END MILL HAVING FLAT BACKOFF, HAVING REINFORCED RIGIDITY Russian patent published in 2020 - IPC B23C5/10

Abstract RU 2714268 C1

FIELD: technological processes.

SUBSTANCE: invention relates to machining of materials and can be used in designs of end mills used for processing heat-resistant alloys. Cutter has eccentric flat backoff, which comprises at least three flat surfaces continuously located along trajectory of eccentric occiput. End mill of proposed design combines advantages of flat occipital and eccentric occiput.

EFFECT: higher rigidity, improved heat release during processing.
