Изобретение относитс к области нроизводства абразивного инструмента.This invention relates to the field of manufacturing abrasive tools.
Известны керамические св зки, используемые дл изготовлени абразивного инструмента на основе электрокорунда. Однако известные св зки не наход т применени дл изготовлени инструмента на основе карбида кремни , так как последний разлагаетс в процессе плавлени св зки, не обеспечива удовлетворительной прочности инструмента.Ceramic ligaments are known for use in the manufacture of an electrocorundum abrasive tool. However, the known bindings are not used for the manufacture of silicon carbide based tools, since the latter decomposes during the melting process of the binder without providing satisfactory tool strength.
С целью устранени указанного недостатка предлагаетс в состав фритты вводить окислы Ni203 или Сг20з. При этом повышаетс реакционна способность св зки, уменьшаетс потребное количество ее и увеличиваетс механическа прочность ипструмента.In order to eliminate this drawback, it is proposed to introduce the oxides Ni203 or Cg20z into the frit. This increases the reactivity of the binder, reduces the amount required and increases the mechanical strength of the tool.
