A Comparison of Laser, Water, And Plasma Cutting

Many users are often confronted with the question of what cutting is best. Since the advantages of these cutting processes come into their own depending on the requirements and the material. These cutting machines can be purchased from different laser cutting machine manufacturers.

However, these methods are not in competition with each other but form a meaningful affiliation in many manufacturing processes.

Here you will find information on the most important features of these machining processes!

Cutting With Laser:

The Advantages:

  • High cutting speeds
  • Optimum freedom from burrs
  • Low heat impact
  • Perfect dimensional accuracy
  • Best use of material
  • Short processing times
  • Minimum cutting gap
  • A large variety of materials

Disadvantage: 

  • High investment costs
  • Limited material strengths
  • Process instability when mirroring

Cutting With The Water Jet:

The Advantages:

  • High profitability
  • A large variety of materials
  • Optimum use of material
  • Small kerf width
  • No thermal stress
  • Cutting thick materials
  • High precision down to the micron range
  • Often no post-processing is required

Disadvantage: 

  • High operating costs
  • The great risk of corrosion
  • Slow cutting speed
  • Treatment of the cutting water
  • Disposal of the abrasive

Cutting With Plasma:

The Advantages:

  • Without alternative in the middle steel range
  • High quality in medium strengths
  • Cutting high-alloy steels

Disadvantage: 

  • High operating costs
  • Relatively wide cutting gap
  • The highest noise level
  • Hardening of the edge zones
  • post-processing required

Conclusion

Depending on the cutting task, the advantages of the individual processes come into their own and together form a sensible alliance for a wide variety of applications.
