Metal Spinning Guide: Flow Forming & CNC Spinning of Revolved Parts

Short answer: Metal spinning forms axisymmetric parts by pressing a spinning disc or tube of sheet against a rotating mandrel — a low-tooling, highly ductile process ideal for cones, domes, vessels and reflectors in low to medium runs.

How Spinning Works

A blank spins on a lathe while a roller presses it onto a mandrel, flowing metal into the shape without a closing die. It is gentler than Metal Stamping Supplier and pairs with Metal Bending Guide; forming limits follow Metal Formability Guide и Aluminum Temper Designations.

Spinning vs Other Forming

Tooling is far cheaper than stamping dies, so spinning suits prototypes and medium runs of revolved parts (compare Casting Supplier и Forging Supplier). Flow forming thins and elongates the wall for strength — context for Yield Strength Vs Tensile Strength и Metal Strain Hardening Guide.

Часто задаваемые вопросы

What is metal spinning?

Forming axisymmetric parts by pressing a spinning sheet or tube against a rotating mandrel with a roller.

When is spinning better than stamping?

For low-to-medium runs and prototypes where die tooling cost would be hard to justify.

What shapes can be spun?

Cones, domes, cylinders, vessels and reflectors — anything with rotational symmetry.

Which metals spin well?

Ductile metals: aluminium, stainless, copper and mild steel in suitable tempers.

Does spinning change wall thickness?

Flow forming can thin and elongate the wall, increasing strength along the part.
