HIGH PRESSURE COOLER FOR CUTTING TOOLS AND WORK PIECES

This paper presents a part of the theoretical and experimental researches carried out on the design and realization of a high-pressure cooling installation for turning centers. Besides the general theoretical aspects, adaptable to most of the existing machine tools, the work emphasizes especially those of modern machine tools (CNC), which are processing with high cutting speeds, in the case of series and mass productions. The projected and designed installation is designed for a turning machining center based on a SC14 vertical lathe and allows the tool and the semi-product to be cooled by program control from the outside of the tool and, where appropriate, through the inside of the tool. The authors present some aspects of the necessity and the advantages of using this installation, and also the scheme and its construction.
