摘要： Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener includes an abrasive medium having an abrasive surface. A stationary tool support guide provides a guide surface that supports a side of the tool during presentation of a cutting edge of the tool against the abrasive surface. A rotatable edge guide has a roller member with a curvilinearly extending outer surface. The roller member is rotatable about an edge guide roller axis to engage, via rolling contact, the cutting edge during the presentation of the cutting edge against the abrasive surface.

摘要： A multi-procedure integrated automatic production line for hard alloy blades under robot control is provided. The production line includes a rail-guided robot. A cutter passivation device and a blade cleaning and drying device are arranged on one side of the rail-guided robot. A blade-coating transfer table, a blade coating device, a blade boxing transfer table, a blade-tooling dismounting device and a blade boxing device are sequentially arranged on another side of the rail-guided robot. The blade-tooling dismounting device is arranged on one side of the blade boxing transfer table. The production line further includes squirrel-cage toolings for carrying the blades. The squirrel-cage tooling that are loaded with the blades can run among the cutter passivation device, the blade cleaning and drying device, the blade-coating transfer table and the blade boxing transfer table. The blades after being treated through the blade-tooling dismounting device are sent to the blade boxing device.

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.

摘要： A honing apparatus includes a sharpening stone that has a sharpening surface configured to sharpen the edge of the blade upon engaging contact with the edge of the blade. A frame is operatively coupled to the sharpening stone, and a weight element is supported by the frame and positioned so as to urge the sharpening stone toward the edge of the blade. The frame may be pivotally coupled to a fixed element at a pivoting location, and the weight element may be positioned so as to create a moment about the pivoting location, with the moment urging the sharpening stone toward the edge of the blade.

摘要： The present invention provides a sound level meter that may be removably coupled to a saw blade sharpening apparatus to aid in safe, reliable, reproducible and effective saw blade sharpening. The sound level meter is adapted to be removably attached to the saw blade sharpening apparatus and to provide accurate and reliable indication of interference between the saw blade and the saw blade sharpening stones. The sound level meter is capable of detecting interference even in the often noisy operating environment.
