O que é um Tapered Ball Nose End Mill?
A Tapered Ball Nose End Mill is a cutting tool made in a conical shape with a rounded end. This type of tool serves very well in the Z” cutter, which is used to cut small features, particularly for 3D contouring and complex surface machining. The taper on the tool makes it sturdy; thus, there is better control over the tool with reduced deflection while cutting. This is important when cutting harder materials or where fine detail is required. Such end mills are widely applied in the woodworking, molding, and aerospace industries, where detailed, well-fitting, and polished joints are highly needed.
Compreendendo o Tool Design
In tapered ball nose end mills, the geometry of a parabola with a rounded end is combined with a tapering profile. The tapering angle helps to reduce deflection, which gives more rigidity and accuracy while cutting detailed 3D shapes. This situation is more beneficial when the materials require delicate and smooth surfaces. Also, the round nose provides a smoother cut, which reduces the chances of having tool marks, improving the workpiece’s quality. Common materials used in making these tools are strong carbide, which maintains a sharp edge for a long time during use, such as in mechanical and aerospace industries and other industries.
