  Skiving and roller burnishing   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 H8, thereby reduces the sealing wear making it ideal for pistons. It is capable of holding bore diameter tolerances to 0.025 mm (0.001 in.) The necessary equipment requires a large up-front investment, which makes it suitable for high-volume tubing production. The skiving and roller-burnishing operation, as the name implies, actually involves two processes in one tool. The tube is end clamped in the machine and the tool advances inside. Coolant is pumped through the ID of the tube, flows around the tool and pushes chips out of the front of ...

  Chrome plated OD tubing   is also called chrome plated   hollow bar . Production with internal no honed and external chrome plated tubes, Chrome plated OD tubing usually made from grades ST52 and ST52.3 Drawn Over Mandrel (DOM) steel tubing and  seamless cold drawn tube . Chrome plated tubing is used in numerous types of industrial applications, including: Elevator Cylinder Telescope cylinders Scaling ladders Earthwork machines Agriculture machines And more Wuxi YUTONG  as a professional chrome plated tubing factory, there are various types of hydraulic chrome tube,  chrome plated rod , hollow chrome rods/bars/shafts we have in stocks are standard chrome plating and  induction hardened chrome plating  . Other types of steel rods such as nickel-chrome plated rod and hollow chrome plated bars are also available on request.
