Deformation of billet and peripheral slip between rolls and billet during the Mannesmann piercing process were investigated. A billet, on whose surface a fine line mark is scraped paralled to its axis, was pierced or stopped on the way of piercing, and then twist of the fine mark was measured. From the results of this experiment and of the first report, we could calculate the peripheral slip. Results obtained are as follows : (1) Twist of pierced billet surface is much less than the calculated value, as peripheral slip exists. (2) Peripheral slip is maximum in the centre of pass and far less than axial slip as seen in the following table. [table]
