Ball cutters are the absolute mainstay of 3D surface machining:
3D surface/relief processing: Carving all complex 3D shapes such as characters, animals, patterns, logos, etc. This is its primary purpose.
Surface precision machining: After rough cutting, use a ball cutter for smooth cutting to obtain a smooth surface quality.
Mold cavity processing: Processing the cavities of injection molds, die-casting molds, and other molds, which are mostly curved surfaces.
Concave processing: Processing grooves with circular arcs inside.
Slope milling/contouring: Cutting along the contour of a curved surface.
