IPG 500, 1000, 1.5kw, 2kw fiber laser cutting machine with Safety CabinetCutting machine are widely used in sheet metal industry, this article will compare various advantages and disadvantages between fiber laser cutting machine and YAG laser cutting machine:

  1. Fiber laser has significant of operation and maintenance.
  2. Scope of work: optical fiber not only contains the YAG laser cutting speed and area, has better performance on the cutting quality;
  3. Fiber laser cutting function in small power can achieve the effect of high power, reduce the cost of the cutting, with low energy consumption, achieve high efficiency.
  4. The main advantage of the existence of its optical fiber cutting machine transmission medium and light; optical fiber laser diode as light source in the optical, fiber as transmission medium, with no loss of light energy transmitted to the laser cutting head.

Because of fiber cutting machine has such advantages, industry demand for its constantly improve, in demanding higher industry to obtain the very good application, has realized the real fine cutting. Completely replace the traditional laser cutting machine.

Fiber LaserNd: YAG Laser
Reliability50,000 -100,000 hours500 – 1,000 hours (lamp-pumped)

10,000 – 20,000 hours (diode-pumped)

Power Consumption170W per hour6kW per hour
Maintenance·   No maintenance
