Process parameters affecting blast quality
- Initial condition of the component – material and contamination
- Velocity of abrasive
- Size (and shape) of abrasive
- Hardness of abrasive
- Blast wheel location
- Travel speed of part through the machine (cycle time / exposure time)
Follow the path of abrasive:
- Regular inspection is essential
- Commonly blamed on the manufacturer
- Quality of machine manufacture (cabinet design, lining etc.) does play a role
- Common issues: leakage, noise, media consumption
- Machine designs / controls are not intuitive to prompt maintenance
Saves on operating cost if taken seriously
