Product Description
Custom 5-Axis CNC Machined Large Arc Aluminum Rotor Bracket
Quick detail
This large arc aluminum rotating frame is custom-manufactured on 5-axis CNC mills. It features integrated multi-hole positioning bosses and pocket cutouts, machined from solid aluminum billet. The sandblasted matte finish delivers stable mechanical performance, designed for robotic rotary joints and automated motion systems.
Product description
Chenrong Precision manufactures this large curved rotating frame in our domestic CNC workshop. The part has a wide semicircular arc contour, multiple precision mounting holes and recessed pockets, which requires 5-axis simultaneous machining to achieve smooth curved transitions and coaxial tolerance.
We adopt solid block milling instead of casting to eliminate internal porosity, critical for dynamic rotary load. Every hole position and boss feature is inspected by CMM to ensure assembly accuracy. Our factory handles sandblasting surface treatment internally to shorten lead time. We support custom revision based on client CAD files, from prototype validation through low-volume trial to full mass production, serving robot integrators and automation machinery manufacturers.

FAQ
Q: Can you adjust the arch radius of this robot frame?
A: Yes, send your 3D CAD drawing or specify radius dimension, our engineers will review machining feasibility.
Q: Which aluminum grade is better for high-speed robot movement?
A: 7075 aluminum is recommended for high dynamic load; 6061 is cost-effective for general robot applications.
Q: Can hard anodizing be applied after sandblasting?
A: Yes, sandblasting plus hard anodizing is available to enhance surface hardness and corrosion resistance.
Q: What is the sample lead time?
A: 8-10 working days for prototype samples. Mass production lead time depends on quantity and surface treatment.
Q: Can you provide CMM inspection report?
A: CMM dimension report can be provided upon request for critical structural robot components.

SKlarer Kaufgrund: Preis-Leistung stimmt. Kleiner Hinweis: Die englische Produktbeschreibung ist knapp, aber die technische Zeichnung auf Anfrage war vollständig. Gerne wieder.

EProbably an unusual use case: I needed a modern, clean-looking bearing housing for a rotating art piece going into a lobby installation. Most off-the-shelf bearing blocks are cast iron or painted steel and look clunky. This aluminum post with the triangular flange and brushed finish fits the aesthetic I wanted. Machining quality held up, no visible tool marks, edges clean. The artist client didn't even realize it was a "made for machines" part.
