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.
• Produces super finish surface, with a bore tolerance of IT8, thereby reduces the sealing wear making it ideal for pistons.
• The tool can be optimized for both skiving and roller burnishing operations.
