Majstrenko, Anatoly F. Lisovsky, Registration Date 29-12-2004 Organization V.Bakul Institute for Superhard Materials popup.description2 The mathematical model has been developed of rock-destructing elements of a bore bit interaction with a rock massive which takes account of shape and temperature-dependent thermal properties of bore bit elements and cooling regime. Based on the obtained theoretical and experimental results, the thermomechanical concept is formulated of drilling tools designed for work in the limited heat exchange conditions. The principally new construction of a special diamond bore bit has been designed, which ensures boring of rock and concrete without direct cooling of a cutting zone. The new technique of sintering the mesostructured tungsten carbide alloys has been designed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
