Grinding plate for a grinding disk of a grinding machine and production method

Abstract

A grinding plate for a grinding disk of a grinding machine, wherein the grinding plate has a basic body and a Velcro hook layer with Velcro hooks. The basic body of the grinding plate includes a fiber-reinforced plastic and the Velcro hook layer comprises a nonreinforced plastic. A method for producing such a grinding plate is also provided. The Velcro hook layer can be molded as a thin layer of nonreinforced plastic onto the basic body made of a fiber-reinforced plastic. The grinding plate can be produced in particular in a two-component injection molding method.

         25 . The grinding plate as recited in  claim 16  wherein the Velcro hooks have a width in a range from 0.05 to 5 mm. 
     
     
         26 . The grinding plate as recited in  claim 25  wherein the Velcro hooks have a width in a range from 0.1 to 0.3 mm 
     
     
         27 . The grinding plate as recited in  claim 26  wherein the Velcro hooks have a width of 0.2 mm. 
     
     
         28 . The grinding plate as recited in  claim 16  wherein the Velcro hooks are arranged in radial rows, and the Velcro hooks of the radial rows are oriented in an alternating manner in the clockwise direction and in the counterclockwise direction. 
     
     
         29 . The grinding plate as recited in  claim 28  wherein the radial rows have a spacing in a range from 0.3 to 2 mm. 
     
     
         30 . The grinding plate as recited in  claim 29  wherein the radial rows have a spacing in a range in a range from 0.5 to 1.5 mm. 
     
     
         31 . The grinding plate as recited in  claim 30  wherein the radial rows have a spacing in a range in a range from 0.7 to 1.0 mm. 
     
     
         32 . The grinding plate as recited in  claim 31  wherein the radial rows have a spacing of 0.8 mm. 
     
     
         33 . The grinding plate as recited in  claim 16  wherein the Velcro hook layer has a total thickness in a range from 0.3 to 3 mm. 
     
     
         34 . The grinding plate as recited in  claim 33  wherein the Velcro hook layer has a total thickness in a range from 0.5 to 2 mm. 
     
     
         35 . The grinding plate as recited in  claim 34  wherein the Velcro hook layer has a total thickness in a range from 0.8 to 1.5 mm. 
     
     
         36 . The grinding plate as recited in  claim 35  wherein the Velcro hook layer has a total thickness of 1 mm. 
     
     
         37 . A method for producing a grinding plate as recited in  claim 16 , the method comprising the following steps:
 a) producing the basic body including the fiber-reinforced plastic,   b) attaching the Velcro hook layer including the non-reinforced plastic and the Velcro jooks to a surface of the basic body.
