Custom 5-Axis CNC Machined Aluminum Spiral Scroll Plate

This spiral scroll plate is fully machined from solid 6061 aluminum billet on a 5-axis CNC center. The multi-turn spiral arc fins, central through bore, and four locating holes are produced in a single fixture setup. It is designed as a structural volute disc for scroll-type compressors, centrifugal equipment, and precision rotary mechanisms.

This custom spiral scroll plate is manufactured by 5-axis CNC machining from solid aluminum material. The continuously extending spiral fins maintain uniform wall thickness and consistent pitch, which is critical for smooth air or fluid guiding performance. The central bore and the four distributed holes are machined with tight positional tolerance for accurate assembly.

At Chenrong Precision, our programming team optimizes the tool path to prevent thin-wall deformation during material removal. After milling, the part is deburred and ultrasonically cleaned. Critical dimensions including spiral profile, bore concentricity, and hole position are fully inspected before shipment. Lightweight aluminum construction reduces rotating mass while keeping structural rigidity, and optional anodizing enhances wear and corrosion resistance.

• Multi-turn spiral fin structure with uniform pitch and wall thickness
• One-setup 5-axis machining ensures high concentricity of center bore and fins
• Central through bore plus four locating holes for precise assembly positioning
• Lightweight 6061 aluminum, optional stainless steel for harsh environments
• Customizable spiral turns, outer diameter, thickness, and hole layout

Chenrong Precision specializes in complex thin-wall spiral CNC components. We can precisely control spiral profile tolerance and avoid machining deformation on delicate fins. Our in-house inspection provides full CMM reports for critical features. Both prototype sampling and mass production are available for compressor, pump, and rotary equipment manufacturers.
