本文主要介绍盾构油缸精加工中成功应用的双轮浮动滚压工艺。盾构各种规格的油缸有■160、■350、■355mm 三种规格,长为1700～1883mm,材料为35和40cr 调质钢二种,各项精度均在0.05mm 以内,表面粗糙度,加工技术难度很高,为确保达到上述表面粗糙度,我们在油缸深孔精加工中成功地应用了双轮浮动滚压工艺,取得了良好的效果。 This article mainly introduces the two-wheel floating rolling process successfully applied in the shield cylinder finishing. Shield a variety of fuel tanks are ■ 160, ■ 350, ■ 355mm three specifications, length of 1700 ~ 1883mm, material 35 and 40cr quenched and tempered steel two, the accuracy are within 0.05mm, the surface roughness, In order to ensure the above-mentioned surface roughness, we have successfully applied the double-roller floating rolling process in the deep-hole finishing of the cylinder and achieved good results.
