The helix angle of the aluminum endmill is divided into a 45 degree helix angle and a 55 degree helix angle. The 45 degree helix angle is usually called a double ligament. The 55 degree helix angle is usually called a ligament. Double ligament aluminum end mill more commonly used, more rigid, single ligament aluminum end mill is more sharp, less rigid and double-edged with aluminum end mill nose end mill with R0.5 and R1, generally no special indication on the default is R0.5, R0.5 round nose mill is also more commonly used flat end mill has two edges and four blades, four blade more commonly used, generally no special instructions, the default for the four blade flat end mill aluminum end mill is also divided into three blades and two Blade, no special instructions, but also the default is the three-edged. Two-edged aluminum blade is smoother
