Two new high-precision machines increase capacity

In our constant efforts to reduce throughput times in production and at the same time deliver ultra-precision tools at a reasonable price, we at Hjerno regularly invest in new technology for our production.

The latest additions to the machine park are two highly precise machines, which have just been installed in the factory.

These are a high-speed milling machine and a die-sink EDM machine - both from Makino and both characterised by a very high degree of precision.

"The machines have been purchased to increase our production capacity, but they’ve also been acquired to gear the machine park to produce ultra-precision tool components, which don’t require subsequent adjustment. In this way, we reduce the throughput time and at the same time assure the customer a better total price for the tool, as the tool works from day one," explains Managing Director Aage Agergaard.

High-precision processing wins through

The purchase of two new machines should also be seen in the light of Hjerno’s increasing focus on making the non-moulding tool components as precise as possible.

"There was previously more focus on ensuring a high level of precision in the moulding cavities and other components of the tool. But we have optimised this for a large part of all tool components. Because the more precise all tool components in the tool are - also the non-moulding components - the more durable the complete tool becomes. With the result that there are far more rounds with perfect parts in our tools," explains Head of Production Kristian J. Hansen.

This can be seen, quite specifically, in the fact that Hjerno’s production department now houses more high-precision machines than high-volume machines that process coarse shavings.
