Process and apparatus for the clamping of a hollow cylindrical workpiece

摘要

A pipe body (6) to be divided into ring-shaped blanks (11) is pushed concentrically over a clamping mandrel (2) whose external diameter is smaller than the internal diameter of the pipe body, so that an annular gap (7) results between the two, which gap is filled with a pouring alloy (8), which expands on cooling, and thus clamps and fixes the pipe body for machining by cutting off. <IMAGE>
