Custom CNC Milling Aluminum Alloy Angle Bracket

This custom CNC machined aluminum angle bracket is manufactured by 5-axis CNC milling process. It adopts an integrated angular structure with multiple through holes, counterbore holes, slotted holes and special avoidance grooves distributed on different surfaces. The complex multi-directional hole and cavity features are finished in one clamping to guarantee excellent positional accuracy.
We strictly control flatness, perpendicularity, hole position tolerance and surface roughness during processing. The integrated structure eliminates assembly gaps and deformation risks, delivering stable load-bearing performance and high repeat positioning accuracy. The protective blue film on the surface is used to prevent scratches during processing and transportation, which can be peeled off before assembly.
Aluminum alloy 6061, 6063, 7075 are available for selection. Various surface treatments can be provided as requested, including clear or colored anodizing, hard anodizing, sandblasting, polishing and chromate conversion. Aluminum alloy features lightweight, good rigidity, excellent thermal conductivity and anti-oxidation performance.
This multi-hole aluminum connecting bracket is widely used in automation production lines, robot frames, test jigs, optical equipment, packaging machinery and linear motion modules. It serves as a high-precision connecting and positioning support component for mechanical assembly.
We support OEM & ODM customization based on your 2D drawings, 3D files or physical samples. Fast prototype proofing, small-batch trial production and large-volume mass production are all acceptable. Our engineering team will review your drawings, optimize machining layout and provide professional suggestions to balance precision requirements and production cost.
Feel free to send your drawings with tolerance and surface requirements for an accurate quotation.
