    摘要： A ring forming step includes welding opposite ends of a band saw blade including a body part having a band shape, and a tooth part including a plurality of teeth formed on one side part of the body part, to form a ring shape. A polishing step includes polishing an inner surface, an outer surface, and an end face on a side opposite to the tooth part in the ring-shaped band saw blade subjected to the ring formation. A tip tooth tip forming step includes positioning, after the polishing step, the ring-shaped band saw blade subjected to the ring formation by use of one of the inner surface and the outer surface, and the end face as references, joining a cutting tip to tooth tips of the plurality of teeth by welding, and polishing the joined cutting tip to form a tooth tip shape.

    摘要： Provided is a method of manufacturing a diamond knife for an ultra-microtome, including determining a shape and size of a knife, performing a multiphase flow analysis on movement of a droplet at a fore-end of the knife with the determined shape and size, processing a fine pattern to ensure hydrophobic property according to a result of the flow analysis, and grinding a blade of the knife after the processing of the fine pattern to minimize an interval between the pattern and the blade and, thus, a knife blade is always maintained in a wet state due to a droplet movement between a hydrophobic fine pattern and a hydrophilic surface to continuously generate ultrathin slices.

    摘要： Dynamic regulation of contact pressures in a blade sharpening system 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 dynamic cushioning and processor-controlled contact pressure between the grinding wheels and the cutting blade during sharpening. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components.

    摘要： The invention is an abrasive article for sharpening cutting blades mounted within a grinding apparatus. The article is a soft matrix in which are embedded abrasive particles, and this matrix is preferably encased within a dry and non-adherent shell or capsule. The article is capable of being fed into the apparatus, wherein it is crushed, leaving the abrasive particles free to contact and sharpen the blades by abrasion.

    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.
