Swaging Machines

Felss precision automatic swaging machines can be used in the optical industry for such applications as the shaping of spectacle frame temples, as well as for economic production of small tapered and recessed parts.

Automatic multi-station machines, designed in a modular concept, available in multi-station configurations enable the complete manufacturing of spectacle frame temples in one single pass.

Operations:

  • straightening
  • cutting to length
  • feed-swaging
  • recess swaging
  • pointing
  • cutting-off

Depending on design and degree of automation of the machine, temples are made from wire blanks or direct from a wire coil. Furthermore, spectacle frame temples stamped from sheet metal can be swaged round and pointed. Corresponding workpiece magazines resp. vibratory feeders are available for automatic machine loading.

Some special machine models swage pieces direct from the coil, cut them exactly to length and transfer them to subsequent machine stations.

Productivity and Flexibility thanks to NC-Technique

For small batches of a particular shape, the productivity of a machine is strongly influenced by the tooling change times. The newly designed FELSS NC-technique, which is available optionally for all transfer lines, helps our customers reduce down times.

The adjusting parameters for a large number of different temple styles can be memorized and called up any time. At "the touch of a button" the memorized data can be recalled for the chosen workpiece. The operation with interpolating NC-axes is possible. Correspondingly the new FELSS-NC-technique can also be applied to single-headed machines, which are working directly from a wire coil and which are primarily used for samples and low volume production. The handling of the FELSS-NC- technique can be learned easily, as all the control commands are by screen-dialog and thus user-friendly.

Easy handling and quick change over

When contemplating production of medium and large temple series, it will always be necessary to perfectly adapt the swaging dies to the individual workpiece shape (no operation with interpolating NC-axes). Therefore, when changing to a different temple style, it is crucial to exchange the swaging dies and probably other tooling components which correspond to the diameter of the workpieces. Thanks to various technical improvements it has been possible to further simplify the unavoidable manual changing operations, i.e. the exchange of the clamping dies.

A Class instead of mass

The proven type of FELSS Precision Rotary Swaging heads HE 16 and the newly designed series HE 10 are perfectly adapted to the requirements of the optical industry. Extensive tests in our workshops have shown that the swaging head HE 10, notwithstanding

of its compact design, incorporates a high level of stability and ensures perfect repetitive accuracy.
