Apparatus for the lapping or testing of gears (T, R), with at least five axis, with - a first spindle group for chucking a first gear (T), whereby the first gear (T) is mountable on the first spindle group so that it is rotatable about a first axis of rotation (TA), - a second spindle group for chucking a second gear (R), whereby the second gear (R) is mountable on the second spindle group so that it is rotatable about a second axis of rotation (RA), - a first linear axis (LA1) for carrying out a first linear displacement of the first spindle group with the first gear (T) relative to the second spindle group with the second gear (R), and - with a second linear axis (LA2) for carrying out a second linear displacement of the first spindle group with the first gear (T) relative to the second spindle group with the second gear (R), characterized - in that the apparatus further comprises a swivel axis (SA) for pivoting the first spindle group with the first gear (T), which swivel axis (SA) being parallel to the second axis of rotation (RA), or - in that the apparatus further comprises a swivel axis (SA) for pivoting the second spindle group with the second gear (R) about this swivel axis (SA) which swivel axis (SA) being parallel to the first axis of rotation (TA), or - in that the apparatus further comprises a first swivel axis (SA) for pivoting the first spindle group with the first gear (T) as well as a second swivel axis for pivoting the second spindle group with the second gear (R) about this second swivel axis, wherein both spindle groups (111; 112) can be pivoted by 90 degrees such that the first axis of rotation (TA) and the second axis of rotation (RA) run parallel to one another and are perpendicular to a horizontal plane (E). - a first spindle group for chucking a first gear (T), whereby the first gear (T) is mountable on the first spindle group so that it is rotatable about a first axis of rotation (TA), - a second spindle group for chucking a second gear (R), whereby the second gear (R) is mountable on the second spindle group so that it is rotatable about a second axis of rotation (RA), - a first linear axis (LA1) for carrying out a first linear displacement of the first spindle group with the first gear (T) relative to the second spindle group with the second gear (R), and - with a second linear axis (LA2) for carrying out a second linear displacement of the first spindle group with the first gear (T) relative to the second spindle group with the second gear (R), characterized - in that the apparatus further comprises a swivel axis (SA) for pivoting the first spindle group with the first gear (T), which swivel axis (SA) being parallel to the second axis of rotation (RA), or - in that the apparatus further comprises a swivel axis (SA) for pivoting the second spindle group with the second gear (R) about this swivel axis (SA) which swivel axis (SA) being parallel to the first axis of rotation (TA), or - in that the apparatus further comprises a first swivel axis (SA) for pivoting the first spindle group with the first gear (T) as well as a second swivel axis for pivoting the second spindle group with the second gear (R) about this second swivel axis, wherein both spindle groups (111; 112) can be pivoted by 90 degrees such that the first axis of rotation (TA) and the second axis of rotation (RA) run parallel to one another and are perpendicular to a horizontal plane (E). <EOS>
