Why Use Waterjet Cutting?
Advantages over LASER:
-
Cuts up to 6" thick material
-
No issues with reflective materials such as brass, copper, aluminum
-
NO HEAT INPUT
-
No heat-affected zone (HAZ)
-
Hardened materials can be cut without changing temper
-
Can cut heat sensitive materials like
-
plastics
-
rubber
-
composites
-
-
-
Waterjets can also cut materials like wood, glass, stone, concrete, and very hard ceramics
Advantages over:
Milling
-
Minimum setup and fixturing time
-
Easier to program and cheaper than milling
-
Waterjet typically much faster cutting process
Plasma/Oxy-fuel
-
Both are a very hot process which adds a great deal of heat to the product leaving a HAZ
-
Much better surface finishes with waterjet. Practically no dross on backside of part minimizing secondary operations.
-
Waterjet parts can be nested much closer together compacting sheet sizes and maximizing material usage

Design Tips For Waterjet
-
Tolerances +/-0.005 on most parts. By running slower feed rates certain parts can be +/-0.002
-
Minimum hole size of .090" diameter
-
Square inside corner geometry will cut to a .020" radius
-
Larger inside or outside radius corner will cut slightly faster (lower cost)
-
Maximum material thickness is 6"
-
Maximum sheet size is 6' x 12'
Sending Part Drawings:
E-mail a 2d DXF file. Include in the email:
-
Part quantity
-
Material
DXF File Tips:
-
Only include the part geometry that will be waterjet cut (perimeter and through holes/cut-outs), no dimensions, notes, etc. needed
-
Add a 1" x 1" square with and "X" near the part geometry(used for scaling)
-
Double check for broken or overlapping geometry
Note : If your part will require additional machining or forming other than just waterjet cutting, include a PDF file of the dimensioned part drawing
PDF File Tips:
-
Generate a PDF file of your part drawing from your CAD software
-
Standard 3 view shop drawing which can be printed on our end
-
The drawing would have all the needed dimensions (in inches), tolerances, and notes to make the part from
Other Acceptable Methods:
-
Fax, or mailed drawings/sketches.
-
Could also be an actual part. These methods may incur additional engineering charges to generate the DXF geometry
