Systems and methods for forming semiconductor cutting/trimming blades
A dressing board for sharpening and/or shaping blades for manufacture of semiconductor devices can include a working surface configured to sharpen and/or shape a cutting surface of a dicing or edging blade for manufacture of a semiconductor device. The working surface can be configured to contact the cutting surface of the blade when sharpening or shaping the cutting surface. The dressing board can include a support substrate configured to support the working surface with respect to a floor of an enclosure in which the dressing board is positioned. In some embodiments, the working surface includes a first portion that is not parallel to the floor.

DYNAMIC REGULATION OF CONTACT PRESSURES IN A BLADE SHARPENING SYSTEM
Dynamic regulation of contact pressures in a blade sharpening system is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply dynamic cushioning and processor-controlled contact pressure between the grinding wheels and the cutting blade during sharpening. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components.

WHETTING DEVICE FOR A SLICER COMPRISING A GUARD PREVENTING ACCIDENTAL CONTACT DURING MOUNTING
A whetting device for a slicer has a whetstone for sharpening a circular blade of the slicer; a hone for deburring the blade; a handle for moving the whetstone or hone toward the blade; a mount fastenable to a stop plate of the slicer, having an insertion apparatus for form-fittingly insertion into the stop plate, a U-shaped plate receptacle which has a gap for introducing the stop plate into the gap when the whetting device is pushed onto the stop plate; a receptacle for engaging around an end of the blade guard ring when the stop plate is a predetermined distance from the circular in the direction of rotation of the blade, and not to engage when shorter than that distance between; and a frame covering a cutting edge of the circular blade and for pivoting the whetting device into a working position.
CUTTING MACHINE FOR PRODUCTS MADE OF CELLULOSE MATERIAL AND RELATED METHOD
The machine includes a feed channel of a product to be cut and members for feeding the product along the feed channel. A cutting blade is provided to cut the products into articles according to cutting planes orthogonal to a longitudinal direction of the products and a sharpening unit is provided to sharpen the cutting blade. The machine further includes an adjustment system that receives in input at least one information on the operation of the cutting machine and provides, in response to the information, an adjustment command of the cutting machine.
Gin Blade Sharpening System and Method of Use
A prior art grinding assembly a gin blade sharpening system for sharpening a blank into a blade disk. The gin blade sharpening system comprises two or more grinding stations, a controller, and one or more upper grinders. The one or more upper grinders comprise at least a first upper grinder. The two or more grinding stations comprise at least a first grinding station and a second grinding station. each among the two or more grinding stations comprise a clamp assembly configured to selectively hold the blade disk in a substantially horizontal position. a portion of the one or more upper grinders can be configured to sharpen an outer perimeter edge of the blade disk using an abrasive pad.
