THE ADVANTAGES OF SKIVING AND ROLLER BURNISHED TUBE
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 ...
