摘要： A cutting bit for a bit assembly secured to a cutter head includes a cutting end, a shank extending along a bit axis, and a shoulder positioned between the cutting end and the shank. The shoulder includes an outer edge defining a perimeter, a shoulder end surface defining a shoulder plane, a first inclined surface and a second inclined surface. The first inclined surface is positioned between the outer edge and the shoulder end surface. The first inclined surface extends along the perimeter and is oriented at a first acute angle relative to the shoulder plane. The second inclined surface is positioned between the shoulder end surface and the first inclined surface. The second inclined surface is oriented at a second acute angle relative to the shoulder plane, and the second acute angle is smaller than the first acute angle.

摘要： A rotatable cutting tool (10) includes a cutting tool body (12) having an axial forward end (14) and an axial rearward end (16). A bolster (46) at least partially received in a head portion (22) and includes a convex-shaped head portion (56) with a socket (20), a collar portion (58) and a tapered shank portion (60). The socket (20) is formed with a substantially planar side wall (20a), a bottom wall (20b), and a radius blend (20c). A hard tip or cutting insert (18) is at least partially received in the socket (20) of the bolster (46) and includes a convex-shaped conical head portion (72), a collar portion (74) and an axially-rearward portion (76) that generally conforms to the geometry of the socket (20) of the bolster (46). Between about sixty percent (60%) and about ninety percent (90%) of the cutting insert (18) is received in the socket (20) of the bolster (46), thereby reducing forces and stresses transmitted to the cutting tool (10) during a machining operation.

摘要： The invention relates to a tool device for a ground milling machine, particularly a road milling machine, a recycler, a stabilizer or a surface miner. The tool device comprises a milling chisel with a highly wear-resistant chisel tip, particularly comprising PCD material, and a chisel shaft extending along a longitudinal axis, and a chisel holder with a shaft receptacle, the chisel shaft of the milling chisel having at least one tapering section narrowing in a direction away from the chisel tip. Furthermore, a fastening device is provided, which is designed in such a way that it pulls the milling chisel along its longitudinal axis and in the direction away from the chisel tip into the shaft receptacle, the shaft receptacle of the chisel holder being designed complementary to the chisel shaft of the milling chisel in such a way that the tapering section, when braced by the fastening device, bears against the chisel holder in the shaft receptacle in a frictionally locking manner shaft receptacle. The chisel holder also comprises a base holder and a quick-change chisel holder, the base holder comprising a holder receptacle for receiving the quick-change chisel holder, and the quick-change chisel holder comprising the shaft receptacle, and the fastening device being designed in such a way that it pulls both the milling chisel along its longitudinal axis and in the direction away from the chisel tip into the shaft receptacle as well as the quick-change chisel holder into the holder receptacle in the base holder. The invention also relates to a milling chisel and a quick-change chisel holder for such a tool device and a ground milling machine with such a tool device.

摘要： A tool holder is disclosed for use with a milling drum. The tool holder may have a cylindrical body defining a first end and a second end, the first end configured to be received within a tool mounting block of the milling drum, the second end configured to receive a cutting bit. A flange may be located between the first and second end with respect to an axial direction, and a first bore, with a first opening defined by the second end and extending towards the first end. A frustoconical portion may be located between the flange and the first end with respect to the axial direction and a cylindrical portion located between the flange and the first end. At least one radial opening may pass through at least the wall of the cylindrical portion to intersect or be open to the first bore.

摘要： A milling drum adapted to be rotated in a cutting direction about an axis defined by the cylindrical surface of the drum. A plurality of pairs of overlapping recesses in the cylindrical surface of the drum. A tooth or cutting bit with a base configuration matching a first of the pair of the overlapping recesses, and a lower portion of a side surface including a retainer engagement feature. A retainer has a base configuration matching a second of the pair of overlapping recesses, and a side surface including a tooth engagement feature. A fastener secures the retainer in the second of the overlapping recesses so that the tooth engagement feature of the retainer engages the retainer engagement feature of the tooth or cutting bit to hold the tooth or cutting bit in the first of the overlapping recesses.

摘要： A bit assembly for a cutting drum includes a sleeve and a bit. The sleeve includes shank portion, a flange positioned, and a bore extending through the flange and the shank portion. The flange includes a first end surface, a second end surface, and a sleeve outer surface extending between the first end surface and the second end surface. A portion of the sleeve outer surface positioned adjacent the first end surface defines a sleeve profile. The bit includes a cutting end, a shank, and a shoulder positioned between the cutting end and the shank. The shank is positioned within the bore, and the shoulder is positioned adjacent the first end surface of the sleeve. A bit outer surface extending between the cutting end and the shoulder. A portion of the bit outer surface positioned adjacent the shoulder defines a bit profile that corresponds to the sleeve profile.

摘要： An improved tooth for a roller crusher is presented. The tooth can include a first tungsten carbide overlay layer plasma-transfer arc welded on a recessed hemispherical end of the tooth, which is covered by a wearable cap placed over the first overlay layer, the cap welded to the tooth. A second tungsten carbide overlay layer can then be plasma-transfer arc welded over the cap to, thereby, provide a tooth having two tungsten carbide overlay wear layers.

摘要： A cutting bit assembly includes a block, a bit sleeve, and a seal. The block includes a first bore and a fluid passage. The fluid passage includes a first portion and a second portion in fluid communication with the first portion. The first portion is oriented obliquely with respect to the first bore, and the second portion extends at least partially around the perimeter of the first bore. The bit sleeve includes a shank, a flange, and a second bore extending through the shank and the flange. The shank is positioned within the first bore of the block such that a surface of the flange engages a first end surface of the block. The seal is positioned between the second portion of the fluid passage and the shank to prevent contact between a fluid in the fluid passage and the outer surface of the shank.
