The Boring-grinding-rolling Techniques for Hydraulic Cylinder of 0.2 Carbon Steel

摘要

The internal surface processing of hydraulic cylinder requires high accuracy of size, shape, and good deformed surface finish. When the cylinder is made of 0.2% carbon steel, it is rather difficult to meet the design requirements in boring-rolling operations because of its material properties. This paper discussed the boring-grinding-rolling techniques and presented the recommended process parameters through experimental studies on a reequipped lathe.
