Spinning is a plastic forming process that utilizes a spinning machine to drive a metal blank into high-speed rotation. Simultaneously, a spinning wheel applies pressure to the rotating blank, gradually conforming it to the mold shape to produce hollow rotary parts. The machinery involved includes spinning machines, spinning dies, spinning tools, tailstock devices, feeding mechanisms, lubrication systems, and control systems. It can process materials such as aluminum sheets, copper sheets, stainless steel, carbon steel, titanium alloys, and other deformable metallic materials.
To meet the processing demands for irregular rotary components such as circular, conical, and parabolic surfaces (e.g., decorative closures, pipe fittings, and lamp housings), Ruichi has introduced CNC spinning technology to achieve efficient, precise, and integrated forming. The company utilizes multi-axis CNC spinning machines driven by servo motors, with spindle speeds reaching 3000 rpm. These machines can process metal rotary components up to 1200mm in diameter and 8mm in thickness, maintaining forming accuracy within ±0.1mm. During spinning, CAD/CAM systems precisely program the feed trajectory, speed, and pressure of the spinning wheel. This ensures uniform deformation of the metal blank as it rotates, conforming to the mold’s shape. Compared to traditional casting and welding processes, CNC spin-formed components offer advantages such as uniform wall thickness, high structural strength, and low surface roughness (Ra ≤ 6.3μm). Material utilization exceeds 98%, significantly reducing production costs. This process accommodates both single-piece and small-batch custom production while meeting large-scale manufacturing demands, adapting to diverse architectural customization requirements. To ensure spinning quality, Ruichi has established a comprehensive spinning die maintenance system. Dies undergo regular precision calibration and polishing to guarantee consistency and aesthetic appeal in formed products. This enables the supply of high-quality irregular rotary metal components for automotive wheel covers, home appliance housings, new energy equipment, mechanical parts, electronics, and electrical appliances.
From raw material intake through stamping, bending, laser cutting, stretching, spinning, and subsequent assembly and inspection, real-time data recording and analysis across every process enables management to monitor production progress and quality status promptly. Additionally, clear quality control standards are established for tasks including workshop material handling, stamping feeding, and product sorting. This effectively minimizes quality fluctuations caused by human factors, ensuring stability and controllability throughout the entire production process.
