Hello everyone!
I have bought a new Fiber Laser metal cutting machine two months ago - GN NCF 3015 E - 700W. Its with IPG generator and USA LaserMech Professional Cutting Head /LM. The machine quality is very good (for those who will ask me), and the manufacturer is trusted - there was no problem with the order and the delivery.
I have a 100W Co2 laser for 4 years, but the things with the Fiber and metal cutting are a bit different.
The guy that installed the machine, have set the cutting parameter for SS and CS for the different material thickness, but I am not happy with them... The gas usage is too big (especially nitrogen), and the cut quality is not the best. I have tried to modify these parameters and I get better results, even with less gas usage. Trying to optimize each parameter by myself is a difficult task and it takes a lot of time. So I decided to write here for your help.
I want to optimize these perimeters for quality the best cut quality and gas consumption.
I know every machine can have different parameters for best result, but i want to navigate me trough the main logical things to look for when defining the:
- focus distance for CS
- focus distance for SS
- cutting speed CS
- sutting speed SS
- power settings for SS and CS
- gas pressure - Oxygen
- gas pressure - Nitrogen
- following distance
Something i don't like in this machine - you can't set the nitrogen pressure from the software - just from the reducing valve... And its blowing all of the time for some reason (the option to close the gas while its not cutting is not working). It opens the gas at the begining of the program, and close it after it finishes. I think this is an software issue.
I have some other questions, but maybe in another thread
I'm sure this will be helpful for a lot of people working with fiber laser, or these who want to buy one.
Thank you, and like every man from Bulgaria says - sorry for my bad English
Best regards,
Lazarov
