Reaching those hard areas other testers
can not
Sometimes, users of Brinell hardness testing systems find they cannot access all component areas, but a Rockwell hardness test indenter can, says a supplier.
The Rockwell test has improved both the accuracy of hardness testing and the variety of components that can be tested for this top UK maker of commercial grass and hedge cutting equipment Previously, McConnel used a 3000kgf Brinell machine but its ball indenter could not reach many test areas on splined hubs, drive shafts, bolt faces, cutting edges, etc, while the optical measurement of indentations was interpreted differently by different operators

Stainless steel robotically hardness tested
Believed to be the first that a digital Vickers hardness testing machine has been adapted for robotic operation, a system has been configured for a Spanish stainless steel plant.
Simultaneously Vickers test up to twelve surfaces
No less than nineteen different specimens can be supported for hardness testing by a single fixture developed by Indentec.
These serious shortcomings meant that some hardnesses were impossible to establish to official standards.
One of our benchtop 8150 LK's has completely solved both problems.
The nose mounted indenter enables McConnel to Rockwell test areas inaccessible to the Brinell and do so without special tooling, a big plus.
Additionally, with hardness calculated automatically and shown on a clear read out, there is no room for any human error or inconsistency.
Used for both Rockwell and Rockwell Superficial, the 8150 LK has greatly widened the range of assemblies and components that can be hardness tested with precision and confidence at McConnel's factory.
It joins the Brinell system in making random tests to BS EN standards on specimens ranging from tools, gears, hubs, forgings and castings to incoming steel supplies.
McConnel, which has the Queens award for Technology, is delighted with the performance, seeing the upgrade in quality control as important to its continued success in world markets.
