GrindoSonic® MK7 measuring technology enables you to map the full mechanico-elastic fingerprint of components and assemblies and assure:
Consistent quality of parts and (sub)assemblies
Mechanical performance measurement
Optimizing manufacturing processes
For determining the elastic properties of Precision Mechanics Parts (metals, sapphires, ceramics,… ), the Impulse Excitation Technique (IET) is widely described as a test method in many standards (ASTM E1876, 1548-02, C1259-01, DIN EN843-2, CEN N422, ISO 17561, etc.) In this respect, GrindoSonic MK7 systems are stand-alone devices returning the E-modulus, G-modulus, Poisson’s ratio, Porosity and Microcracks instantly by an easy “Tap and Read” method, based on the resonance frequency profile of your material samples.
The firing or the sintering process of ceramic products has an important influence on the mechanical properties and will become visible in the mechanico-elastic properties of the products.
In short, material composition, firing and finishing steps (polishing, rectification, grinding, heat treatments, hardening, …) are critical manufacturing processes and can be controlled and optimized using the GrindoSonic IET measurement systems. Before and after each manufacturing step, the resonance frequency profile can be determined whereby the delta allows you to calculate the process stability.
Also cracks and microcracks can be detected as they will cause an increased damping of the resonance frequencies.
