These customized CNC aluminum machined parts are precision turn-mill components used for heat dissipation, mounting and connection across electronics, industrial and automotive equipment. Each part combines a turned flange or cylinder with milled cooling fins, concentric bores and precisely located threaded holes, all machined from solid 6061- or 6063-series aluminum.
By combining CNC turning with live-tool milling in a single setup, we machine the fin array, register bores, faces and threads without refixturing, which protects concentricity, flatness and hole position even on parts with deep, thin fins. The result is a rigid, thermally efficient component that seats flat and assembles without shimming or rework.
Every part is machined to +/-0.01 mm on critical dimensions and can be sandblasted and natural or color anodized for corrosion resistance and a clean appearance. With FAI, CMM inspection and mill-certified material, we supply custom heat sinks, flanges, housings and rotary parts from prototype through high-volume OEM production.
Combined turning and live-tool milling produce complex finned and flanged geometries in one setup, with no re-fixturing error between operations.
Optimized feeds, speeds and tool paths hold deep fin arrays and thin walls without chatter or deformation, maximizing heat-dissipation area.
Natural and color anodizing, sandblasting and laser marking under one roof, with colorimeter-controlled consistency and full lot traceability.
From aerospace-grade aluminum to medical-certified engineering plastics, our in-house CNC machining centers work a broad range of metals and plastics under one roof.
