The newly developed diamond burnishing tools are especially focused on the conventional burnishing of surfaces such as valves, piston rods or fittings for hydraulic or pneumatic applications. They are suitable for small geometries and materials with a degree of hardness of around 45 to 65 HRC and therefore significantly exceed the operational range of the roller burnishing tools in the range so far. According to the company, depending on the material hardness, pressure and surface property, a surface roughness of 0.03 to 0.4 Ra can be obtained. A result of 0.05 Ra is reportedly guaranteed regardless of the factors mentioned. High-tensile materials up to 1,200 N/mm can also be burnished. Burnishing an end face is performed by turning the tool. Various versions offer a variety of possible uses. The GW520 series has basic shank sizes of 10 mm and 16 mm, adaptable to other established shank sizes. By means of a scale, the tool head can be variably adjusted up to 45° and is suitable for burnishing end faces or conical flats. There are separate versions for short turning lathes and Swiss-type automatic lathes. The GW510 series, also for the basic shank sizes 10 mm and 16 mm, is provided as a cost-effective alternative for standard applications.

Technical details are still being worked out, the test phase is running. The special properties and the functionality of the new Zeus diamond burnishing tool will be introduced to industry professionals at EMO Hannover 2017.
