Stabilizing the dimensions of long cast-iron parts by static reloading

  • 16 Accesses

Conclusions

  1. 1.

    Stress relaxation during static reloading of long cast-iron parts (up to 12 m) of heavy cylinderand-cone grinders of elevated and high accuracy is an effective means of stabilizing the dimensions of these parts.

  2. 2.

    Static loading is repeated three to six times, each lasting 1–3 min, until residual deformation ceases. The rapidity of the process in combination with mechanization of auxiliary work on a bench leads to high productivity.
