Title: The Innovative Mind of Stig E Lagerberg
Introduction
Stig E Lagerberg, a prominent inventor based in Sandviken, Sweden, has made significant contributions to the field of machining technologies. With a total of 12 patents to his name, Lagerberg's work focuses primarily on cutting tools and processes that enhance efficiency and performance in chip cutting machining.
Latest Patents
Among his latest innovations are two noteworthy patents. The first is for a machine designed for chip cutting machining, alongside a cutting tool specifically for such machines. This cutting tool features a front part that incorporates a cutting insert and a rear part that can be detachably mounted in a holder within the applicable machine. It boasts multiple nozzles that spray high-pressure cooling liquid towards the cutting insert. The design includes a duct system within the tool that ensures a consistent supply of cooling liquid to the nozzles, which are adjusted to direct jets toward distinct points of impact on the cutting insert. Individual ducts can be closed, allowing for precise control over the cooling process.
The second patent involves chip removing machining of a workpiece, utilizing a cutting tool with a cutting insert. In this inventive setup, one or more over-cooling nozzles direct jets of cooling liquid towards the contact area between the workpiece and the cutting insert's chip surface, while a sub-cooling nozzle targets the flank surface. The focused application of cooling liquid can be manipulated to emit from either nozzle separately or simultaneously, improving the machining process.
