Crankshaft Hardness Testing

Function

In collaboration with QATM, we have developed a hardness testing system that enhances the ergonomic aspects of crankshaft testing for a renowned engine manufacturer in Austria. This is particularly beneficial as the test points are often in hard-to-reach areas. At the core of the system is a floating eccentric testing device, developed by Makkon, which enables HRC 150 (Rockwell) hardness testing to be performed on all four quadrants of the main and journal bearing positions.

The various crankshaft types of the manufacturer are securely clamped between centers, similar to a lathe setup. The testing equipment can be manually, easily, and quickly positioned at the test point. The testing process is fully automated within the floating clamping fixture. Adjacent to the hardness testing unit, QATM has positioned production-representative standard machines for side cheek and sprocket wheel testing.
