Principles of Metal Spinning
旋压原理
标签：旋压, 原理, 概述
旋压（Metal Spinning / Spinning）是把圆形金属板（坯料）在机床上随主轴高速旋转，用滚轮（旋压棒）逐步压向模板，使其塑性变形成回转体（碗、灯罩、壶身）的工艺。属"局部渐进成形"，模具简单（只需一个同心模板），适合中小批量与大型薄壁件。铜板旋压因延展性好而极为常见。
Metal spinning forms a rotating circular blank against a chuck (form) using a roller, progressively shaping it into an axisymmetric part (bowls, shades, vessels). It is "incremental local forming" — the tooling is just one mandrel, ideal for low/mid volumes and large thin-walled parts. Copper is a favorite for its ductility. ---
