Whereas grinding materials in their early times were only used for “rough“ processes such as deburring and rounding, they are nowadays high-precision tools that are even used for the super finishing of the most fragile and highly sensitive components. In these procedures, roughness values of up to 0.2µm are reached. The precise adaptation of the high-precision grinding material to the individual requirement allows for this high quality level. Being the world’s leading manufacturer of processing media for vibratory finishing, Rösler offers more than 8,000 types of consumables, about 4,500 of which are grinding materials that differ in shape, size and composition. Our spectacle frame industry can make do with approx. 250, with new shapes and ingredients being developed on an on-going basis and tailored to customers´ exact needs.
