Design Considerations: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-drillingNarrow kerf allows tight nestingCuts all types of materialsAccurate cutting of soft materialsCuts thick materials Titanium – 15” Inconel – 12”

Advantages/Disadvantages

Advantages: Cuts all materials No part distortion No heat affected zone Cut intricate shapes Tight tolerances Easily programmed Non-toxic

Disadvantages Start-up Cost Noise Pump Maintenance Water Filtration Slow Cutting Rates
