CNC Lathe Turned Aluminum Shafts, Spacers and Bushings
These are CNC lathe turned aluminum parts such as shafts, spacers, bushings, standoffs and pins. They are machined from 6061-T6 or 7075-T6 aluminum, with critical diameters held to about ±0.01 mm, then anodized, polished, plated or painted. Orders start at one piece and samples are typically available within 7 days. They suit equipment makers needing light, accurate round parts.

Manufacturing
How we make this part
Process, material options and inspection for cnc lathe turned aluminum shafts, spacers and bushings.
Turned aluminum parts are produced from round bar on CNC lathes, with diameters, shoulders, grooves and threads cut in one chucking for concentricity. Long shafts are supported by tailstocks or steady rests to prevent deflection. Spacers and bushings are often made with bar feeders for efficient batches. Edges are chamfered and burrs removed before finishing.
6061-T6 is the standard choice for spacers and bushings, offering good machinability and anodize quality. 7075-T6 is used for shafts and pins that need higher strength. Anodizing adds color and protection, while hard anodizing improves wear resistance on bushings. Polishing gives a bright finish, plating adds a metallic layer, and painting is used for color coding.
Diameters are checked with micrometers and bore gauges, lengths with height gauges, and concentricity on a CMM or with dial indicators. Critical dimensions are inspected on every part before shipment. Typical uses include spacers for electronics and machinery, aluminum shafts for light-duty mechanisms, bushings for pivots, standoffs and alignment pins.
FAQ
Frequently asked questions
Can aluminum be used for shafts?
Yes, for light-duty applications where weight matters more than strength. 7075-T6 aluminum is strong enough for many small mechanisms. For high loads, bearings running directly on the shaft, or high wear, steel or stainless steel is usually better. Hard anodizing can improve wear resistance.
What is the tightest tolerance for turned aluminum diameters?
We typically hold critical diameters to about ±0.01 mm, and down to ±0.005 mm on selected features depending on size and length. Tighter tolerances increase cost and inspection time, so we recommend applying them only to functional fits.
