Abstract

Nóż do skrawania skał z hydrodynamicznymi obrotami wokół osi charakteryzuje się tym, że na powierzchni części chwytowej (1) trzonka noża posiada co najmniej dwa rowki śrubowe (2) o kącie nachylenia β = 25 ÷ 75° względem osi podłużnej noża oraz obwodowe wybranie (3) w strefie przejściowej części chwytowej (1) trzonka noża w jego część roboczą w postaci oprawy ostrza (4).A knife for cutting rocks with hydrodynamic rotation around the axis is characterized by the fact that on the surface of the gripping part (1) of the knife shaft it has at least two helical grooves (2) with an angle of inclination β = 25 ÷ 75° relative to the longitudinal axis of the knife and a circumferential recess (3 ) in the transition zone of the gripping part (1) of the knife shaft into its working part in the form of the blade holder (4).
