How to select end mills for cutting aluminum

Three flutes end mills for aluminum and one flute spiral bits for aluminum are often used during the cutting process of aluminum sheets. For processes that require a milled base, three flutes end mills for aluminum are generally used. The applicable spindle rotation speed is around 8000 per minute, and the feed speed is adjusted according to different situations. Three flutes end mills for aluminum are characterized by their sharpness and large chip slots. Combined with the colorful Diamond-Like Carbon (DLC) coating, they can reduce the coefficient of friction and improve heat dissipation efficiency, making them highly suitable for the milling of aluminum materials.

The cutting of aluminum sheets is usually carried out on engraving machines, where one flute spiral bits for aluminum are commonly used. Depending on the characteristics of different aluminum materials, different one flute spiral bits for aluminum are selected. For aluminum materials of 4 series and below, it is suitable to use our "DOURUY" brand 2A-grade one flute spiral bits for aluminum dry cutting. These cutters are applicable for spindle rotation speed of 20,000 per minute. Our 2A-grade one flute spiral bits for aluminum are known for their high sharpness, low cutting noise, and effective chip removal. With the addition of a specialized colorful DLC coating, the processing efficiency and tool life are significantly increased. For aluminum materials above 4 series, due to their higher hardness, it is more appropriate to use our "DOURUY" brand 3A-grade one flute spiral bits for aluminum. The 3A-grade aluminum end mills employ a unique edge protection process, which makes cutting harder aluminum materials less likely to chip and increases the durability of the end mill. With the specialized colorful DLC coating, the end mill exhibits great longevity.
