- ADVANTAGES OF WATERJET CUTTING OVER LASER CUTTING
|
- Can cut many materials laser cannot
- Gives the same or better tolerances/accuracy
- Can cut thicker materials
- Makes uniformity of material less important
|
- ADVANTAGES OF WATERJET CUTTING OVER EDM CUTTING
|
- Is much faster.
- Is able to cut wider range of materials.
- Makes uniformity of material less important.
- Does not heat the surface.
- Creates no heat – affected zone.
|
- ADVANTAGES OF WATERJET CUTTING OVER PLASMA CUTTING
|
- Produces a nicer edge finish.
- Does not heat the part.
- Is more precise.
|
- ADVANTAGES OF WATERJET CUTTING OVER FLAME-CUTTING
|
- Produces a nicer edge finish.
- Does not heat the part.
- Is more precise.
|
- ADVANTAGES OF WATERJET CUTTING OVER MILLING CUTTING
|
- Needs no tool.
- Can machine brittle, pre-hardened and difficult materials.
- Can produce more parts out of same material.
|
- ADVANTAGES OF WATERJET CUTTING OVER PUNCH PRESS CUTTING
|
- Is better on thick materials.
- Is better on brittle materials.
- Is better on hardened materials.
