摘要:
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.
摘要:
A composition that can be used for abrasive processing is disclosed. The composition includes an organic bond material, an abrasive material dispersed in the organic bond material, and a plurality of microfibers uniformly dispersed in the organic bond material. The microfibers are individual filaments having an average length of less than about 1000 μm. Abrasive articles made with the composition exhibit improved strength and impact resistance relative to non-reinforced abrasive tools, and improved wheel wear rate and G-ratio relative to conventional reinforced tools. Active fillers that interact with microfibers may be used to further abrasive process benefits.

摘要:
A fixed abrasive article having a body including abrasive particles contained within a bond material, the abrasive particles including shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, each of the shaped abrasive particles or elongated abrasive particles having a predetermined position or a predetermined three-axis orientation.
摘要:
An abrasive article including a substrate as an elongated member, a first layer overlying the substrate, abrasive particles overlying the first layer, fillets connecting the first layer and the abrasive particles, a bonding layer overlying the abrasive particles, the first layer and the fillets, and the fillets have a fillet characteristic relative to an abrasive application, the fillet characteristic selected from the group consisting of tacking factor (tfl/tf), a fillet-to-particle factor (tf/dab), a fillet-to-bonding layer factor (tf/tbl), a contact factor (Ab/Af), a fillet size variance (Vf), and a combination thereof.
摘要:
The present disclosure relates to abrasive aggregates comprised of abrasive particles in a vitreous binder composition, and methods of making and using such abrasive aggregates, including in abrasive articles. The abrasive aggregates can include modifier particles. The abrasive aggregates can include a layer of outer particles on at least a portion of the outer surface of the abrasive aggregate.
摘要:
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.
