1. A system for ablating material in vein grafts includes an ablation burr that is rotated by a driveshaft.

2. A vehicle's Axle ratio is the number of rotations its driveshaft must make to produce one rotation of the Axle

3. The invention proposes a gearbox pump (1), in particular a gearbox oil pump of an automatic gearbox of a motor vehicle, which comprises a pump housing (2) and a pump cover (3) or oil-guiding flange and in the case of which, for a gear pump, the driving pump gear (6) or, for a vane pump, the rotor is driven via a pump driver (5) operatively connected to the pump driveshaft (4), wherein the pump-driver surfaces are inclined such that the driving pump gear (6) is routed axially in the direction of the pump housing (2) and ends up in abutment against the pump housing (2).
