摘要： The present invention relates to a rock drill bit (1) for percussive drilling, especially top hammer drilling. The rock drill bit (1) comprises a bit head (3) provided with rock crushing means (11), and a skirt (5). The drill bit (1) is provided with a number of grooves (16) for drill cuttings on the outside of the skirt (5) which extend in the axial direction of the drill bit (1). Protruding lands (17) are defined between the grooves (16) for drill cuttings, which likewise extend in the axial direction of the drill bit (1). The drill bit (1) has means (9) for connecting the drill bit (1) to a drill rod (7). At least some of the ends of the lands (17) facing away from the rock-crushing end of the drill bit (1) are formed which retrac teeth (18). The distinguishing feature of the drill bit according to the present invention is that each retrac tooth (18) has an edge (19), which extend along the circumference of the skirt (5). The present invention also relates to a method for manufacturing of a rock drill bit according to the present invention.

摘要： The present invention describes a coated CBN cutting tool for metal machining. The tool consists of one or more CBN bodies with or without cemented carbide backing. The coating is composed of one or more layers of refractory compounds of which at least one layer consists of fine-grained, crystalline η-phase alumina, Al2O3, with a grain size less than 0.1 νm. The η-phase alumina is deposited with a Plasma Activated Chemical Vapor Deposition (PACVD) process in which the plasma is produced by applying a bipolar pulsed DC voltage across two electrodes to which the tool substrates to be coated are fixtured and electrically connected.

摘要： The present invention relates to a process for producing a coated cutting tool consisting of a coating and a substrate, wherein at least one refractory layer consisting of fine-grained, crystalline η-Al2O3 is deposited by reactive magnetron sputtering onto the moving substrate in a vacuum by pulsed magnetron sputtering in a mixture of a rare gas and a reactive gas at a pulse frequency set for 10 to 100 kHz. The deposition occurs with a rate of at least 1 nm/s with reference to a stationarily arranged substrate at a magnetron target power density in time average set for at least 10W/cm2. The substrate temperature is in the range of 400 to 700 °C and the flux of impinging particles onto each individual substrate is cyclically interrupted.

摘要： The present invention relates to a rock drilling tool, a ring drill bit and an adapter for percussive drilling. The rock drilling tool (10) is intended to be connected to a casing tube (46) and a drill rod (62) in order to form a borehole. The casing tube is intended to be used as a channel for drill dust. The rock drilling tool comprises: - a drill adapter (20), including a flush duct for a flush medium, first drivers in order to transfer rotation, - a central pilot drill bit (12) provided with rock cutting members (14) and detachably connected to the first fastening means (21, 22) of the drill adapter, - a ring drill bit (17), provided with rock cutting members (41), and arranged to surround parts of the drill adapter during drilling, whereby the ring drill bit comprises second drivers intended to co-operate with the first driver of the drill adapter in order to rotate the ring drill bit with the drill adapter, and a casing shoe (18), intended to be secured to the casing tube as well as the ring drill bit, at least in connection with drilling, which casing shoe is arranged to push the casing tube only in the axial direction of the tool, whereby the casing tube (46) and the ring drill bit may be left in the borehole after finished drilling.
