FIELD: process engineering.
SUBSTANCE: end milling cutter with outer diametre D represents an end spherical milling cutter and comprises body to be secured in machine and cutting part with multiple chip groves. Rear part of every tooth comprises short peripheral unloading section starting on cutting edge and arc-like rear surface running along tooth length and adjoining said peripheral unloading section to terminate in angle-piece arranged at distance C from outer diametre D. Said peripheral unloading section smoothly fairs with arc-like rear surface via concave small-radius lip. Said distance C makes 0.06 D or less, while said angle-piece serves to polish machined surface.
EFFECT: higher surface quality.
