Development of the Technology for Manufacturing and Introducing a New Class of Tools with CVD Diamond for Grinding High-Precision Gear Wheels of Special Gear Units

wheels Materials and Methods. Techniques and special stands for precise positioning of elements from CVD diamond and for testing the trueing instrument, methods for determination of metallic binder’s structure. Results. The rational positioning of CVD diamond elements on the cases of complex shapes has been studied. The manufactured tools for trueing abrasive wheel have been finished and tested. It has been shown that the use of such elements provides a high resistance to the erosion influence of sludge in the trueing area and is expedient to be used in contact with the main components of abrasive wheels, due to exceptional tribological characteristics. The use of structured metallic binders has been shown to provide low vibrations in the trueing area and a stable and reproducible topography of the cutting surface of an abrasive tool with a large number of cutting edges and with the capability of directional influence on the orientation of the edges by selecting efficient trueing conditions. Conclusions. For the first time in Ukraine, at the Bakul Institute for Superhard Materials of the NAS of Ukraine, the truing tools equipped with CVD diamond elements have been created and adapted to the processing chains of high­precision gear wheels of reducer units with enhanced operational characteristics, which enable replacing the imported parts at the machine­building enterprises of Ukraine.
