years of engineering
Machine building
Drive and guide components for special-purpose machines.
THE TOLERANCE WE PROMISE
±2 µm
Two thousandths of a millimetre – thinner than a hair. Measured on every part, documented for every batch, so your auditor sleeps as well as you do.
WHAT WE DO
We machine
parts, build
robot cells and keep
your lines running.

SOLUTIONS
Five ways we make machines better.
Hover over a solution to look closer. One team, one contact, one factory – from the first sketch to the spare part in year twenty.
01
Precision components
Turned, milled and ground to ±2 µm – from prototype to 100,000 pieces
02
Automation systems
Robot cells that fit into existing lines
03
Engineering
Design, simulation, first parts within ten days
04
Retrofit & service
Ten more years for your machine, at a third of the price
05
Laser & forming
Cut, welded and formed assemblies in one flow

HOW WE WORK
From first sketch to series production.
One team, one contact, one factory. Nothing gets lost between drawing and delivery.
KERNA IN NUMBERS
Big enough to deliver. Small enough to call back.

INDUSTRIES
Where tolerance decides.
Three industries where a failed part stops more than a machine.
PARTNERS SINCE DECADES
Why machine builders stay.
Kerna solved a tolerance problem our previous three suppliers gave up on. Two years later, not a single complaint.
Martin Keller, Stahlwerk Nord
Head of Purchasing
A family business that thinks in decades, not quarters. That makes them the partner we plan with.
James Carter, Carter Packaging
COO
From first sketch to series in eleven weeks. Their robot cell fitted into our line on the first attempt.
Sofia Romano, Automazione Italia
Project Lead
The retrofit extended the life of our line by ten years – at a third of the price of new machines.
Lars Petersen, Nordwind Energy
Plant Manager
Validated processes, clean documentation and engineers who pick up the phone. Exactly what medical technology needs.
Dr. Anna Weiss, Medica Systems
CTO
