Verifying Grinding Burn! Our Inspection Process

We analyse your parts for thermal rim zone damage. Irrespective of whether this analysis is carried out on site at your company or in the testing laboratory, we can provide you with professional and objective expertise.

 

Non-destructive tests:

TestAbbreviationPrincipleBasicsTypical Faults
Radiographical testRTelectromagneticEN444, EN13068, EN16016Foreign inclusions, pores, cracks, bonding errors
