Abstract

Przedmiotem zgłoszenia jest spoiwo szklanokrystaliczne do narzędzi ściernych według zgłoszenia, które charakteryzuje się tym, że zawiera następujące składniki, których ilości określone są w procentach wagowych (%wag.): SiO<sub>2 </sub>- 25-65%; Al<sub>2</sub>O<sub>3</sub> - 0,5-20%; B<sub>2</sub>O<sub>3</sub> - 0,5-30; K<sub>2</sub>O – 0,5-10%; LiO<sub>2</sub> – 0,5-15%; CaO – 0,5-15%; MgO – 0,5-10%; ZnO - 5-30%; Na<sub>2</sub>O – 0,5—15%. Spoiwo według zgłoszenia pozwala na obróbkę cieplną ściernic z ziarnem elektrokorundowymi i mikrokrystalicznym w temperaturze do 940°C. Zgłoszenie rozwiązuje zagadnienie składu spoiwa ceramicznego, w którym ziarna ścierne z tlenku glinu mono - lub mikrokrystaliczne połączone są spoiwem szklanokrystalicznym o wyższej odporności na kruche pękanie w porównaniu do znanych spoiw szklanych dzięki obecności wygenerowanych faz krystalicznych w spoiwie, co wpływa bardzo korzystnie na proces obróbki wykańczającej.The subject of the application is a glass-crystalline binder for abrasive tools according to the application, which is characterized in that it contains the following components, the amounts of which are specified in weight percentages (wt%): SiO<sub>2</sub>- 25-65%; Al<sub>2</sub>O<sub>3</sub> - 0.5-20%; B<sub>2</sub>O<sub>3</sub> - 0.5-30; K<sub>2</sub>O – 0.5-10%; LiO<sub>2</sub> – 0.5-15%; CaO – 0.5-15%; MgO – 0.5-10%; ZnO - 5-30%; Na<sub>2</sub>O – 0.5—15%. The binder according to the application allows for heat treatment of grinding wheels with electrocorundum and microcrystalline grains at temperatures up to 940°C. The application solves the problem of the composition of a ceramic binder in which mono- or microcrystalline alumina abrasive grains are connected with a glass-crystalline binder with higher resistance to brittle fracture in comparison to known glass binders due to the presence of generated crystalline phases in the binder, which has a very beneficial effect on the finishing process.
