FIELD: various technological processes; medicine.
SUBSTANCE: invention relates to methods of making structural elements of cutting devices. Method of making a blade for a microtome consists in the fact that, first, a sapphire plate is preliminarily sharpened with the help of a diamond tool, thereby forming a cutting edge. Total depth of sapphire layer removal during cutting edge processing on each side is not less than 2/3 of blade thickness. Further, the cutting edge of the blade is mechanically polished. Blade is cut on non-working sides. Then the blade is annealed in a vacuum furnace at a temperature of not less than 1,200 °C. During annealing, a pressure of not more than 1×10-5 mm Hg. After annealing, the obtained article is left to cool down in a vacuum to ambient temperature.
EFFECT: higher quality of histological sections.
