An apparatus, system, and a method for sharpening a cutting tool. The system sharpens cutting tools by manipulating the tool, measuring the three dimensional profile of the tool, and then grinding the tool. The apparatus consists of a robot capable of six degrees of motion, a gripping mechanism, a force-torque sensor capable of at least two directions of force and/or torque, a three dimensional scanning subsystem, a loading subsystem, a user interface, an initial orientation scan subsystem, a data processing and robot control subsystem, and at least one grinding system comprising two counter-rotating grinding wheels. The method automates the grinding process so that dull cutting tools can be placed into the loading system, sharpened by the system, and then ejected fully honed.

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.

A system and method for sharpening a tool, such as a cuticle nipper, is provided. A first abrasive component has first abrasive surface and a second abrasive component has a second abrasive surface. A motor drives the first and second abrasive components. A securing device secures the tool. A positioning device receives the securing device and permits movement of the securing device relative to the first and second abrasive devices.

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.

A wheel fixture is disclosed. A main shaft drives a first positioning pull rod on a chuck body to extend and contract in the radial direction via a tightening screw, a clamping jaw is at a position within the travel range of extension and contraction, a wheel is positioned and clamped by the fixture, airtight support blocks are pressed down by the wheel and flush with the support plane of the clamping jaw, at this time, airtight ejector rods press second O rings to prevent air from flowing out of the airtight detection position, a detection system of a machine tool detects a preset air pressure value which indicate that the wheel has been placed correctly, and if the wheel is not placed correctly on the fixture, the machine tool will alarm through the detected pressure feedback.

A portable sharpener for chains of chainsaws comprising sharpening means (2) and a coupling device (3).

The sharpening means (2) are configured to sharpen the teeth (102) of a chain (101) of a chainsaw.

The coupling device (3) supports the sharpening means (2) and is configured to be reversibly constrained to the chainsaw.

Furthermore, the coupling device (3) comprises a support structure (4) which has a first plate (4a) adapted to be arranged parallel to a main extension plane of a chain guide bar (100) of the chainsaw and a second plate (4b) configured to abut against the bar (100), in such a way as to be at least partly interposed between the bar and the chain (101).

The first and the second plate (4b) are arranged substantially in an L-configuration.

The coupling structure further comprises one or more attachment members (5) applied to the first plate (4a) and configured to constrain the support structure (4) to the bar (100) of the chainsaw.

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.

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.

A knife sharpener for the manual sharpening of knives that includes a knife clamp member having first and second clamping members, a guide member that defines upper and lower guide members, and a base member. Each upper and lower guide member includes a plurality of apertures sized and shaped for receiving a guide rod that includes a sharpening stone. The knife clamp member further includes embodiments assuring the knife blade is held securely and positioned between the first and second clamping members in the same position in which the knife blade was installed the last time it was sharpened.

A throwaway insert includes a base and a cutting edge member. The cutting edge member includes: a rake face; a flank face extending to cross the rake face; a first connecting face connecting the flank face to a side surface of the base and extending to cross the rake face; and a first ridgeline formed by the rake face and the flank face and serving as a cutting edge. When viewed in a plan view from the upper surface of the base, the flank face and the first connecting face are located external to the base. A second ridgeline formed by the rake face and the first connecting face crosses the first ridgeline at an obtuse angle.
