Bosko Hidraulika


When cylinders are manufactured or their internal surfaces are renewed, the friction between the touching elements (such as the piston and the cylinder) is decreased by a thin oil film. In order to keep this film in place, during the honing process, we etch helical grooves having dimensions in the micrometer range in the smooth surface that help in keeping oil in place. In addition, honing also ensures circularity and quality of the internal surface of the cylinder.

Our horizontal machine allows us to machine holes that are open at both ends, blind holes, shouldered holes, etc.
