Abstract:
The present invention relates to a bench grinder apparatus. The object of the invention is to provide a bench grinder apparatus and a method for safe and exact grinding of tools, and at the same time minimizing the damage to the tools and to the user during grinding. Bench grinder apparatus for grinding tools comprising: - at least one grinding wheel with a grinding surface arranged in a wheel casing, where the wheel casing is provided with one working opening which provides an access to a part of the grinding surface, - an operational means arranged in relation to said grinding wheel, capable of rotating the grinding wheel, - at least one tool rest moveably attached to the wheel casing, and arranged in a prede- fined distance to the grinding wheel, - at least one angle adjustable means capable of moving the tool rest in said predefined distance to the grinding wheel from a first grinding angle position to a second grinding angle position.
Abstract:
A skate blade sharpening system used to sharpen the blades of ice skates. The skate sharpener can include a housing that includes an elongated slot for receiving the blade of an ice skate for sharpening, and clamp jaws for retaining the skate. The housing can include at least one slot cover to engage the skate blade. Engagement of the skate blade can be sensed by a controller to enable sharpening operations to proceed. The skate blade sharpening system can automatically operate a grinding wheel and move the rotating grinding wheel back and forth along the lower face of the skate blade a desired number of times to sharpen the skate blade.
Abstract:
A device for removing an information-bearing layer of an optical disc comprises a housing defining a first chamber and a second chamber, a mount to selectively mount an optical disc having an information-bearing layer adjacent the first chamber, a cutter within the first chamber, a drive mechanism operatively connected to the cutter, and a passageway between the first and second chambers. The cutter causes the information-bearing layer of the disc to form particulate matter, and the particulate matter is caused to move through the passageway into the second chamber. The resulting particulate matter has a particle size less than about 326 microns to meet the standards of the Department of Defense and NIST for digital data destruction.

Abstract:
A universal sharpening apparatus for sharpening a tool includes a grinding wheel assembly (14) and a universal clamping system (18) for clamping the tool rigidly in any of a wide range of spatial relations to the grinding wheel. The universal clamping system includes two arcuate bearings (20, 22) each having an effective axis of rotation. The arcuate bearings are mechanically interconnected so as to be deployable with their respective axes of rotation parallel such that opposing rotation of the arcuate bearings generates a non-rotational displacement of the tool relative to the grinding wheel.
Abstract:
The present disclosure provides for a skate sharpening system comprising an operative unit and a base, the operative unit comprising a central body, the central body comprising a skate receiving slot, a skate clamp being positioned adjacent to the skate receiving slot such that a skate can be secured within the skate receiving slot for a sharpening operation, the operative unit further comprising a grinding unit, the grinding unit being configured to translate along a length of the slot such that the grinding unit can conduct the sharpening operation on the skate that is secured within the skate receiving slot, the operative unit being positioned over at least a portion of the base, the base comprising a swarf-receiving cavity, the operative unit and the base being pivotably connected.
Abstract:
The method is for profiling blades (406) with a belt (402) grinding profiling machine (400). The blades (406) are mounted into a vise (432). A vertical position of the template (404) is adjusted by rotating the rotatable knob (448). The motor (408) is turned on to rotate the grinding belt (402) over the grinding wheel (410). The guide wheel (424) engages the underside profile (420) of the template (404). The guide wheel (424) of the template (404) guides movement of the grinding wheel (414) mounted on the common axle by moving the guide wheel (424) along the underside profile (420) of the template (404). The grinding belt (402) grinds material off the underside of the blade (406) until a portion of the underside profile (420) of the template (404) is copied to the underside (422) of the blade (406).
Abstract:
A sharpening machine (2) for sharpening a scraping roller (4) for scraping the skin side of an animal pelt such as a mink pelt is disclosed. The scraping roller (4) comprises a plurality of teeth with edges (42), wherein the sharpening machine (2) comprises a sharpening member (52) provided with a sharpening structure (32) configured to sharpen an edge (42) of the scraping roller (4) in a manner in which the sharpening structure (32) sharpens the edge (42) by being moved in a direction (a) within a range of 60 degrees relative to the direction along the edge (42) towards the free end (E1, E2) of the scraping roller (4).
Abstract:
A method of removing material from a workpiece includes moving a coated abrasive over a receiving surface of a platen, the receiving surface having at least one opening configured for the flow of an ejection material therethrough, moving the platen and workpiece relative to each other to contact the coated abrasive to the workpiece and removing material from the workpiece, and controlling a flow pressure for the ejection material through the at least one opening during removing material from the workpiece, where the flow pressure of the ejection material can be adjusted based on at least one of the operation parameters such as a translation rate of the coated abrasive over the receiving surface, the weight of the coated abrasive, a material removal rate, a coefficient of friction between the coated abrasive and the platen, or a combination thereof.
