Fin Rolls

Fin rolls combine gearing and cutting knowledge. At JEM we are true specialists in both worlds.

Our entire team is focused on finding innovative solutions that allow to optimize the geometry of the fin produced and the performance of the rollers, reducing the production cost as much as possible.

JEM engineers work closely with our customers' technical team. We call this collaboration the Tool Optimization Program and it has allowed us to develop the High Performance (HP) rolls for all of our fin rolls.


Fin rolls customization


JEM rolls adapt to any fin forming machine on the market, being customized for each type and being able to build custom headstands. We know in deep the various existing technologies, with their strengths and improvement points.

We manufacture fin rolls for several applications, both in single and twin track versions.

Fin Mills and Headstands

Fin Mill

At JEM we design and build custom machinery for fin forming. We adapt to the production needs of our clients.

In radiator and condenser fin we have three levels of machinery:

  • High Volume Production Machine
  • Medium Production Volume Machine
  • Low Production Volume Machine

We analyse and design tailor-made solutions for all those fins that can be produced with fin rolls.

High Performance

JEM engineers have designed the High Performance program, the result of our commitment to get the best performance from our tools. This program consists of two pillars:

Tool Optimization Program

The performance of a fin roll is not only determined by the quality of the tool, but many other aspects play a role in achieving an improvement.

Our engineers work closely with customer's engineers, becoming an extension of their engineering team. We establish a detailed improvement program and jointly set goals.

This allows our clients to rely on true specialists that are allied and involved with their goals.

High Performance Solutions

With Fin Rolls, we work with three range of materials, each one optimized according to its application.

  • HSS Material: We work with the best steel, and its optimized heat treatment, to form and cut aluminium and copper alloys. Not recommended for working with clad.
  • HP3 Material: The latest innovation from JEM. We use a special HSS with a PVD coating that achieves performance close to carbide, with the advantage of being a less brittle material.
  • Carbide Material: out of doubt this material is made to achieve highest performance. As it is very hard, you must know how to handle it to avoid breakage of the discs. Recommended to clients that have extensive experience in working with carbide.
