METHOD OF FINISHING ICE LINER INNER SURFACES

摘要

FIELD: process engineering.SUBSTANCE: invention relates to machine building, particularly to finishing of ICE liners. Liner inner surface is subjected to rough and semifinish honing to surface roughness Ra=1.15?2.35 mcm. Then, said surfaces is blasted by steel balls to roughness Ra?0.5 mcm, mean depth of recess R?1 mcm and relative reference length of profile t=85%.EFFECT: longer life.2 cl, 1 ex
