Skiving and roller burnishing steel tubes made mainly for the hydraulic cylinder industry and other applications where fine-finishing of the internal diameter of a tube is required, Primarily for hydraulics in the contracting, mining and construction industries.
Skiving has some preference over honing , for example, skiving can increase the tube ID surface hardness obviously, providing better tolerance and better surface finishing, achieving Ra0.05--0.3max, also reducing the ovality of CDS tube .
Comparing with surface of honed tube, the skived and burnished surface provides longer seal life because of its better wear --resistance property . For the advantage of its reliability, wear-resistance and operating reliability, its coming more widely adopted by cylinder manufacturing industry ,Like Caterpillar, Komatsu, SANY, XuGong, Wirpo India, Zoomlion, etc.Surface roughness:
The surface roughness is Ra 0.05--0,3μm.
Tolerances In accordance with DIN 2391/2393. H8/H9.
cylinder tube is delivered as standard in cold drawn stress relieved condition.(BKS&SR).
Tube dimension :
Roller burnished tubes are available in a wide range of sizes from OD 50 – 300 mm and ID 40 – 250 mm , length: 50---9000mm.
