Claims (1)

Способ эксплуатации прямоугольных двухслойных пластин, включающий многократную отработку установленного выпуска режущих кромок, многократную переточку изношенных граней и последующее многократное использование переточенных граней для резания пород забоя, отличающийся тем, что после каждого акта износа выпуска режущей и калибрующей кромок двухслойной режущей пластины к противоположным им опорным граням прикрепляют пайкой или приклеиванием стальную пластинку толщиной, равной величине износа выпуска соответствующей рабочей грани, и шириной, равной толщине пластины, затем отработавшиеся по высоте до угловой зоны режущие пластины снимают с коронки и устанавливают по внешнему и внутреннему диаметрам корпуса твердосплавной коронки, при этом ее грань, выполнявшую ранее функции резания, используют в качестве калибрующей стенки скважины.A method of operating rectangular double-layer inserts, including repeated testing of the established release of cutting edges, repeated regrinding of worn faces and subsequent repeated use of the grinded faces to cut the face rocks, characterized in that after each act of wear of the output of the cutting and calibrating edges of the double-layer cutting plate to the opposite support faces attach by brazing or gluing a steel plate with a thickness equal to the amount of wear of the release of the corresponding working face, and a width equal to the thickness of the insert, then the cutting inserts worked out in height to the corner zone are removed from the crown and set according to the outer and inner diameters of the carbide crown body, and its face, which previously performed the cutting function, is used as a calibrating well wall.
