Latest Patents
Atuhiko Maeta holds a patent for a "Throwaway insert for ball end mill." This invention features an ideal cutting edge shape that corresponds to varying cutting speeds and loads at different portions of the cutting edges. The insert is designed to be high in strength and capable of discharging chips smoothly. The cutting edges form a convex curve, with the nose portion at the lowest level, ensuring optimal performance. The rake faces are designed with symmetrical, downwardly sloping convex surfaces or straight surfaces that have a positive rake angle of 5-25 degrees. The wedge angle at the cutting edges is set between 85-65 degrees, allowing for a negative rake angle at the noses and a positive rake angle at other portions. This innovative design increases the rake angle toward the side with higher cutting speeds and thickens the insert toward the side with greater load, ensuring both strength and efficiency in chip discharge.
