Hi,
What wouild you like to know over the maintenance.
We do service on allmost every brand lasers, trumpf, bystronic, mazak, amada , panasonic, WB laser, rofin...
3,5 euro / hour for minimum maintenance, and 5 eur / hour for excellent maintenance, just internal mirrors, turbo blowers etc ... not power consumption, cutting gas ..
Turbo blower need to be changed around 12k hours,
tubes also.. but not expesially needed, when they have dielectric breakdown the power supply gets an error.
power supply only changed when broken.
It is better to change all fans and turbo blower after 12k hours.
I dont know where you are...
