PFERD miniature brushes for cleaning and light deburring give users a competitive advantage by providing highly repeatable deburring and surface-conditioning results on a variety of materials, from hard alloys to soft aluminum. The lineup of wheel, cup and end configurations includes stem-mounted miniature brushes that are ideally suited for the precision applications required in many industries, including electronics, medical, aerospace and jewelry.
The brushes are available with a wide selection of filaments, including: carbon steel wire, stainless steel (INOX), brass wire, aluminum oxide abrasive filament and a variety of soft or stiff natural bristles. All the stem-mounted miniature brushes are mounted on 1/8-in. stems, and are recommended for use with variable speed die grinders. Wheel brushes come in diameters up to 1-1/2 in., cup in 9/16 in. diameter and end configuration to 5/16 in. diameter.
The innovative M-BRAD, available as an aluminum oxide filament is a 6.12 nylon microfilament that evenly encapsulates various abrasive grit particles on the surface as well as throughout the nylon filament. The flexibility of strands makes it uniquely effective when deburring complex parts. It yields consistent gradual cutting action, permitting precise control in applications ranging from cosmetic surface preparation on brass or soft aluminum, to edge blending on materials as tough as titanium and carbide. They are also effective on materials such as wood or glass. In addition, M-BRAD brushes yield longer tool life than nonwoven synthetic abrasive products, and are suitable for both wet and dry surface conditioning, although the use of coolant is recommended.
The effective cleaning action of these brushes removes sharp cross-hole burrs, metal sliver residues and sharp corners that result from the drilling of close-tolerance hard metallic and nonmetallic parts.
Related Glossary Terms
- 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.
- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- aluminum oxide
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.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
