Custom 5-Axis CNC Machined Aluminum Spiral Scroll Plate

Custom 5-Axis CNC Machined Aluminum Spiral Scroll Plate

Quick detail

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 one fixture setup. It is designed as a structural volute disc for scroll-type compressors, centrifugal equipment and precision rotary mechanisms.

Product description

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. 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.

Product Features

• 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

Product Advantage

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.

Application

• Scroll compressor structural disc
• Centrifugal pump volute flow-guide plate
• Precision rotary mechanism supporting disc
• Air/fluid guide component in automation equipment

FAQ

Q: Can you customize the number of spiral turns and pitch?

A: Yes, spiral turns, pitch, fin thickness, outer diameter and overall height can all be customized according to your CAD drawing.

Q: What material should I choose for this spiral plate?

A: 6061 aluminum for lightweight general use; 7075 for higher strength; 304/316L stainless for corrosion and high-temperature scenarios.

Q: Is the center bore and locating holes adjustable?

A: Absolutely, bore diameter, hole quantity and hole distribution can be modified based on your engineering requirements.

Q: How do you prevent thin-wall deformation during machining?

A: We use optimized tool paths and stepped material removal, plus supporting fixtures, to control deformation on thin spiral fins.

Q: What is the sample lead time?

A: Normally 8-10 working days for prototype, mass production lead time depends on quantity and surface treatment.
