Troubleshooting Part
Quality
Abrasive Delivery System
The abrasive flow directly affects machine cut performance
Check the condition of the following:
1. Dwells times
• Control jet on/off timing for each pierce
• Improper timing can cause the abrasive system to clog or cut poorly
2. Orifice size and condition
• Change the water volume exiting the cutting head
• Too much volume leads to water in the abrasive line
3. Abrasive line air leaks
• Air pressure loss affects abrasive flowrate
• Replace abrasive tubing if worn of damaged
4. Improper metering disk size
• Can starve or choke the system; Use the proper size
Part Quality
Poor cut quality is generally caused by improper settings or
the wrong edge quality selected
Verify these setting are correct in FlowCUT:
1. Orifice size
2. Mixing tube size
3. Cutting pressure
•
Pumps with mechanical pressure
controls must match the pump gauge
pressure to the value input in the
setup screen
4. Abrasive flowrate
Sample jet setup, Your settings may be different
High-pressure Leaks
Weep holes help identify issues
• Located on all high-pressure fittings throughout
the system
• Leaking weep holes will damage
high-pressure components
High-pressure component failure and leaks cause
pressure loss during cutting and will affect part quality
