Custom CNC Machined Aluminum Curved Arc Support Mounting Bracket

Custom CNC Machined Aluminum Curved Arc Support Mounting Bracket

Quick detail

This custom aluminum curved support bracket is manufactured on multi-axis CNC milling machines. The large semicircular arc surface, stepped mounting base and precision hole array are fully machined from solid aluminum block. Designed as load-bearing mounting support for industrial automation and motion systems.

Product description

This arc-shaped support bracket is milled from solid 6061 aluminum billet. The critical semi-circular curved surface maintains consistent roundness tolerance, paired with distributed mounting holes for stable assembly. The reinforced rib structure improves overall rigidity while keeping the component lightweight, effectively resisting vibration during high-speed equipment operation.

At Chenrong Precision, we evaluate stress requirements at the drawing review phase, optimize material removal paths to minimize machining deformation. Each bracket undergoes deburring and precision dimension inspection after milling. Our factory is equipped with advanced machining and measuring equipment to handle prototype and batch orders for automation structural parts. Surface treatments such as clear or black anodizing can be added to boost corrosion resistance for long service life.

FAQ

Q: Can you adjust the arc radius of this aluminum support bracket?

A: Yes, all geometric dimensions including arc radius, hole spacing and overall outline can be customized according to your drawings.

Q: What are the lead times for prototype and mass order?

A: Prototype lead time normally 7–10 working days. Mass production lead time will be quoted based on quantity and surface treatment requirements.

Q: Is hard anodizing recommended for this load-bearing bracket?

A: Hard anodizing improves surface hardness and wear resistance. We will suggest suitable surface finish according to your working environment.

Q: Can you guarantee the roundness of the curved surface?

A: We use roundness tester and CMM to inspect arc profile, and provide inspection reports for critical features.

Q: What if I need to change hole positions after prototype testing?

A: We support drawing revision and re-make samples, we will re-evaluate the manufacturing cost for revised design.
