GrindoSonic® SA Semi Automatic system for 100% production Quality Control

The GrindoSonic® SA system combines Impulse Excitation with an automated vibration measurement arm to be able to measure large amounts of products in a semi automated way. A fully automated measurement can be realised by loading and unloading the instrument by means of a 3D manipulator or robot arm.
The natural frequency measured is an overal Quality parameter integrating hardness, presence of cracks, structural integrity, compound gluing quality and dimentional tolerances.
