Multiple burnishing tool

Complete machining on lathes by combining tools with high pressure internal cooling system and a tool interface for BTA tools for an automatic tool exchange. In the first instance, cylinders made of cold drawn tubes are pre-machined by a skiving head, cylinders made of hot-rolled steel tubes are counter bored before skiving process. After an automatic tool exchange, the cylinders are finish machined by roller burnishing. The tools are equipped with an internal high pressure cooling lubricant supply in order to ensure intensive cooling and lubrication as well as efficient chip removal and cleaning of the surface. Reduces side times and simplifies material flow. Machining after all welding work is completed improves quality and geometry. Investment costs for a deep hole drilling machine can be eliminated. Enables economic manufacturing of small batches. For cylinders with through and stepped bores.
