Next-Generation Semi-Flexible Grinding Discs

April 4, 2018
PFERD's grinding discs can smooth butt welds without dents or bumps to leave a completely flat surface.

CC-GRIND-FLEX, the next generation of semi-flexible grinding discs, blends weld seams on large surfaces without leaving dents or bumps typical of a rough grinding wheel or fiber disc. When using the CC-GRIND-FLEX, an absolutely flat surface can be achieved.


This complete smoothing of butt welds – without dents or bumps – is made possible by an innovative design that integrates a layered fiberglass backer with a high-performance coated abrasive. The geometry of the cooling slits ensures high air flow. This reduces the thermal load on the grinding discs and workpiece.


The CC-GRIND-FLEX, a semi-flexible version of the CC-GRIND-SOLID is available in 4-1/2 in. and 5 in. dia. with 7/8 in. bore. Coarse grit with its highly aggressive abrasive for increased stock removal or a fine grit to produce a superior finish are available. The new disc provides up to 50% less noise and vibration during use when compared to a conventional grinding disc, with less risk of gouging and is designed for weld blending on both flat and curved surfaces.


For use on steel, the new CC-GRIND-FLEX is ideally suited for automotive and trailer manufacturing to blend butt welds in fenders; as well as in power generation for water chute production. Other applications include; general metal fabrication (machine guards, security gates, etc.); maintenance and repair operations; as well as other butt-weld grinding applications.
