Abrasive segment for an abrasive roll, grinding machine, and use

Abstract

An abrasive segment includes a carrier body for attaching the abrasive segment to a lateral surface of an abrasive roll in an interlocking manner; and a substantially planar abrasive layer. The abrasive layer is oriented substantially parallel to the lateral surface of the abrasive roll in a state of the abrasive segment in which it is attached to the abrasive roll, and an elastic intermediate layer is located between the carrier body and the abrasive layer.

         10 . The grinding roller as set forth in  claim 9 , wherein the peripheral surface is provided with at least one groove for receiving at least one abrasive segment, preferably wherein the at least one groove is of a substantially dovetail-shaped configuration and the at least one abrasive segment is positively lockingly fixed therein. 
     
     
         11 . The grinding roller as set forth in  claim 10 , wherein the at least one groove is arranged inclinedly relative to a longitudinal direction of the grinding roller, preferably at an angle between 1° and 10°, particularly preferably at an angle between 2° and 3.5°. 
     
     
         12 . The grinding roller as set forth in  claim 1 , wherein arranged at at least one end of the substantially cylindrical main body is at least one preferably substantially cylindrical opening for at least one tool receiving means, preferably wherein precisely two openings are arranged at the at least one end. 
     
     
         13 . The grinding roller as set forth in  claim 9 , wherein at least one locking mechanism, at least one cover and at least one opening, wherein the opening is arranged in the at least one cover and the at least one locking mechanism can be introduced into the at least one opening, for arresting the at least one abrasive segment are arranged at at least one of the ends of the substantially cylindrical main body. 
     
     
         14 . A grinding machine comprising the grinding roller as set forth in  claim 9  and at least one rotary drive with which the grinding roller can be set in rotation to cause a relative movement of the at least one abrasive layer relative to the surface to be machined of the workpiece or the negative form. 
     
     
         15 . The grinding machining as set forth in  claim 14 , wherein there is provided at least one handle, preferably provided with at least one grinding fluid feed means, for manual guidance of the grinding machine.
