Patent ID: 7101276

Claim:
An abrasive cutting-off wheel for stationary use, comprising an outside diameter (A); a total thickness (d); two interior supporting disks ( 1 , 1 ′), which are concentric of a joint central longitudinal axis ( 10 ), each of which have a periphery ( 3 , 3 ′) of an outside diameter (B); each of which have a thickness (a), and which are connected to each other; two interior layers of abrasive grain ( 4 , 4 ′), which are concentric of the central longitudinal axis ( 10 ), which have a thickness (a) that corresponds to the thickness (a) of the interior supporting disks ( 1 , 1 ′), which adjoin the periphery ( 3 , 3 ′) of the interior supporting disks ( 1 , 1 ′), and which have an outside diameter (A); two reinforcement layers ( 8 , 8 ′), which are concentric of the central longitudinal axis ( 10 ), each of which rests on the interior supporting disk ( 1 , 1 ′) and on the layer of abrasive grain ( 4 , 4 ′), which are united with the interior supporting disk ( 1 , 1 ′), and which have an outside diameter (A); two exterior supporting disks ( 11 , 11 ′), which are concentric of the central longitudinal axis ( 10 ), each of which have a periphery ( 12 , 12 ′) of an outside diameter (E), which are united with the respective reinforcement layer ( 8 , 8 ′), which have a thickness (c), and the outside diameter (E) of which is less than the outside diameter (B) of the interior supporting disks ( 1 , 1 ′); and two exterior layers of abrasive grain ( 13 , 13 ′), which are concentric of the central longitudinal axis ( 10 ), which have a thickness (b), which adjoin the periphery ( 12 , 12 ′) of the exterior supporting disks ( 11 , 11 ′), and which have an outside diameter (A).
