Custom CNC Precision Aluminum Positioning Fixture Pin
Quick Detail
High-precision custom aluminum fixture pin made via CNC turn-mill machining. Adopts stepped shaft and flat slot structure for accurate repeat positioning. Lightweight aluminum alloy with optional anodizing treatment, widely used for automation fixture locating, supporting prototype and mass custom production.
Product Description
This custom aluminum positioning fixture pin is a core locating component for industrial precision tooling. Produced by one-time clamping CNC turn-mill composite machining, the part achieves excellent dimensional consistency and coaxiality. The integrated stepped outer diameter and flat positioning slot ensure stable, repeatable positioning during equipment clamping and assembly. Aluminum alloy material reduces fixture load while maintaining structural rigidity. Optional anodizing further improves surface hardness and wear resistance, suitable for long-cycle automated production and precision testing scenarios.

FAQ
Q1: Can I customize the pin diameter, length and slot position?
A1: Yes. All dimensions, step sizes and slot positions can be fully customized according to your 2D/3D drawings with free DFM evaluation.
Q2: Which aluminum material is better for fixture pins?
A2: 6061 aluminum balances cost and performance for regular use; 7075 aluminum is recommended for high-load and high-precision fixture scenarios.
Q3: Does anodizing affect positioning accuracy?
A3: No. We control precise coating thickness to ensure the final dimension and positioning tolerance fully meet requirements.
