Product Description

This device allows a quick check of the hardness of cores and molds made with chemical binders. By means of a special knob, the operator get a milling head in rotation in contact with the area to be inspected ; a digital gauge integrated on the device measures the penetration depth of milling head which is in reverse relationship to the hardness (the harder the mixture the lower the penetration depth of the milling head ). The amount of half -rotations to be ran is conventionally established as five (3 right-side + 2 left-side or vice versa). Depending upon materials behaviour (very hard or very brittle) the amount of half-rotations should be tuned.
