Applications
Design Considerations:
Applications
20 min – Includes Setup & Cleanup Time
.5” hastalloy +/-.002” Tolerance
Design Considerations:
Edge Finish
Edges have a sandblasted
appearance
Harder materials exhibit better
edge finish
Finishes will range from 63 RMS to
very coarse depending upon the
application
Eliminates grinding and polishing,
reducing secondary operations
costs
Design Considerations:
Why use Water Jetcutting?
Eliminates pre-drilling
Narrow kerf allows tight
nesting
Cuts all types of materials
Accurate cutting of soft
materials
Cuts thick materials
