    摘要: A grinding wheel includes a disc-like member and a grinding stone layer disposed on an outer peripheral surface of the disc-like member. A grinding surface of the grinding stone layer includes a cylinder grinding surface, end grinding surfaces, and corner grinding surfaces. The grinding stone layer includes a cylindrical-portion grinding stone layer including a part of the corner grinding surfaces and the cylinder grinding surface, and end grinding stone layers including the remaining part of the respective corner grinding surfaces and the respective end grinding surfaces and having a property different from a property of the cylindrical-portion grinding stone layer. Joint surfaces are each formed by joining a boundary surface of the cylindrical-portion grinding stone layer and a boundary surface of the end grinding stone layer such that the boundary surfaces have a preset inclination α to an axis of rotation.

    摘要: The invention relates to an abrasive medium which is bonded with a thermosetting material and comprises abrasive particles, a thermosetting binder and optionally further fillers, and contains a phosphate-based additive, the percentage of the phosphate-based additive being 1 to 10 wt.-% of the starting mixture of the abrasive medium. The phosphate-based additive is homogeneously distributed in the abrasive medium. The invention also relates to a method for producing corresponding thermosetting resin-bonded grinding disks.

    摘要: A blade sharpening system for log saw machines is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply a dynamically cushioned pressure between the grinding wheels and the cutting blade. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components. The padded grinding wheels decrease fire risk, and the tensioner can be operated remotely, decreasing human injuries common with conventional setup actions near the sharp cutting blade.
