This control method provides the ability to determine whether the recipe accepted for a given designation is observed.
The method for controlling the hardness of an abrasive tool is based on determining the speed of propagation of acoustic waves (speed of sound Cl), which is closely related to the recipe characteristics of abrasive wheels, their performance indicators, and can be quickly and accurately calculated from the results of measuring the frequencies of natural vibrations (CSF) of the controlled product ...
The use of the acoustic method to control the physical and mechanical properties of an abrasive tool is regulated by the state standard DSTU GOST 21963: 2003 "Cutting wheels. Technical conditions".
Hardness is one of the main characteristics of abrasive wheels and therefore needs to pay more attention to its control.
