    摘要: In one aspect, a process for roll grinding employs a grinding wheel that is porous and permeable. In another aspect, a process for grinding mill rolls includes dressing the grinding wheel as the wheel traverses the surface of a mill roll. Other aspects relate to a system, e.g., a mill roll grinding machine, or parts thereof, in which a dressing tool contacts the wheel as the wheel grinds the surface of the mill roll. In specific examples, the wheel and a rotary dressing tool are maintained in contact as the wheel traverses the surface of the mill roll.

    摘要: An abrasive product includes a plurality of abrasive particles and a resin binder cured from a resin composition that includes an aqueous dispersion of melamine methylol having a melamine-to-formaldehyde molar equivalent ratio of between about 1:1 and about 1:3.2, wherein the aqueous dispersion has a pH in a range of between about 8 and about 10. The composition also includes a formaldehyde-based resins, such as a urea-formaldehyde resin or phenol-formaldehyde resin. The melamine methylol comprises between about 1 wt% and about 50 wt% of the combined weight of the formaldehyde-based resin and the melamine methylol.

    摘要: Mating systems and methods for joining coated abrasives. The mating system (100) comprises mating portions (130, 140) positioned at coated abrasive end portions (110, 120). Complimentary mating portions may be used to join coated abrasives without glue or mechanical attachment. The mating system of the present invention may be used to join a coated abrasive to itself, or to join multiple coated abrasives to each other.
