Ball endmills typically feature an arc radius (R) equivalent to half the diameter, with smaller sizes resulting in smaller R values, necessitating the use of small pitch (PF) to achieve an impeccable surface.
NS Tool developed a special model, where the arc resembles the characteristics of a lens featuring a longer radius. During milling operations, if equal Cusp height values are required, PF can be increased further to reduce milling time while still maintaining the smoothness of the surface, especially for the workpieces with relatively flat surfaces, making this type of endmill exceptionally well-suited for such applications. The notable difference can be seen from the pictures.
Designed to facilitate milling operations and enhance productivity in comparison to general endmills, a specialized MUGEN COATING PREMIUM is created for wear resistance, ideally suited for machining high-hardness steels ranging from pre-hardened steels to hardened steels up to 65 HRC. However, its limitation is that it is not suitable for applications involving side walls and work surfaces with inclinations exceeding 21° from the ground.
