SYSTEM FOR HARDNESS TESTS OF LARGE FORGED PARTS WITH THREE-DIMENSIONAL HEAD MOVEMENT
Quality control is a major requirement in the metallurgical industry and the hardness test, usually a Brinell 10/3000 test, is an integral part of the production process of forged, rolled and heat-treated products.
Easydur has always been at the forefront in the design and construction of special hardness testers for such production needs: the range of hardness testers with integrated surface preparation milling is one of the flagships of the company.
However, at one point the R&D unit of Easydur decided it was time to take this technology to the next level.
The breakthrough was reached thanks to an Easydur patent consisting of an innovative hardness testing head with three-dimensional movement
All the features of the multi-slot head (surface cleaning, different indenters and auto-focus lenses) can now be exploited to the full, to perform hardness tests on the top and the sides, at any angle and even upside down, on parts of all sizes and shapes, including the most complex.

MAIN APPLICATIONS OF THE THREE-DIMENSIONAL HEAD HARDNESS TESTER
This system finds its perfect application in portal or semi-portal hardness testers with X, Y, and Z CNC axes that can be programmed to reach any test area.
Each Easydur hardness tester is designed to the precise specifications of the customer. In case of the portal hardness testers, a solid structure capable of accommodating parts weighing tens of tonnes can be built without the slightest effort.
Normally, when testing the hardness of small components, the most obvious solution for testing different areas is to turn the part. However, this can be a time-consuming and difficult operation when the part in question is a large forged piece.
Once the part has been positioned and the desired position programmed, it will be a simple matter of pressing “Start”: a Brinell 10/3000 hardness test inclusive of surface preparation and autofocus indentation reading will be completed in just 45 seconds.
Easydur has turned hardness testing of large forged components into a real production process, and continues to innovate day after day to achieve the highest possible level of automation.
