High-tech specialist summit in Odense

Earlier this spring, specialists from all over the world were assembled at our factory in Odense. Great minds within both CAM software, processing machines and cutting tools were required to reach the finishing line of an unusual task.

The task involved manufacturing a series of tools for the production of steel plates to be used in a new type of fuel cells. Among other things it included 0.4 millimetre of uninterrupted ball milling over several months and tolerances as low as 3 microns.

"We have some of the world's most precise milling machines with built-in cooling in all axis from the Japanese company of Makino that are able to mill extremely accurate. We were therefore convinced that we could do the job," explains Hjerno’s managing director Aage Agergaard.

A task far beyond the ordinary
However, it turned out to be not so easy in practice due to some inaccuracies in the otherwise highly recognized CAM systems that our factory uses.

A system developer from our Chinese CAM-supplier therefore ended up spending two weeks in Odense recoding the entire programme structure to enable the CAM software to handle the extremely heavy files.

At the same time Makino’s specialists came up with suggestions for optimising the milling process, and the Japanese supplier of cutting tools even ended up developing a special kind of cutting tool merely for this specific task.

"It became a task far beyond the ordinary, also compared to what I had anticipated. Therefore, we had to bring together specialists from all over the world here in Odense," says Aage Agergaard.

New order from satisfied customer
In turn the summit had the intended effect. Hjerno’s processing machines now stay within the tolerances, and the client is so happy with the final result that he has placed yet another large, long-term order with us, which most likely will last for the rest of the year.

"We are essentially a tool factory, but it turned out that the specialist knowledge, which we have gained in the field of high precision, may also be applicable in other industries," concludes Aage Agergaard.
