 a machine frame;   a plurality of guiding rollers rotatably mounted on said machine frame for manually shifting the rail grinding machine on rails;   a cross slide displaceably mounted on said machine frame in a transverse direction; and   at least one grinding unit interchangeably disposed at said cross slide.   
     
     
         2 . The rail grinding machine according to  claim 1 , wherein said at least one grinding unit is mounted on two sides. 
     
     
         3 . The rail grinding machine according to  claim 1 , which further comprises a quick-change device for interchangeably fastening said at least one grinding unit. 
     
     
         4 . The rail grinding machine according to  claim 3 , wherein said quick-change device includes at least one first quick-change element and at least one respectively associated second quick-change element, said first and second quick-change elements being reversibly connectable to one another in at least one of a form-locking or friction-locking manner. 
     
     
         5 . The rail grinding machine according to  claim 3 , wherein said quick-change device includes a first quick-change element, an associated second quick-change element and at least one actuating element for reversibly clamping said first quick-change element and said associated second quick-change element. 
     
     
         6 . The rail grinding machine according to  claim 3 , wherein said quick-change device configures at least one linear guide. 
     
     
         7 . The rail grinding machine according to  claim 1 , which further comprises a guide frame disposed at said cross slide. 
     
     
         8 . The rail grinding machine according to  claim 1 , which further comprises a guide frame swivel-mounted on said cross slide about a swivel axis running parallel to a longitudinal direction. 
     
     
         9 . The rail grinding machine according to  claim 6 , which further comprises a guide frame defining a plane, said at least one linear guide running transversely to said plane defined by said guide frame. 
     
     
         10 . The rail grinding machine according to  claim 1 , wherein said cross slide includes a closed cross slide frame. 
     
     
         11 . The rail grinding machine according to  claim 10 , wherein said closed cross slide frame bounds an inner space in which said at least one grinding unit is at least partially disposed. 
     
     
         12 . The rail grinding machine according to  claim 1 , which further comprises a guide frame, and a grinding unit carrier for interchangeably carrying said at least one grinding unit, said grinding unit carrier being mounted on said guide frame. 
     
     
         13 . The rail grinding machine according to  claim 7 , wherein said guide frame includes two guide elements, and two carrying elements are mounted on said two guide elements for carrying said at least one grinding unit. 
     
     
         14 . The rail grinding machine according to  claim 1 , wherein said at least one grinding unit includes a first grinding unit for profiling a rail and a second grinding unit for deburring a rail. 
     
     
         15 . The rail grinding machine according to  claim 1 , which further comprises a coarse positioning device for coarse positioning and a fine positioning device for fine positioning of said cross slide in the transverse direction. 
     
     
         16 . The rail grinding machine according to  claim 1 , wherein said at least one grinding unit includes a grinding tool drive having a combustion engine. 
     
     
         17 . A method for grinding rails of a track, the method comprising:
 providing a rail grinding machine having a first grinding unit;   grinding a rail of a track by using the first grinding unit;   exchanging the first grinding unit for a second grinding unit; and   grinding a rail by using the second grinding unit.   
     
     
         18 . The method according to  claim 17 , which further comprises:
 profiling the rail by using the first grinding unit; and   deburring the rail by using the second grinding unit.
