Why should I use waterjet cutting over
lasers?
Laser cutting is a very productive process and
certainly has its place. However, waterjets do have
several advantages over lasers:
-
No
thickness limitations.
-
No
problems with reflective materials such as brass
and aluminum.
-
No
heat input, so there is no burning or
heat-affected zone (HAZ).
-
Waterjets can cut materials which are heat
sensitive such as plastics, rubber or
composites, and even such materials as glass,
stone and very hard ceramics.
-
When you change materials, the only thing you
change is the cut speed. There are no gases,
optics, or anything else to change.
-
Multiple heads are easily added for increased
production.
-
Maintenance on laser equipment is more
specialized and more difficult to perform.
-
Stand off distance between nozzle and material
is not nearly as critical.
-
Waterjets typically require less of a capital
investment than lasers.
