摘要：The invention provides a method for the centerless grinding of shaft parts (9), inparticular of tubes for assembled camshafts, in the case of which the shaft part (9) whichis to be ground, and has axial centering portions (11) on its end sides, is ground inrotatably driven fashion, in a manner which is customary in centerless grinding, in a gapbetween the grinding wheel (1) and regulating wheel (2). The grinding wheel (1) andregulating wheel (2) have a width which corresponds at least to the length of the shaftpart (9). The shaft part (9) is ground in its end regions (28) first of all concentrically inrelation to the centering portions (11), and this produces ground formations

concentrically in relation to the centering portions (11). This is followed by the grindingof the intermediate region (29), which is located between the end regions (28), and thenby the entire shaft part (9) being ground to size in a dimensionally accurate anddimensionally stable manner on the basis of the ground formations at the end regions(28) of the shaft part (9), said formations being made concentrically in relation to the

centring portions (11) and resting on a support (16). In order to implement the method,the invention provides an appropriately dimensioned grinding-wheel and regulating-wheel pair (1, 2) in a centreless grinding machine, in the case of which regions of increaseddiameter, i.e. a respective profiling, are/is provided in the side regions of said machine inorder to grind the end regions (28) of the shaft part (9).
