Questions & answers
What is GrindoSonic?
“GrindoSonic is a Belgian manufacturer of non-destructive testing equipment based on Impulse Excitation Technique (IET). Founded by Joseph Lemmens in 1966, GrindoSonic has shipped over 1,700 systems to 50+ countries. The instruments measure elastic properties including Young's modulus, shear modulus, Poisson's ratio, and damping from a single tap, without damaging the sample.”
What is Impulse Excitation Technique (IET)?
“Impulse Excitation Technique (IET) is a non-destructive test method standardized under ASTM E1876. A light mechanical tap excites a sample's natural vibration frequencies, which are captured by a sensor and analyzed to calculate elastic properties (Young's modulus E, shear modulus G, Poisson's ratio, and damping) in under one second with 0.1 ppm resolution.”
What materials can GrindoSonic test?
“GrindoSonic systems test virtually any solid material: metals and alloys, advanced ceramics, refractories, composites, polymers, concrete, glass, carbon and graphite, natural stone, sintered materials, and additive manufactured parts. The technique works on samples from a few millimeters to large structural components.”
How does the GrindoSonic In-Line System integrate with production lines?
“The In-Line System connects to your PLC via the IL Box interface, which handles bi-directional communication: triggering measurements, receiving GO/NOGO signals, and logging data. It supports PLC and OPC-UA protocols for integration with modern manufacturing execution systems.”
How fast is the In-Line System?
“A full test cycle (excitation, measurement, analysis, GO/NOGO decision) completes in under 1 second. That speed allows 100% inspection of every part on high-speed production lines without bottlenecks.”
What types of production defects can the In-Line System detect?
“Any defect that shifts resonance frequency or damping: cracks, porosity, incorrect microstructure, wrong material composition, dimensional deviations, and incomplete heat treatment. Manufacturers use it for 100% inspection of gears, bearings, brake discs, valves, and turbine blades.”
Does the In-Line System require operator intervention?
“No. Once configured, the system runs 24/7 without operator input. The external impulse device delivers consistent excitation, the MK7 processes the signal, and the IL Box sends the GO/NOGO result to the PLC.”
