Engineers of our company designed support shoe for superfinishing machines using advanced superhard material named zirconium oxide. This material applies in a a wide range of industries from dentistry to gas analyzers. Its application will allow to increase the durability of shoe supports in several times, as well as the accuracy of the grinding operations, which will improve the quality of microgeometrical parameters of bearing rings. Company Duma & Vizbules Tehnika (a leading manufacturer of zirconium oxide products in Riga) took over the production of the shoe supports by Baltic Bearing Company request. Prototypes were made on 5-axis milling machine. Manufacturing error is not more than 15 microns.
