Design principles and core advantages of double-edged ball end milling cutters

The double-edged ball end milling cutter adopts a 180 ° symmetrical double helix blade solid hard alloy structure, which is formed by five axis precision grinding technology. The ball end cutting edge has a continuous and smooth arc. The core design principle is a double-edged symmetrical layout to achieve cutting force balance, coupled with a large opening chip groove structure, balancing the rigidity of the tool body with efficient chip removal performance, and further optimizing cutting conditions with wear-resistant coatings, suitable for high-speed precision machining scenarios.
The core advantage of this tool is outstanding. Compared with multi blade ball cutters, the chip holding space is greatly increased, which can effectively avoid chip blockage and heat accumulation problems, and is suitable for soft metal and deep cavity machining. The symmetrical structure can counteract radial cutting forces, significantly reduce machining vibration and deflection, and have no obvious tool marks in curved cutting, resulting in excellent machining smoothness. At the same time, the cutting load of the tool is small, the wear is uniform, the service life is longer, and it can be integrated to complete semi precision and precision machining of complex 3D surfaces and cavities. The process adaptability is strong, and it is widely used in precision machining fields such as molds, aviation, and automobiles.
