Fiber Laser Cutting Machine have become very popular in most metal cutting factory. Several years ago, only some big metal cutting factory use fiber laser cutting machine as it is very expensive machine. Recently years, more and more small factory use fiber laser cutter replace old cutting tools. As machine cost is much more lower, may be only 30~60%. Additional, fiber laser cutter’s running cost is the lowest.
Of course, although fiber laser cutter have very low running cost, but it is not mean no consumable parts.
Consumable of Fiber Laser Cutting Machine
1. Electric Power
Electric power is necessary for all machine. Laser cutting machine’s electric power cost total include three parts, include laser source, water chillier and servo motor.
1000w laser cutting machine for reference.
fiber laser’s photoelectric conversion is 25%, which is the highest in all laser machine. One set 1kw laser source will cost 4kw/h. 1000w fiber laser machine’s water chillier need use 3kw/h. Servo motor and machine bed parts total need about 4kw/h. So if one 1kw laser machine running in full power its electric power cost is about 11kw/h. Actually one machine’s real cost only use 60% power as these parts is not running always. In this case, its real cost is about 6.6kw/h. But one set 1000w co2 laser cutting machine’s power cost will be several times.
2. Auxiliary Gas
Usually we use O2 gas when cut mild steel and N2 gas for other material, such as stainless steel, aluminum and brass. For example, when we cut 1mm stainless steel, it need about 12kg/hour N2. When we cut 5mm mild steel, it need about 9kg/hour.
3. Quick wear parts
Fiber laser cutting machine’s quick wear parts all on laser cutting machine, include protective lens, focus lens, nozzle and ceramic ring. Protective lens and nozzle’s lifetime is about 1 month/piece. Focus lens’s lifetime is about 3 months/piece. ceramic ring’s lifetime is about 1 year or more.
Except above parts, fiber laser cutting machine nearly have no other consumable parts. Compared with other cutting tools, its cost is very very low. So more and more people select fiber laser cutter with its price’s decline.
