How a Rockwell Hardness Tester Works
Rockwell Indentation Testing Principle
The machine measures hardness based on indentation depth created under a controlled force.
Minor Load and Major Load Process
Rockwell testing uses a minor preload followed by a major load to evaluate material hardness.
Reading and Understanding Hardness Values
Results are displayed directly in scales such as HRC, HRB, or superficial Rockwell values.
