CNC Machining of Aluminum Expansion Coupler for the Electrical Hardware Industry

Custom Aluminum Expansion Coupler Fairchild Auto-Mated Parts, Inc. CNC machines 2,500 to 5,000 expansion couplers annually for a client from the electrical hardware industry. Used within a rain-proof conduit connector, these couplers are made from 6061 aluminum, and measure 6.505" in length and 1.54" in outside diameter, with a 1.528" x 1.025" material extrusion.

Holding tolerances as close as ± .001", we use a combination of our 3-axis CNC lathe and CNC-retrofitted screw machine to manufacture each coupler. Customer part numbers and brand logos are also roll-engraved onto the exterior surface of the couplers, and we perform in-process testing and final inspections to ensure all units meet client expectations for quality. Once completed, the expansion couplers are shipped to various North American locations.
