Application of the tapered cup wheels:

• EK - white corundum and white corundum: for tool grinding of HSS tools as well as tool steels or high-speed steels.
• SiC - silicon carbide: used for hard metals, non-ferrous metals and cast materials.

Tapered cup wheels Ø = 80 x 30 x 20 mm with ceramic bond can be stored indefinitely.

The ceramic bond consists of a mixture of clay, kaolin, feldspar, quartz or glass frit. At a firing temperature between 1100 and 1250 °C, these binders sinter or melt and form the bond bridges between the abrasive grains as the pore space increases. The fired ceramic binders are largely insensitive to chemical influences. This means that they can be stored indefinitely! Due to their limited elasticity, however, they are sensitive to impact, shock and rapid temperature changes.
