In the current production industry, metal spinners are essential, as they provide precision, versatility, and economical solutions across a broad spectrum of industries. Metal spinning offers unmatched precision and repeatability, whether you need single, custom prototypes, small-scale production, or large volumes of components. At Winward Engineering, our metal spinners are used in the aerospace, automotive, architectural, and general engineering industries, ensuring that all products are of the highest quality.
What is Metal Spinning?
Metal spinning is an art that involves high-speed rotation on a lathe, during which a metal disk or tube is rotated, and tools cut it into symmetrical shapes. It can be referred to as spin forming or shear spinning. The process enables manufacturers to make parts such as cones, cylinders, hemispheres, and domed ends to the correct size and with a fine surface finish.
Hand Metal Spinning
One of the oldest processes is hand metal spinning, in which sheet metal is shaped using manual tools. This method is cost-effective and ideal for one-off prototyping and low- to medium-volume production when precision is required. Industries such as lighting and aerospace frequently use hand metal spinning to produce custom designs.
Hydraulic Metal Spinning
Hydraulic metal spinning uses a hydraulically powered lathe to shape heavier or larger parts. It is ideal for small- to medium-batch production in architectural, pressure, and general engineering. This method is effective for manufacturing components such as cones, cylinders, and dished ends.
CNC (PNC) Metal Spinning
PNC metal spinning combines hand-held methodologies with CNC automation based on teach-in technology and, relative to mass production, was used to duplicate tool movements. It is an applied technique in the HVAC, lighting, and general engineering industries that minimises lead times and unit cost and provides uniform quality.
Flow Forming
Flow forming is performed by starting with a pre-prepared tube or bowl attached to a mandrel. The material is passed between several rollers that force it to stretch in the axial direction, reduce wall thickness, and increase strength. Flow forming is also ideally suited for high-precision conical or cylindrical components in the nuclear, pressure, and engineering industries.
Shear Forming
This is also known as shear spinning, an advanced process that produces tapered parts in a single step through controlled material thinning. Shear forming has various applications in food, architectural, and general engineering sectors and is used to make intricate formed shapes with high structural integrity.
Flange Forming
Flange forming uses extensions or flanges on the flank of the cylindrical shape, which are already made. This process is typically needed when female tooling is required, commonly in HVAC, lighting, and general engineering processes, with accurate and repeatable results.
