摘要： The invention relates to a method and a rock drilling rig for drilling a hole in a rock. In the method the hole is drilled with a so-called top-hammer rock drilling rig including a drill rod and a cone roller bit at the end of the drill rod. During drilling with the percussion device, stress pulses of low amplitude are produced at a high frequency of at least 200 Hz. In the rock drilling rig, the cone roller bit (3) at the end of the drill rod and the percussion device are configured to feed stress pulses of low amplitude, at the frequency of at least 200 Hz, via the drill rod and the cone roller bit to the rock.

摘要： The invention relates to a percussion device having a frame, a tool mounted movable in its longitudinal direction, the percussion device containing a work chamber having a movably mounted transmission piston to compress the tool so that a longitudinal stress pulse is generated to the tool, inlet and outlet channels for conducting the pressure fluid to the percussion device and away from it and a control valve that alternately directs the pressure fluid from the inlet channel to the work chamber to act on the transmission piston and, correspondingly, discharges the pressure fluid from the percussion device. The percussion device and trans-mission piston have channels that connect the pressure fluid that acted on the transmission piston to flow during the return movement of the transmission piston through the control valve and transmission piston to the pressure fluid outlet channel and cut off the flow when the transmission piston has returned to its initial position.

摘要： A button and a rock drill bit for percussive drilling including a bit head attached at an end of a drill element of a drilling assembly. The bit head has at a front end, as seen in the intended drilling direction, a plurality of buttons distributed over the bit head to engage material to be crushed. At least one of the buttons has a shank portion made of a substrate material of particles of a first material embedded in a binder phase. The first material is harder than the binder phase. The shank portion at least partially forms a bearing portion, the material of which is harder than the binder phase. At least one of the buttons is allowed to rotate about its own respective symmetry axis.
