WIW Internal Roller Burnishing Tools for cylindrical drill holes produce a fit with only one operation. During the process either the workpiece or the tool may rotate. To satisfy our customer expectations for the precision, the tools can be adjusted freely on a micron scale. WIW tools can be ordered for through hole or blind hole applications. Through hole tools may be used either with self-feeding or machine feeding, blind hole tools are only suitable for machine feeding. The surfaces can be burnished to roughness values below Rz 1μm with high bearing ratio up to tp = 95 % by one pass (see chapter 4). The tool can process all workpieces with the same adjustment interior H7 tolerance after adjusting it to the size you wish to make process with. The manufacturing costs you save are: · Low burnishing cost · Pre-machining and burnishing occur on the same machine, by this means the necessity of second machine and labour of fixing workpiece are removed. · One setting, One pass, · Very short process time, · No saw dust or residue, · Low energy consumption. A few examples for products that require smooth surfaces: • oil pumps and valves • piston rods • connecting rods • bearing seat • shafts • hydraulic cylinders • ball joints • conical seats • pistons • gear parts • clutch parts
