The present invention is a sharpening tool and sharpening system for sharpening snowmobile carbide wear rails and studs and a kit of parts that includes the sharpening tool and a steering member having a carbide wear rail. The sharpening tool is attachable to the chuck of a hand held drill and includes a shaft attachable to the chuck of the hand held drill and cylindrical head affixed to the shaft. The cylindrical head includes a rail groove surfaced in an abrasive material for sharpening wear rails.

A system for repairing dovetail slots includes a slot adaptor having a body configured and disposed to nest between first and second side walls of a dovetail slot, and a tool holder configured to be coupled with the slot adaptor. The tool holder includes a tool guidance system configured and disposed to direct a tool into contact with one of the first and second side walls of the dovetail slot. A cutting tool is mounted in the tool holder. The cutting tool includes a tapered surface configured and disposed to form a tapered recess in the one of the first and second side walls of the dovetail slot.

A single station shaper sander that uses a quick change retractable shaper and a quick change retractable profile sander is described. The shaper generates a profile in a substrate, and then the sander sands the profile in the substrate without intermediate removal of the substrate. Both the shaper and sander are retractable, moving away from the substrate when retracted, and are moved into contact with the substrate when engaged. Either an operator or automatic controls may be used to engage and retract the shaper or sander, so as to minimize operator access to dangerous moving surfaces on either. Further, each sander or shaper may have removable tools that are temporarily affixed to a spindle, affording tool changes of 15 seconds or less.

A method of machining a turbine shroud segment including inserting an annular flange of a grinding wheel through a first gap defined between the shroud retention elements and into a second gap defined between the shroud platform and an axially extending, radially inwardly facing arcuate inner surface of one of the retention elements. The wheel flange is inserted with its supporting leg and the wheel body remaining out of contact with the shroud segment and with the wheel flange remaining out of contact with the platform. The inner surface is ground through contact with an annular outer grinding surface of the wheel flange. The wheel leg and body remain out of contact with the shroud segment and the wheel flange remains out of contact with the platform during grinding.

A method of shaping a laminated glass structure includes providing the laminated glass structure comprising a flexible glass sheet having a thickness of no greater than about 0.3 mm laminated to a non-glass substrate by an adhesive layer. The flexible glass structure and adhesive layer are ground using a first tool to remove glass material. The non-glass substrate is cut with a second tool different from the first tool through a kerf formed through the flexible glass structure thereby forming a shaped laminated glass structure. A glass edge strength of a cut edge of the shaped laminated glass structure is at least about 20 MPa.

Disclosed is a milling head for shaping a shoe support for an article of foot wear. The disclosed milling head includes abrasive surfaces that are configured to allow for the shaping of an unfinished block of support material on all of the top, side and medial arch area of the perimeter surfaces without removing the block of support material from a support such as a vacuum vise, and without the need to interchange milling heads. The disclosed milling head has a semi-spherical milling surface for milling a top surface of the shoe support and two conical milling surfaces for milling a perimeter surface and a medial arch area of the perimeter surface of the shoe support, respectively. The disclosed milling head saves costs of labor and time when shaping the block of support material.

The present disclosure relates to a machining head for a gear manufacturing machine having at least one driven motor spindle and at least one counter-spindle, wherein a tool arbor having at least one tool arranged thereon is mounted between the motor spindle and the counter-spindle, and wherein at least one balancing device is integrated within the driven motor spindle and at least one balancing device is integrated within the counter-spindle.

Ultrasonic polishing systems and methods of polishing brittle components for electronic devices using ultrasonic polishing systems are disclosed. The ultrasonic polishing system may include an ultrasonic driver and a polishing head operatively coupled to the ultrasonic driver. The ultrasonic drive may have a surface shape that corresponds to a non-planar feature formed in the brittle component. The ultrasonic polishing system may also include an abrasive slurry configured to be disposed between the non-planar feature of the brittle component and the polishing head. The ultrasonic driver may be configured to displace the polishing head toward and away from the non-planar feature formed in the brittle component.

The present invention provides a method of detecting and preventing grind burn from developing on a gear. The method includes performing acoustic emission testing while the gear is being ground during a grinding operation. The grinding wheel is evaluated during an eddy current test to detect material buildup on the grinding wheel which could cause grind burn. In addition, the method includes collecting swarf from the gear during the grinding operation and inspecting the swarf for an indication of grind burn.

A polishing apparatus includes a jig unit including a substrate supporting part having a placing surface on which a substrate having a first curvature is placed. The placing surface has a second curvature corresponding to the first curvature and a polishing unit includes at least one polishing part to be rotated to polish a process surface of the substrate. The process surface of the curved substrate may be uniformly polished and foreign substances generated during the polishing process are prevented from entering into the substrate.
