC milling machines for processing grooves and linear
contours, milling and boring machining centers for processing
cavities, cores, and surface contours/contours.Different milling
machines require different milling cutter to finish the particular
machining function.
The milling cutter is roughly divided into:
1,Flat end milling cutter: for fine milling or rough milling,
milling grooves, removing a lot of blanks, small area horizontal
plane or contour finishing;
2,Ball end milling cutter: semi-precision milling and precision
milling of curved surfaces; small cutters can finish milling small
chamfers on steep surfaces/straight walls.
3,Corner radius milling cutter: for rough milling with small
surface changes, fewer narrow and concave areas, and more
relatively flat areas.
4,Chamfering milling cutter: With chamfering, it can be used for
rough milling to remove a large amount of blanks, and it can also
be used for fine milling of small chamfers on the flat surface
(relative to the steep surface). Chamfering milling cutters are
divided into milling cutters for round chamfering and oblique
chamfering.
5,Forming end mills: including chamfer cutters, T-shaped cutters or
drum cutters, tooth cutters, and inner R cutters.
6,T-shaped milling cutter: can mill T-slots.
7,Tooth type milling cutter: mill various tooth types, such as
gears.
8,Roughing end mill: Roughing end mill is designed for fast rough
milling aluminum alloy, copper alloy or soft steels.
For milling workpiece of which hardness is below HRC 50 to 55
degree, carbide grade BT50 is applied as raw material(ground
carbide rod), BT45 has below physical characters:
| Grade | Co% | Grain Size | Density (g/cm) | Hardness(HRA) | TRS N/mm2 | Application |
| BT50 | 10 | 0.6 | 14.45 | 92.3 | 4400 | Common milling |
| BT55 | 12 | 0.4 | 14.1 | 92.6 | 4600 | Fine milling |

End mill Chip flute/cutting edge: The groove of the milling head is a deep spiral groove running
along the cutter, and the sharp blade along the edge of the groove
is called an edge. The blade cuts the material, and the chips of
the material are pushed out of the chip flute through the rotating
drill. Each flute almost always has one blade edge, but some
cutters have two edges per flute. Generally, chip flutes and
cutting edges can be used interchangeably. Milling cutters may have
one or more edges, the most common are 2-edge, 3-edge and 4-edge.
