Abstract:
This invention relates to compressed composite backing materials (e.g., compressed polymer impregnated backing substrates) and coated abrasive articles that include such compressed composite backing materials. This invention also relates to methods of making and using said compressed composite backing materials and coated abrasive articles. The claimed processes and systems related to the use and manufacturing of coated abrasive articles are improved and cost effective.
Abstract:
A grinding tool includes a shank having an axis, and at least two abrasive portions mounted directly to and in contact with the shank without a hub therebetween. Each of the abrasive portions has a substantially identical profile formed therein.
Abstract:
An abrasive article can include a body including a bond material and abrasive particles contained within the bond material. The abrasive particles can include nanocrystalline alumina. The bond material can include an inorganic material including a ceramic.
Abstract:
This invention relates to abrasive flap wheel that include hybrid fabrics. This invention also relates to methods of making and using said abrasive flap wheels. The claimed processes and systems related to the use and manufacturing of abrasive flaps are improved and cost effective.
Abstract:
A containment tube includes a sealed tube comprising silicon carbide, first and second ends, an inner bore extending along at least a portion of its axial length between the first and second ends, and contains a radioactive material within the bore of the sealed tube. The first end has a plug residing in the inner bore to close the first end, and the second end has a distal wall that closes the inner bore at the second. At least one of the first or second ends is bonded to the sealed tube by a sinter bond.
Abstract:
An abrasive article including a body including a bond material having an inorganic material including a ceramic, abrasive agglomerates including silicon carbide contained within the bond material, and a permeability of at least 60.
Abstract:
An abrasive article including a substrate having an elongated body, a tacking layer overlying the substrate, and a first type of abrasive particle overlying the tacking layer and defining a first abrasive particle concentration at least about 10 particles per mm of substrate.
Abstract:
An abrasive article includes a body having abrasive grains contained within a bond material comprising a metal or metal alloy, wherein the body comprises a ratio of VAG/VBM of at least about 1.3, wherein VAG is the volume percent of abrasive grains within the total volume of the body and VBM is the volume percent of bond material within the total volume of the body.
Abstract:
An abrasive article including a core including an organic material and a first bonded abrasive body integrally bonded directly to the core, the first bonded abrasive body having abrasive particles contained within a bond material and the abrasive article having a bonding factor of at least about 60%.
Abstract:
A button for attaching an abrasive article to a back-up pad can include a body having a lower plate, and a hub extending from the lower plate. The hub is configured to engage an abrasive article installed over the hub at least partially along the height of the hub to prevent the abrasive article from rotating relative to the hub. The body can also include a post extending from the hub. The post can include at least one helical thread extending outwardly along the post. Further, the post can include a height, HP, and the at least one helical thread includes a thread lead, L, that is ≧0.5 HP.
