PFERD has introduced the POLIVLIES ceramic oxide CO-COOL flap disc, the newest addition to its popular line of POLIVLIES nonwoven products. Premium CO-COOL abrasive material provides consistently high grinding performance, with special top-sizing for reduced loading and cooler grinding on poor heat-conducting materials. The innovative interleaved flap construction alternates between aggressive coated abrasive and nonwoven material, allowing for grinding followed by surface conditioning in a single operation.
These discs are recommended for work on large surfaces made from stainless steel (INOX) but can be used on nearly all materials and deliver increased economic efficiency due to high abrasive performance and long service life. Featuring high flexibility, they create a consistently high surface quality. They are compatible with angle grinders, including cordless angle grinders.
POLIVLIES CO-COOL discs are available in 4-1/2 and 5 in. diameters, in both plain arbor hole and threaded hub configurations with a maximum speed of 13,300 rpm. They are available in coarse-100, medium-180 and fine-240 grit sizes. It is recommended that the discs be used at a peripheral speed of 6,000 to 6,900 sfm.
PFERD also provides POLIVLIES flap discs with aluminum oxide A abrasive. These discs excel at universal grinding primarily in industry and the professional trades. They also come in coarse, medium and fine grades with a recommended peripheral speed of 6,000 to 6,900 sfm.
Related Glossary Terms
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.
- aluminum oxide
Aluminum oxide, also known as corundum, is used in grinding wheels. The chemical formula is Al2O3. Aluminum oxide is the base for ceramics, which are used in cutting tools for high-speed machining with light chip removal. Aluminum oxide is widely used as coating material applied to carbide substrates by chemical vapor deposition. Coated carbide inserts with Al2O3 layers withstand high cutting speeds, as well as abrasive and crater wear.
Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.
- coated abrasive
Flexible-backed abrasive. Grit is attached to paper, fiber, cloth or film. Types include sheets, belts, flap wheels and discs.
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.
