Title: SEPARATING BLADE FOR PROCESSING A HARD MATERIAL, AND TOOL
Abstract:
The invention relates to a separating blade (1) having a machining section (2) for the material-removing machining of a mineral-containing hard material, wherein the separating blade (1) is designed to be set into rotation by means of a drivable flange arrangement (24), and wherein a liquid coolant can be supplied to the separating blade (1) for a machining operation. According to the invention, in an inner volume (8) of the separating blade (1) that is encompassed by parts of the separating blade (1), an inner structure for providing a flow path between an inlet point (29) and an outlet point (30), through which the coolant can flow, is designed in such a way that in the connected state with the flange arrangement (24), an outflow of portions of the supplied coolant from the internal volume (8) is prevented along the flow path during the machining operation of the separating blade (1) such that no coolant reaches the machining section (2) on the outside of the separating blade (1).
