PFERD has introduced its CC-GRIND-FLEX, the next generation of semiflexible grinding discs. This high-performance disc 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 semiflexible 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 percent less noise and vibration during use when compared to a conventional grinding disc, with less risk of gouging and is for weld blending on both flat and curved surfaces.
For use on steel, the new CC-GRIND-FLEX is 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.

- abrasive
abrasive
Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.
- coated abrasive
coated abrasive
Flexible-backed abrasive. Grit is attached to paper, fiber, cloth or film. Types include sheets, belts, flap wheels and discs.
- flat ( screw flat)
flat ( screw flat)
Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding wheel
grinding wheel
Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.
