Common Questions of Fiber laser cutting machine

1.Is the laser power adjustable, can it go way down to say 50W for engraving?

Seems you did some research before,yes,indeed,some customers asking for marking using cutting machine,here sharing with you some working videos: (Please note that only for metal surface marking not deep engraving).

But we do not recommend you using cutting machine to do marking works,it is expensive,reasons as follow:

• 1.Cutting machine power at least at 15kw,while small marking machine at 800w,so High cost of electricity;
• 2.Cutting machine need Auxiliary gas,such as N2 for aluminum,while small marking machine no need,so High cost of Auxiliary gas;
• 3.Cutting machine has consumables on cutting head,such as nozzle,protective lens,while small marking machine has no wearing parts,so the using cost is higher.

2.what is running cost of Laser cutting machine?

The running cost includes 3 parts: electric power, auxiliary gas and spare parts.

1. Electric power  
1.5kw n-Light 6060 model fiber laser cutter rated power about 18kw.
​Real machine running cost takes 60%~70% of whole power, so the real electric power cost is 10.8-12.6kw/h.

2. Auxiliary gas consumption (Just FYI)
One gas tank is 40L in China.

1). Nitrogen consumption is the same for different thickness stainless steel and aluminum.
Its consumption of continue cutting is about 20~30min/tank.

2). Oxygen consumption will decline when carbon steel thickness increase.
The thicker the carbon steel, the less the gas consumption.
For example, 1mm carbon steel cutting gas consumption is about 50~60min/tank.
10mm carbon steel cutting gas consumption is about several hours/tank.

We recommend you use liquid gas, its cost will be much lower. Most of our customers use it.

3. Quick wear parts
Main quick wear parts include nozzle and protective lens.
First year their consumption is about 20~30 pieces, but the cost will decline later.
As their consumption have big relationship with workers’ operation.

Nozzle 10USD/piece; Protective lens 15USD/piece.
So the cost of nozzle and protective lens is about 500USD the first year.
(We will offer 10 nozzles for free.)

4. Other parts.
Focus lens,  collimating lens and ceramic rings are not common quick wear parts.
We recommend you to prepare 1 set for spare, their total cost is 320USD.
