Abstract:
A milling machine fine precision adjustor of a quill relative to an object for milling, comprising:a first rotatable component capable of being attached to a shaft of a milling machine, wherein the milling machine shaft is manually rotated to move said shaft in a substantially vertical direction via a first manual quill adjustor, to move said quill relative to the object to be milled;a second rotatable component having an axis of rotation different from that of said first rotatable component, wherein said first and second rotatable components are operably connected so that a full rotation of said second rotatable component causes less than a full rotation of said first rotatable component;a second manual quill adjustor operably connected to said second rotatable component for rotating said second rotatable component;wherein after an operator of the milling machine manually moves the first manual quill adjustor to an approximation of a desired position of the quill, the operator is capable of moving said second manual quill adjustor for providing a more precise positioning of the quill relative to the object.
