Metal Spinning Produces Tight Tolerance Components

Posted by Samuel Ibrahim, Jr. on Mon, Mar 02, 2015

Depending on the specific form and structure of a component, there can be more than one metal fabricating process that can be used to meet the same end. Although different processes can achieve similar results, there may be greater benefits of one over another.

Metal spinning, a process that forms axially symmetrical parts, is a fairly simple process that produces advanced results. Metal spinning is not traditionally thought of as an advanced process, but technological innovations have enabled the production of components that require extremely tight tolerances.

Combining the past with the present, metal spinning joins together the skills of the craftsmen with the automation of current machine technologies. Since this process forms a metal component on a lathe instead of stamping, cutting, or deep drawing, metal spinning calls upon the expertise of the machinist and the equipment to meet the required specifications.

There are two types of metal spinning options available: CNC and hand spinning. Both processes form a metal disk over a block to produce conical, cylindrical, parabolic, toroidal, venturi, and hemispherical shaped pieces. Also, these processes offer unique benefits, and the combination of the two can create finished products of even higher quality.

CNC spinning machinery enables high production capabilities and allows high strength materials to be formed accurately. It is a highly repeatable process that delivers precision results; automated and CNC spinning that is assisted with hydraulics replaces expensive tooling required for stamping and produces more cost-effective components.

Hand spinning is suitable for smaller runs and all types of industrial and precious metals and alloys. Perfectly finished parts, without stretch marks or wrinkles, are consistently achieved. Hand spinning is ideal for prototyping, products of varying sizes, and architectural and decorative pieces.

The inherent level of repeatability found in metal spinning enables the production of tight tolerance componentry. Due to this fact, metal spinning is just as effective as other fabricating processes.
