Abstract
Milling tool formed for hobbing of workpieces having cogs has a cylindrical tool body defining a rotation axis and a plurality of disc-shaped segments. Each segment includes a hub part having two opposite plane-parallel end surfaces extending perpendicular to the rotation axis, and a peripheral cam having a plurality of tangentially spaced-apart milling inserts. Bordering segments are detachably interconnected by male and female members co-operating in pairs and situated with the rotation axis extending through the members, each of which include a contact surface converging from a big end toward a small end and, in a cross-section across the rotation axis, form an out-of-round curve. Contact surfaces are dimensioned so that, when members are brought together, they direct their two bordering segments toward an end position centered and mutually angularly determined by the out-of-round cross-section curve and where plane-parallel end surfaces abut against each other. An individual segment is disclosed.
