cut
Check material.
Kerf has pronounced "V" shape
Possible cause Solution
Cutting speed is too fast Reduce cutting speed.
Mixing tube standoff is too great Check standoff; it should be set to 0.10-in.
Abrasive flow rate is too low Increase abrasive flow rate.
Water pressure is too low Increase water pressure.
Rough surface finish
Possible cause Solution
Cutting speed is too fast Reduce cutting speed.
Mixing tube standoff is too great Check standoff; it should be set to 0.10-in.
