Troubleshooting UltraPierce by symptom
Delamination or breakage on the part's top surface
Abrasive is not getting to the cutting head before the the water turns on. Increase the
After abrasive on
dwell time.
Delamination or breakage on the surface around the pierced exit hole
Damage at the exit hole is a function of the pressure used to pierce the material—it is not related to
vacuum assist operation. Decrease the pierce pressure.
Clog during normal cutting
• UltraPierce is leaking—this causes insufficient vacuum levels in the cutting head, so that it
cannot draw abrasive properly. Find the leak and repair it.
• Abrasive feed rate it too high—lower the feed rate.
• Check the pinch valve tubing for holes or tears and replace if needed.
Clog during piercing
• Increase the air pressure to 5.5 bar (80 psi) or greater.
• Check the pinch valve tubing for holes or tears and replace if needed.
During calibration, vacuum gauge does not read 0–5 Hg.
The eductor sleeve has worn out—replace the vacuum pump.
