Hjerno invests in a new circular grinder

Due to a growing demand for circular grinding in connection with tool manufacturing, Hjerno is investing in an advanced new CNC circular grinder to supplement the factory's existing circular grinder.

This is a ZR 600 CNC circular grinder from the German manufacturer Ziersch, and the machine can handle samples up to 450 millimetres in outside dimensions. In addition to the machine itself, Hjerno has also purchased a wide range of accessories.

“We see a tendency that we receive more and more orders that include circular grinding. We are now drawing the necessary conclusion by investing in a new machine that triples our capacity and at the same time gives us higher flexibility,” says Managing Director Aage Agergaard.

He points out that, among other things, the machine can be operated by Hjerno's new permanent evening shift.

High degree of preprogramming
The circular grinder will also be applied to grinding tasks where a precision of a few micrometres is required. For these tasks, a traditional circular grinding can ensure a better result than high-speed milling, which is also often used for round tool parts.

Aage Agergaard states that the CNC functionality is an important parameter, as it allows for preprogramming the machine and thus to a greater extent for planning the production and for ensuring the lowest lead times possible. 

“At the same time, the new generations of CNC machines are so intelligent that they can perform process monitoring themselves. This means that there are more employees, who can operate these machines than before, which also increases flexibility and facilitates use. ”

A short way from thought to action
The new circular grinder is scheduled to arrive before the end of the year.

“It's far from a cheap investment. But this is a good example of how, with the new ownership with Vækstpartner Kapital, we realise our ambitions for continued growth and do not shy away from investing in new technology that can strengthen our business, even though the payback time for these types of machines lies far on the horizon,” concludes Aage Agergaard.
