Grinding wheel assembly

Abstract

A grinding wheel assembly is disclosed and includes an arbor in which a pull stud may be installed. Further, the arbor can include a head assembly that includes a mounting plate, a cover plate, and an abrasive body disposed there between. The abrasive is removably engaged with the mounting plate and the cover plate.

What is claimed is: 
     
         1 . An abrasive article comprising:
 a body including:
 a mounting plate; and 
 a cover plate, wherein the mounting plate and cover plate are configured to be coupled to each other and form a head assembly including a channel region disposed between the mounting plate and the cover plate, wherein the head assembly further comprises a rotation limiting structure adjacent to the channel region, the rotation limiting structure configured to engage an abrasive body and prevent rotation of the abrasive body relative to the head assembly. 
   
     
     
         2 . The abrasive article of  claim 1 , wherein the mounting plate comprises a generally cylindrical mounting hub extending axially from a contact surface of the mounting plate, the contact surface of the mounting plate configured to engage a portion of the abrasive body and the mounting hub configured to receive the abrasive body there around. 
     
     
         3 . The abrasive article of  claim 1 , wherein the rotation limiting structure comprises a notch extending radially inwardly from a mounting hub of the mounting plate. 
     
     
         4 . The abrasive article of  claim 3 , wherein the rotation limiting structure further comprises a tab extending radially inward from the abrasive body, wherein the tab is configured to extend at least partially into and engage the notch formed in the mounting plate. 
     
     
         5 . The abrasive article of  claim 1 , wherein the rotation limiting structure comprises a notch extending radially into an inner wall of a backing of the abrasive body. 
     
     
         6 . The abrasive article of  claim 5 , wherein the notch comprises a depth, D, and the backing comprises a wall thickness, TW, and wherein D is less than TW. 
     
     
         7 . The abrasive article of  claim 6 , wherein D is less than 50% TW. 
     
     
         8 . The abrasive article of  claim 1 , wherein the cover plate, the mounting plate, or both comprises a metal or metal alloy. 
     
     
         9 . An abrasive article, comprising:
 a body including:
 a mounting plate; and 
 a cover plate, wherein the mounting plate and cover plate are configured to be coupled to each other and form a head assembly including a channel region disposed between the mounting plate and the cover plate; 
 an abrasive body disposed between the mounting plate and the cover plate comprising:
 a backing; 
 an abrasive portion affixed to the backing, wherein the backing includes at least one rotation limiting feature configured to engage a complimentary rotation limiting structure on a mounting plate of a grinding wheel assembly. 
 
   
     
     
         10 . The abrasive article of  claim 9 , wherein the backing comprises a metal or a metal alloy. 
     
     
         11 . The abrasive article of  claim 9 , wherein the backing comprises bronze. 
     
     
         12 . The abrasive article of  claim 9 , wherein the backing comprises a composite material. 
     
     
         13 . The abrasive article of  claim 9 , wherein the abrasive portion is brazed to the backing, sinter-bonded to the backing, or adhered to the backing. 
     
     
         14 . The abrasive article of  claim 9 , wherein the backing has a hardness, HB, and the cover plate has a hardness, HCP, and HB is less than HCP. 
     
     
         15 . The abrasive article of  claim 9 , wherein the abrasive portion has a thickness, TA, and the backing has a thickness, TB, and TB is greater than TA. 
     
     
         16 . An abrasive article comprising:
 a body including:
 a mounting plate; and 
 a cover plate, wherein the mounting plate and cover plate are configured to be coupled to each other and form a head assembly including a channel region disposed between the mounting plate and the cover plate, wherein the head assembly further comprises a vibration dampening member adjacent to the mounting plate or the cover plate, the vibration dampening member configured to reduce vibration of an abrasive body installed within the channel region. 
   
     
     
         17 . The abrasive article of  claim 16 , wherein the vibration dampening member comprises at least one material selected from the group consisting of an organic material, an inorganic material, a metal, a metal alloy, a ceramic, a glass, a thermoset, a thermoplastic, an elastomer, or any combination thereof. 
     
     
         18 . The abrasive article of  claim 16 , wherein the vibration dampening material comprises a polymer material. 
     
     
         19 . The abrasive article of  claim 18 , wherein the polymer comprises polyamid. 
     
     
         20 . The abrasive article of  claim 16 , further comprising an abrasive body disposed within the channel region between the mounting plate and the cover plate.
