Grinding and Abrasives Quality Testing
Non-destructive quality testing and material characterization for grinding wheels and abrasive products using vibrational analysis.
Author: Flowzy
Overview
GrindoSonic serves as a quality testing and material characterization tool for the grinding and abrasives industry, utilized by manufacturers and research institutions. The system leverages over six decades of specialized knowledge to provide easy and fast testing features with comprehensive data collection options.
Non-Destructive Testing Advantage
Unlike destructive methods such as bending tests or sand blast evaluation, the technology employs non-destructive vibrational analysis. This approach enables:
- Repeated testing on single samples
- Rapid 100% quality control across production runs
- Sample preservation for reference
- Trend analysis over time
Material Properties and Performance
Grinding material characteristics directly influence grinding process outcomes:
| Property | Performance Impact |
|---|---|
| Hardness | Wear resistance |
| Strength | Burst resistance |
| Grain quality | Cut quality |
| Grain size/form | Surface finish |
| Binding properties | Wheel life |
| Porosity | Coolant flow, chip clearance |
| Density | Overall performance |
Process-Induced Defects
Heating and curing processes can introduce cracks and micro-cracks that affect product performance. Critically, all of the above factors including cracks and micro-cracks have an influence on the fundamental vibrations of a grinding product.
How It Works
The technology measures vibrational responses following light elastic impulses:
- Impulse application: Light tap excites vibrations
- Frequency measurement: Sensors capture resonant response
- Property calculation: Software determines elastic properties
Hardness, binding and structure of a grinding product correlate with fundamental frequencies generated through the impulse excitation method.
Calculated Properties
- Young’s modulus
- Poisson’s ratio
- Internal damping characteristics
Deployment Options
- Desktop laboratory equipment: R&D and incoming inspection
- Fully automated in-line systems: 100% production testing
- Data transfer capabilities: Integration with computers and PLCs
This enables comprehensive quality surveillance from development through production.
