Specialty Frits for Vitreous Grinding Wheels
Our specialty glass frits are used in the vitrified bonds necessary to hold abrasives together in vitreous grinding wheels that utilize corundum, SG corundum, silicon carbide, cubic boron nitride (cBN) and diamond.
Ferro’s specialty glass frits are used to created vitrified bonds that help embed and bind abrasive grains together in traditional grinding wheels. Our glass frits enable a proper bond designed to impart hardness, strength and optimal ability for efficient cutting.
Grinding wheels made with vitrified bonds are very rigid, strong and porous. They remove stock material at high rates and grind to precise requirements.
Vitrified bonds using glass-ceramic frits will enable new sharp abrasive grains to be exposed as they wear and are expelled during the grinding process. Ferro frits can be used in grinding wheels for wet or dry precision grinding applications on the hardest materials.
Our glass frits can be used alone or in combination with clay, kaolin, quartz, feldspar, nepheline syenite or wollastonite.FERRO SPECIALTY FRITS FOR VITRIFIED BONDS IN CONVENTIONAL GRINDING WHEELS PROPERTY DATA
SG corundum and Silicon Carbide (SiC).
Depending on the melting characteristics, frits can be suitable for normal firing conditions or for lower temperature
firing cycles.
