Manufacturers and die and mold shops can solve chatter problems in milling operations with Iscar’s ChatterFree end mills. According to the company, the cutters’ variable-pitch flute pattern eliminates harmonic vibration, the main source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling. The chatter-free feature is available in both solid carbide end mills and tips in the company’s Multi-Master replaceable-tip line. Diameter range is 0.25" to 0.75" (6 to 20 mm) for the solid carbide end mills and 0.312" to 0.75" (8 to 20 mm) for Multi-Master tips. The solid carbide version can accommodate full-slot machining up to 2 × D. Depth capability on the replaceable-tip version is more limited because the active length is shorter. In full-slotting applications on alloy steel, the solid carbide version handles 0.03 to 0.05 feed rates at 180 to 220 mm per minute surface speed and 2 × D depth of cut.
