A procedure for machining the spiral-shaped rotor of a spiral pump, wherein the rotor blank is machined with a tool revolving in a circle around it, said circle being eccentrically positioned in relation to the axis of the rotor blank. Machining is then accomplished by rotating the rotor blank about its longitudinal axis and moving the tool in the direction of the rotor blank's axis relative to the rotor blank. Apparatus for machining the spiral-shaped rotor of a spiral pump, said apparatus comprising a frame (1) with spindles (2) for fixing the rotor blank (3) which shall be machined, a slide (4) movable in the direction of the rotor blank's axis, a power means (5) connected to the slide and to the spindle for moving the slide and rotating the spindle simultaneously and controlledly relative to each other, and on the slide an annular machining rest (6) provided with at least one machining tool (8) and eccentric with reference to the longitudinal axis of the rotor blank, the rotor blank being arranged to pass through this machining rest as the rotor blank is being rotated and the slide is being moved. |
