CNC Aluminum Spacers & Bushings

Custom CNC aluminum spacers and bushings are defined by their bore, outside diameter, overall length and mating interfaces. HKAA reviews customer drawings to plan the turning and any secondary machining required for the specified geometry.

Dimensions, Fits and Threads

Specify the bore and outside diameter tolerances, length, shoulders, chamfers and any grooves. Identify the surfaces and datums that control alignment in the assembly. If a component includes a threaded bore or mounting feature, state the thread designation, pitch, depth and inspection requirements. Intended function and material suitability remain subject to your design requirements.

Alloy, Finish and Inspection

Define the aluminum alloy and temper, together with surface finish and masking requirements. Identify dimensions that must be checked after finishing, and any first-article or inspection documentation required. See our 6061 aluminum machining guide for related material considerations.
