Aluminum extrusions are drawn through dies to
producealuminum parts with
fixed cross-sectional profiles. With hot extrusion, a cylindrical billet of
aluminum alloy is heated, forced through a die, and then cooled for subsequent
straightening, work hardening, and sawing. Cold extrusions are produced at or
near room temperature for closer tolerances and higher strength due to cold
working. Both extrusion methods produce aluminum parts with complex
cross-sections, but that require surface improvement.
Radiusing
and Deburring Aluminum
Aluminum
extruders who supply the automotive, electronics, and appliance industries
require aluminum shapes that are burr-free and slightly radiused. From air
conditioner condenser tubes to fans and heat sinks for electronics
applications, aluminum extrusions must be free of loose, torn, or folded metal
that could cause flaking and interfere with heat dissipation. Extruded aluminum
parts such as metal tracks, rails, frames, and mullions also require deburring
to remove raised edges (burrs) or unwanted material.
Flexible
Honing for Extruded Aluminum Parts
Flexible
honing tools and industrial abrasive brushes are used by aluminum manufacturers
who serve these and other industries. With its soft-cutting action and low-temperature
abrading process, a flexible hone exposes the base metal structure of
aluminum to produce a smooth, long-wearing surface. For surface conditioning,
abrasive nylon brushes are ideal for surface finish improvement after hot or
cold aluminum extrusion.
Industrial
Brushes for Surface Finishing
Aluminum
extruders and fabricators use industrial brush tools for surface finishing
and the blending of tool marks after machining or grinding. Composed of
flexible abrasive nylon filaments manufacture to a fiber-reinforced
thermoplastic base, these high-performance brushing tools can be integrated
with automated machinery, CNC machining centers, transfer lines, and robotic cells.
Applications for nylon abrasive brushes include the deburring and resurfacing
of aluminum auto parts.
