Method of operating a gearwheel machining tool

A method of operating a gearwheel machining tool having a machining wheel disposed on a drive axis, which comprises the steps of:

• placing a gearwheel to be machined at a fixed axial distance from the machining wheel, at least during engagement and/or disengagement of the gearwheel to be machined onto or from an arbor, the fixed axial distance being less than a sum of two tip circle radii and being greater than a sum of one tip circle radius of one of the machining wheel and the gearwheel and one root circle radius of the other of the machining wheel and the gearwheel;
• and
• placing the gearwheel to be machined at an arbitrary rotational angle position on the arbor, tooth areas of the gearwheel lateral external surface facing toward the machining wheel coming to rest on lateral tooth areas of the machining wheel, upon which the machining wheel being set into rotation or already rotates and the gearwheel to be machined slides axially on the arbor into a machining position, after which tooth gaps of two overlapping areas of the gearwheel and the machining wheel are rotated one over the other and the gearwheel and the machining wheel mutually come into engagement, upon which the gearwheel to be machined is fixed on the arbor and actual machining begins.
