Abstract
The invention relates to a quill for coordinate measuring machines of square cross-section and guided by a total of eight bearing parts within a guiding part. Three bearing parts which bear against quill surfaces are located adjacent the upper and in the lower ends of the guide surfaces in the guiding part. Two more bearing parts are provided in a Z direction approximately between the upper and lower bearing parts. Due to the special configuration of the bearing parts relative to each other and the horizontally acting springs inserted in certain bearing parts the twisting of the quill is determined and also the specified quill twisting accuracy of two angular seconds max. is obtained.
