Comparing Precision Abrasive Waterjet Machining to Wire EDM

Key wire EDM strengths

• Extremely precise parts are possible [±0.0001" (±0.025mm)]
• Very thick parts [over 12" (30 cm)] can be made
• Intentional taper can be put into a part for die clearance and other uses

Key precision abrasive waterjet strengths

• Up to five to ten times faster depending on part thickness
• No Heat Affected Zone (HAZ), so no need for secondary operations to remove the HAZ or additional heat-treating to compensate for the process
• Works well with non-conductive materials (such as glass, stone, plastic) as well as conductive materials
• Can pierce material directly without the need for a pre-drilled starter hole
• Can produce large parts at reasonable costs
• Simple and rapid programming and set up with minimal fixturing
