Cut part quality issues
Cutting speed is slower than it should be for a given surface finish and kerf width
Possible cause Solution
Insufficient abrasive flow Make sure the abrasive flow rate is set correctly.
Insufficient water pressure Make sure the pump is providing proper pressure.
Mixing tube standoff is too
great
Check standoff; it should be set to 0.10-in.
Different target material
properties
Check for consistency of target material.
Abrasive is too fine Use a coarser grade of abrasive.
Damaged or worn orifice
Check integrity of the waterjet stream. Inspect orifice; replace if
needed.
Cutting speed is lower than normal; kerf is too wide
Possible cause Solution
Mixing tube standoff is too great Check standoff; it should be set to 0.10-in.
Mixing tube's ID is too large or the
mixing tube is worn out
Make sure that the correct size mixing tube is installed.
Replace worn mixing tubes.
Damaged or worn orifice
Check for a flaring waterjet stream. Inspect orifice;
replace if needed.
