A grinding wheel is a wheel composed of an abrasive compound and used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines. The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding wheel terminology) to form a solid, circular shape. Various profiles and cross sections are available depending on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with particles bonded to the surface. Today most grinding wheels are artificial composites made with artificial aggregates, but the history of grinding wheels began with natural composite stones, such as those used for millstones.
Reinforced Bonded Abrasive Tools
InactiveUS20100190424A1Improve performanceReduce the amount requiredPigmenting treatmentRevolution surface grinding machinesFiberFiberglass mesh
Bonded abrasive tools, e.g., grinding wheels, can be reinforced using, for instance, one or more fibreglass web(s) having a surface of glass per unit of at least 0.2. Alternatively or in addition, the fibreglass web has a thickness of 2 mm or less. The web can be designed to provide improved adhesion between the fibreglass reinforcement and the mixture employed to form the bonded abrasive tool. In some examples, the middle reinforcement at the neutral zone of the wheel can be eliminated or minimized.

An electrolytic in-process dressing device 10 is provided with a disk-shaped metal-bonded grindstone 2 with a surface 2a with a circular arc shape with a radius R at its outer periphery and a numerical control device 16. The disk-shaped metal-bonded grindstone 2 rotates around an axis Y, and the grindstone is dressed electrolytically while the device 10 grinds the workpiece 1. The numerical control device 16 is provided with a rotary truing device 12 that rotates around the X axis that orthogonally crosses the axis of rotation Y and trues the circular arc surface 2a, a shape measuring device 14 for measuring the shape of the circular arc surface of the grindstone and the shape of the processed surface of workpiece 1 on the machine, and controls the grindstone numerically in the three directions along the axes X, Y and Z. The numerical control device 16 moves the grindstone in three axial directions and repeats the operations of truing, grinding and measurements on-line. Thus, an axially asymmetrical aspheric mirror with a highly accurate shape and extremely low surface roughness, that can precisely reflect or converge light can be manufactured within a short time with a high accuracy.

Methods and systems are disclosed whereby the edges of a glass sheet may be beveled with minimal equipment down time. Preferably such methods and systems bevel the upper and lower edges along lateral sides of a glass sheet. In especially preferred embodiments, laterally separated pairs of upper and lower edge grinding assemblies are provided having respective upper and lower oppositely oriented tapered grinding wheels. A glass sheet may thus be moved in a generally horizontal conveyance direction between one of these pairs of upper and lower edge grinding assemblies so that respective upper or lower lateral edges of the glass sheet are brought into grinding contact therewith. Continually moving the glass sheet in the horizontal conveyance direction will therefore present the other lateral edge to the other pair of upper or lower edge grinding assemblies positioned downstream. As such, the other edge will then be beveled. By independently mounting the oppositely oriented grinding wheels for independent movements both horizontally and vertically relative to the glass sheet, a fresh unscored region of the tapered grinding surfaces can then be presented to the glass sheet edges thereby ensuring that the proper bevel angle is achieved.
