Grinding and/or Polishing Pad Device, Grinding and/or Polishing Machine, and Method for Manufacturing a Grinding and/or Polishing Pad Device

Abstract

A grinding and/or polishing pad device for a grinding and/or polishing machine with a carrier unit is disclosed. The carrier unit on the machine side has at least one air duct, in particular an exhaust air duct, which runs transversely with respect to a main normal of the carrier unit.

What is claimed is: 
     
         1 . A grinding and/or polishing pad device for a grinding and/or polishing machine, comprising a carrier unit, wherein:
 the carrier unit has, on the machine side, at least one air duct which extends transversely with respect to a main normal of the carrier unit.   
     
     
         2 . The grinding and/or polishing pad device according to  claim 1 , wherein the air duct extends at least substantially radially with respect to the main normal. 
     
     
         3 . The grinding and/or polishing pad device according to  claim 1 , further comprising a cover unit which is arranged on the carrier unit on the machine side and which is configured to at least partially delimit and/or close the air duct on the machine side. 
     
     
         4 . The grinding and/or polishing pad device according to  claim 3 , wherein the cover unit has at least one recess which defines an air passage opening for the air duct on the machine side, with an opening cross-section which runs at least substantially parallel to a main extension plane of the carrier unit. 
     
     
         5 . The grinding and/or polishing pad device according to  claim 1 , wherein the carrier unit has, on the machining side, at least one ribbed structural element which extends at least substantially radially straight with respect to the main normal. 
     
     
         6 . The grinding and/or polishing pad device according to  claim 5 , wherein the ribbed structural element is configured to form a side wall of the air duct. 
     
     
         7 . The grinding and/or polishing pad device according to  claim 5 , wherein the ribbed structural element protrudes on a machining side of the carrier unit in a direction parallel to the main normal of the carrier unit beyond the air duct. 
     
     
         8 . The grinding and/or polishing pad device according to  claim 1 , further comprising a cushioning unit which is foamed onto the carrier unit on the machining side relative to the carrier unit. 
     
     
         9 . The grinding and/or polishing pad device according to  claim 1 , further comprising a chain wheel-like drive interface unit, wherein the carrier unit has an air passage opening connected to the air duct which is arranged between two adjacent teeth of the chain wheel-like drive interface unit. 
     
     
         10 . The grinding and/or polishing pad device according to  claim 1 , further comprising a cushioning unit arranged on the carrier unit, the end face of which has, along a circumferential direction, recesses spaced apart from one another, different from openings. 
     
     
         11 . The grinding and/or polishing pad device according to  claim 10 , wherein a recessed region defined by the recesses along the circumferential direction extends over at least 10% of a maximum circumferential extension of the end face in the circumferential direction. 
     
     
         12 . The grinding and/or polishing machine having the grinding and/or polishing pad device according to  claim 1 . 
     
     
         13 . A method for manufacturing a grinding and/or polishing pad device according to  claim 1 , comprising:
 producing an air duct extending transversely to a main normal of a carrier unit in the carrier unit via injection molding; and   foaming a cushioning unit onto the carrier unit on the machining side so that a ribbed structural element of the carrier unit forms a side wall of the air duct and/or a drive interface unit is at least partially integrated into the carrier unit.   
     
     
         14 . The grinding and/or polishing pad device according to  claim 1 , wherein the at least one air duct is an exhaust air duct. 
     
     
         15 . The grinding and/or polishing pad device according to  claim 1 , wherein:
 the carrier unit has ribbed structural elements which each extend at least substantially radially straight with respect to the main normal, and   the ribbed structural elements form side walls of all air ducts.   
     
     
         16 . The grinding and/or polishing pad device according to  claim 1 , further comprising a cushioning unit arranged on the carrier unit, the end face of which has, along a circumferential direction, recesses spaced apart from one another, different from material-free sections.
