The floating blocks with two cutting tools having cutting inserts placed opposite to one another are used when turning inner and outer long cylindrical surfaces. The article presents a theoretical research of the influence of the axial displacement of the cutting inserts and the stability of the floating block on precision of machining with variation of the depth of insertion. Obtained are dependencies for quantitative assessment of this influence as well as conditions for reducing it.
