Metal spinning with maximum precision

Anything round is clearly a job for Heggli & Gubler AG. Whether the part you need is small or large, we can meet your requirements with our extensive machinery. As one of the leading companies for metal spinning services, we are the right partner for you – from prototypes and custom one-off items right through to entire series.

  • Metal spinning for circular blank diameters of up to 2000 mm
  • Material thicknesses from 0.3 to 5.0 mm, depending on material and degree of deformation
  • Materials: aluminium, non-ferrous metals, steel, stainless steel, nickel alloys, titanium
  • Additional services: welding, turning, milling, grinding, punching

‘Metal spinning also involves clamping a circular sheet metal blank in front of a mandrel, with the spinning mandrel representing the inner geometry of the component (forming tool). The mandrel is then rotated together with the circular blank. This is the task of the main spindle drive on the spinning machinery, but occasionally relies on nothing but elbow grease.’

Some metal spinning facts

Metal spinning is a specific technique for forming sheet metal that Heggli & Gubler AG has perfected. Thanks to our high level of vertical integration, we are able to respond to customer needs at lightning speed.

During metal spinning, a sheet metal blank (usually circular) is clamped in front of a rotating mandrel that corresponds to the geometry of the component’s interior. The circular blank is shaped into the component in several stages using a spinning tool. For this, Heggli & Gubler relies on hydraulically controlled metal spinning machines.

Typical industries that make use of metal spun parts and for which Heggli & Gubler acts as a supplier are:

  • Chemicals
  • Pharmaceuticals
  • Medicine
  • Plant engineering
  • Apparatus engineering
  • Aeronautics
  • Aircraft construction
  • Turbines
  • Lighting industry
  • Electrical industry
  • Process technology

Benefits of metal spinning

  • Suitable for small and medium batch production
  • Ideal for making prototypes
  • Low tooling costs
  • Cost-effective technique
  • Short delivery times

Types of metal spinning

  • Spinning by machine
  • Spinning by hand
  • Support spinning
  • Hydraulic spinning

Speciality

Another technique that Heggli & Gubler AG has mastered is flow forming. In this process, the high contact pressure of the tool forms the sheet metal in such a way that the thickness changes, e.g. from 4 to 0.5 mm. As a result, the material undergoes
major deformation. The important thing here is to ensure that the surface structure remains even.
