FIELD: medical engineering.
SUBSTANCE: method involves machining a billet giving it shape and sharpening the cutting part. Ruby monocrystal boules are used as raw material of the billet, grown up in crystallographic direction of [1011]. They are split into half-boules in [1120] direction, and then cutting into plates. Cutting is carried out in direction set in perpendicular to half-boule crystallographic axes. Before sharpening tool cutting part shaped as cutter, hydrothermal ruby monocrystal plates etching is carried out, to determine tool cutter cut-off directions in crystallographic directions of [1210], [1011] and [0111].
EFFECT: high precision cutting tool possessing increased strength and usable in eye microsurgery.
