LEIFELD Metal Spinning and Shear Forming Economics

  

The cost-effectiveness of metal spinning and shear forming (single forward pass spinning) is characterized on the one hand by the possibility of combining the two techniques and on the other by the range of secondary forming or machining operations which can be carried out in the same setup.

Compared to methods such as pressing and deep drawing, spinning and shear forming involve lower forces and require less power. This in turn means that the equipment can be cost-effectively engineered in terms of rigidity and size as well as the number of individual assemblies.

In contrast to punches and dies, spinning tools are inexpensive, since only a mandrel with the contour of the inside of the final part is needed. In special cases spinning on air is possible.

As with all processes quality improvements are obtained by optimizing the relevant parameters. Here too, changes are quickly and easily accommodated by program editing (Online at the machine or with our Offline Software). Also tooling can be modified quickly and easily at minimum cost.

The wide variety of shapes which can be produced offers virtually unlimited opportunities for the designer as well as for new applications. Particularly where re-entrant shapes are involved, the designer has so many options which would be impossible with other competitive methods.

On-going work to optimize both equipment and processes is producing ever higher quality standards. Other distinguishing criteria include:

- high degree of flexibility

- higher level of automation

- optimum grain flow

- very low risk of crack propagation

- high mechanical strength and hardness

- cost reductions through high material yield

- different operations possible in one set-up

- favorable cycle times

Whatever the application, spinning and shear forming offer attractive cost benefits. This applies equally to the production of one-offs and prototypes as to small to medium runs and, for certain applications, large volume manufacture.
