Uses: used for a paving engineering machinery compaction paver (also called vibratory roller, roller, paver, etc.) products, through the eccentric circle to drive the vibration component to achieve the hammer bar up and down rapid vibration compaction of the road surface;

Features: It is a high-precision, high-strength shaft part with an eccentric circle. The shaft has a coaxial installation circle (used to install bearings, oil seals, installation to the mounting seat, etc.) and an eccentric circle, excircle roundness and cylindricity, The requirements for items such as size, roughness, and eccentric circle position are very high.
Process requirements: the blank is generally made of steel bars or forgings, the main processes include: roughing-heat treatment-semi-finishing-grinding and other processes; the main processing equipment is CNC lathe, CNC cylindrical grinder, quenching equipment and other equipment.
Key testing items: surface roughness, roundness, cylindricity, coaxiality, hardness, metallographic and other items; Key testing equipment: large and medium-sized precision coordinate measuring machines, hardness testers, metallographic microscopes and other high-precision testing equipment.
