Honing process is a precision surface treatment made to achieve sealing elements work in high performance by increasing the surface quality of the inside of the tube by abrasion. Besides, helical traces on the surface help to minimize friction by assisting the formation of the lubricating film.

Atlas Hydraulic has a honing capacity of 50-400 mm inside diameter and 4000 mm length. The surface quality obtained after the process is Ra 0,1-0,3 µ.
