Ernst Grob

Looking forward to the challenges of the future with élan and innovative energy.

Since 1962 we have been developing and building special purpose machines dedicated to the cold forming.

Currently, our product range covers machinery for the cold forming and reduction of splined or smooth component of solid or sheet metal stock, including installations for the slotting of ring or cup shaped sheet metal workpieces.

Our machine concepts also incorporate the GROB cold forming process developed by the company founder Ernst Grob, a globally unique chipless spline generating technology.

Complementing our product range, we also offer a diversity of services dedicated to the cold forming, reduction and slotting processes (subcontracting, testing department, after-sales support, …).

The extensive and broadly based expertise of our team and partners, complemented by decades of in-house ex-perience in these specialist technologies, allow us, in conjunction with you, our customers, to rapidly generate ideal and cost-effective solutions to your specific production requirements!

We are proud that our established customer base includes most major OEMs and systems suppliers within the automotive, commercial vehicle and agricultural machinery industries.

It would be a pleasure to meet you personally and have an opportunity to introduce our processes, products and services first-hand.

Continuous improvement is a key aspect of our corporate mission, products and services. Even as a regular customer, it can be worthwhile for you to remain in touch with us on a regular basis.


Over the past half-century and with the support of our loyal customers and dedicated employees, the company has successfully developed into a global leader in the manufacture of cold forming and slotting machines.

In keeping with our claim of continuous improvement and convincing our customers with new, progressive technological solutions, we are looking forward to the challenges of the future with élan and innovative energy.
