This paper introduces the force-loading control system of C scale of the intelligent loading and laser Rockwell hardness standard device. The dead weights are controlled by rotary-electromagnetic devices and driven by a motor, which avoids the manual switching of the work-ing dead weights. The impress depth of the Rockwell block and velocity of the principal axis are measured by a laser-vibrometer controller. So the Rockwell hardness test is performed automatically. The Depth-Time plot and Force-Time plot are shown automatically on the computer screen dur-ing the test, which accords with the new definition of the Rockwell hardness test.
