The machines are expensive! Although not as expensive as some of the other professional systems out there.There’s usually little or no surface prep required (unless the surface is really rough, like from a sand casting).Usually they’re a fixture in a machine shop, so you won’t lose it (at least I hope not) and you’re less likely to damage it.Super accurate, easy enough to check work within +/- 1 HRC or better, depending on the machine and how well you can support the piece with the anvil.The machine will read the difference in distance between the loads and give an accurate reading. Then you push the button or pull the lever (depending on the machine) and the tester will apply the major load. You preset the minor load and the part will properly seat between the penetrator and the anvil. The machine uses a minor load and a major load to make sure that the reading is accurate. A rounded steel ball or conical diamond tip is pushed into the metal, and the depth of the indent is measured by the machine. This is probably the most common way of professionally and accurately checking the hardness of metals.
