Solid carbide roughing end mills for Aluminum,3 flute carbide end mill,carbide end mill cutter

Most end mills for aluminum have 3 flutes, to get a comparable strong flute, and at the same time enough large chip groove for the fast chip removal, avoid the sticking chip to form the built-up edge under the rising cutting temperature. There are also 2 flute and single flute end mill for aluminum machining.

Common popular size of roughing carbide end mills.

End mill for milling aluminum alloy has the following main characteristics: 1, Low hardness material milling in the low temperature and high speed. The HRC hardness of common aluminum alloy is below HRC 40 degree, which is a low hardness compared with titanium alloy and other quenching steel, therefore, when milling aluminum alloy, the end mill load is small. And because of the good thermal conductivity of aluminum alloy, the temperature of milling is low, so the milling speed can be very high. 2. Should solve the chip sticking problem. The plasticity and melting point of aluminum alloy are low. When milling the aluminum alloy, the chip sticking end mill problem is serious, which cause a poor removal performance and the coarse milling surface. End mill for aluminum should solve those two problems by end mill carbide grades selection, coating and flute design. Aluminum end mills often made to be 3 flutes, in few situations, 2 flute ball nose end mill or 4 flute flat end mill may be applied. No coating, DLC coating or AD coating. 3. Select proper carbide grade for aluminum end mills. For the chip sticking problem, Betalent use carbide grade BT50 as carbide material, 10% cobalt content, not too hard or too soft. 4,Increase relief angle to get a larger chip groove,reduce the chip sticking.
