Datong Hydraulic

Hydraulic Cylinder Tube ST52 and ST52.3 with excellent machinability and weldability. Supplied seamless or welded, cold drawn & stress relieved (BK+S), with yield strength over 520 MPa. The inside diameter is honed and oiled with the tube ends capped for Protection. TYPICAL APPLICATIONS: Hydraulic and pneumatic cylinders for mining, agricultural and farm machinery, hoists, automotive and transport lifting equipment, waste disposal transport, food processing equipment, mechanical tools and equipment, compressors and earth moving equipment etc.   MACHINABILITY: Excellent machinability in the BK+S (as supplied) condition WELDING: By any of the standard welding processes As a professional hydraulic cylinder tube manufacturer and supplier, Datong Hydraulic has been supplying and exporting honed tube for almost 20 years.

Skiving and roller burnishing tube  process provide high quality hydraulic cylinders with final sizing and creates the desired finish pattern on the interior of tubing or cylinder bores. They are used in the manufacturing of  hydraulic cylinders . Compared to honing process, they are 80-90% saving of machine time which reduces tool costs per meter of tube length and produces super finish surface, with a bore tolerance of IT8, thereby reduces the sealing wear making it ideal for pistons. The skiving tool is a multifunctional tool used in the manufacturing of hydraulic cylinders. Skiving is operated like this: Two thin chips are cut at a high feed rate (1-4 mm/rev) while the tool passes through the work piece. This cutting operation determines the finished diameter and tolerance of the hydraulic tube. Surface finish Ra= 4-10 μm (skiving) Skiving has obvious advantages compared with honing: • 80-90% saving of machine time which reduces tool costs per meter of tube length...
