摘要： A dressing method of a cutting blade includes a first cutting step of causing the cutting blade to cut into a dressing board held by a holding surface of a chuck table with a cutting depth that does not surpass the length of the region of roundness in the radial direction of the cutting blade to form a cut groove in the dressing board, and a second cutting step of causing the cutting blade to further cut into the groove bottom of the cut groove formed in the first cutting step with a cutting depth that does not surpass the length of the region of roundness in the radial direction of the cutting blade to carry out cutting on the groove bottom with tracing of the cut groove.

摘要： The present disclosure presents a grinding apparatus (100) which is suitable for sharpening an edge tool. The grinding apparatus (100) may comprise a grinding apparatus casing (110); a cylindrical grindstone (200) and a support element (300). The cylindrical grindstone (200) is removably attachable to the grinding apparatus casing (110). The support element (300) is also removably attachable to the grinding apparatus casing (110) for supporting the edge tool (400) to be sharpened during the grinding operation. The support element (300) includes an elongated member, which may be embodied as a cylindrical support bar (310). The cylindrical support bar (310) may be configured to extend in a direction (D) which is perpendicular to the rotation axis (R) of the cylindrical grindstone (200), during operation, in such way that a grinding operation is enabled where the edge tool (400) to be sharpened can be sharpened by means of the side surface (210″) facing outwardly from the grinding apparatus casing (110) during the grinding operation.

摘要： A device for sharpening lawnmower and sod cutting blades is provided. The blade sharpener provides a rotatable blade bed that can be used to safely adjust the grinding attack angle without exposing the operator to the moving grinding wheel. The blade bed of the present invention can be quickly adjusted over a range of different sharpening angles and is adapted for honing both right and left-sided blades.

摘要： A sharpening system for a meat grinder is provided. The sharpening system embodies two types of sharpening stones for sharpening the cutting edges of the knife blade and the hole plate, respectively, of the meat grinder, wherein each type of sharpening stone operatively associates to the drive arbor of the meat grinder. By interchangeably replacing the knife blade along the drive arbor with one type of sharpening stone so as to sharpen and resurface the hole plate, or replacing the hole plate along the drive with the other type of sharpening stone to sharpen and resurface the knife blade, the present invention provides hands-free sharpening with no additional machines or tools.

摘要： Method and apparatus for sharpening a cutting tool. In some embodiments, an abrasive endless belt is rotated in tension along a neutral plane between spaced apart first and second rollers. A guide assembly has spaced apart first and second guide surfaces which collectively converge to an intervening base surface to form a guide channel. Upon insertion of a blade of a cutting tool into the guide channel, a selected side of the blade contactingly slides against at least a selected one of the first or second guide surfaces and a first portion of a cutting edge of the blade contactingly engages the base surface to serve as a plunge depth limit stop for the blade. The endless belt is contactingly deflected by a second portion of the cutting edge away from the neutral plane to sharpen the second portion while the first portion remains in contact with the base surface.

摘要： Apparatus and method for sharpening a tool. In accordance with some embodiments, a selected side surface of the tool is placed in contacting engagement against an upper reverse sharpening guide surface that faces an abrasive surface extending along a first plane. The upper reverse sharpening guide surface is aligned along a second plane that intersects the first plane at an acute angle. A tool cutting edge contactingly engages a non-abrasive support surface disposed between the upper reverse sharpening guide surface and the abrasive surface to establish a plunge depth of the tool prior to contact with the abrasive surface. The tool is thereafter moved away from the upper reverse sharpening guide in a lateral direction across the abrasive surface while nominally maintaining the tool at the acute angle to sharpen the cutting edge in a trailing cutting edge orientation.

摘要： Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener is provided with a flexible abrasive medium having an abrasive surface and arranged along a planar extent. A guide assembly has a guide frame, a cam surface, and a pivotal guide member. A guide surface on the guide member extends at a selected angle with respect to the planar extent of the medium to support a first side of the tool during presentation of a second side and cutting edge of the tool against the abrasive surface along the planar extent. A cam follower contactingly engages the cam surface to establish the selected angle. A biasing mechanism applies a biasing force to urge the guide surface to pivot toward the planar extent to maintain the cam follower in contact with the cam surface.
