Grinding Machine

Abstract

The present invention comprises a grinding machine for grinding a metallic surface of a workpiece, wherein the grinding machine has at least one grinding apparatus, at least one transport belt ( 2 ) for transporting the workpiece through the grinding machine, and at least one suction device by means of which a workpiece lying on the transport belt ( 2 ) can be acted on with a negative pressure, wherein the suction device has an extraction chamber ( 14 ) which is arranged below the transport belt ( 2 ) and which has a base ( 16 ) which is inclined with respect to the horizontal.

1 . A grinding machine for grinding a metallic surface of a workpiece, comprising:
 at least one grinding apparatus;   at least one transport belt for transporting the workpiece through the grinding machine; and   
       an extraction chamber which has a base which is inclined with respect to horizontal, wherein the extraction chamber is oriented below the at least one transport belt. 
     
     
         2 . The grinding machine according to  claim 1 , further comprising at least one suction device by means of which a workpiece lying on the at least one transport belt can be acted on with a negative pressure, wherein the extraction chamber is part of the at least one suction device. 
     
     
         3 . The grinding machine according to  claim 1 , wherein the base of the extraction chamber encloses an angle of 5° to 30°, with the horizontal. 
     
     
         4 . The grinding machine according to  claim 1 , wherein the base of the extraction chamber is inclined in a direction perpendicular to a transport direction along which the workpiece is transported by the at least one transport belt. 
     
     
         5 . The grinding machine according to  claim 1  wherein the extraction chamber is connectable, at a lower end of the base to a suction device. 
     
     
         6 . The grinding machine according to  claim 1  wherein the at least one transport belt is coated with an anti-adhesion coating. 
     
     
         7 . The grinding machine according to  claim 1  wherein at least one of an inner side of the extraction chamber and the base of the extraction chamber is coated with an anti-adhesion coating. 
     
     
         8 . The grinding machine according to  claim 6  wherein the anti-adhesion coating is comprised of one or more polymers. 
     
     
         9 . The grinding machine according to  claim 1  wherein the at least one transport belt includes multiple transport belts, and further comprising multiple suction devices, wherein each of the multiple suction devices has an extraction chamber with an inclined base. 
     
     
         10 . The grinding machine according to  claim 1  wherein the at least one transport belt is exchangeable without requiring the at least one grinding apparatus to be removed. 
     
     
         11 . The grinding machine according to  claim 7  wherein the anti-adhesion coating is comprised of one or more polymers.
