A method for machining a bearing ring of a rolling bearing includes providing a blank with an annular surface for producing the bearing ring, clamping the blank in a machine tool, and structuring the annular surface by high-feed milling to form a sealing face. The method may include removing material from the blank to produce a track of the bearing ring while the blank is still clamped in the machine tool, with the blank rotating during the steps of structuring the annular surface and removing material from the blank. The method may also include providing a high-feed milling cutter with a face, and performing the high-feed milling with the face.

A manufacturing method of a casing includes a step of preparing a casing forming member that includes a casing body forming portion which is formed in a tubular shape and a protruding portion forming portion which protrudes from the casing body forming portion toward an outer side in a radial direction, a step of placing the casing forming member on a table which is rotatable about a table axis which extends in a vertical direction and disposing a tool which is rotatable about a tool axis on an inner side of the casing forming member in the radial direction, and a step of forming the casing by performing cutting an inner circumferential surface of the casing forming member with the tool while rotating the table about the table axis together with the casing forming member and rotating the tool about the tool axis.

A milling head includes a milling head base, a plurality of blades annularly arranged around the milling head base; and an actuator to rotate the milling head base. Each of the plurality of blades extends from the base at a differential radial distance as compared to a neighboring blade from the plurality of blades.
