why waterjet vs milling

• There is only one tool to qualify on an abrasive jet
• Setup and Fixturing typically involves placing the material on the table with a waterjet
• Cleanup is much faster with an abrasive jet
• Programming is easier and faster
• Machine virtually any material, including:
  • brittle materials
  • pre hardened materials
  • otherwise difficult materials such as Titanium, Hastalloy, Inconel, SS 304, hardened tool steel....
• Waterjets are used a lot for complimenting or replacing milling operations.  They are used for roughing out parts prior to milling, for replacing milling entirely, or for providing secondary machining on parts that just came off the mill.  For this reason, many traditional machine shops are adding waterjet capability to provide a competitive edge.
