Abstract

Ved en anordning ved borhodet for en tunnelboremaskin er planet (1) gjennom kutterringenes skjærende egg lagt parallell med borhodets omdreiningsakse (2) for alle kuttere bortsett fra periferikutterne. Derved reduseres energiforbruket pr masseenhet, kutter- kostnadene reduseres og borekapasiteten økes.In a device at the drill head of a tunnel drill, the plane (1) through the cutting edge of the cutter rings is laid parallel to the axis of rotation (2) of all cutters except the peripheral cutters. This reduces energy consumption per unit of mass, cuts costs and increases drilling capacity.
