    Cutting everything with one cutting head??

    Hi All, Please can someone answer my question!!?? We cut Mild steel up to 15mm on our 2.2kw bystronic bysprint. Also Stainless up to 8mm. When we bought the machine second hand a year or so ago, it came with a 5" and 7.5" head. The question is... Can we cut everything with the 7.5" head, and...

    Problem cutting 3mm stainless

    Thanks Krugtech, i never knew it was radio waves! Im sure the head is tight on the Z axis. I just cant figure it out. I have noticed when the head comes down it seems to go right down to the sheet (but not dent it or move it) then quickly go back up to the pierce height (say 2mm), pierces, then...

    Problem cutting 3mm stainless

    Hi, Thanks Krugtech for the reply. The ceramics are from bystronic. When you say internal leaks, you mean leaks in the head? cutting larger circles (e.g. 25mm dia) are absolutly fine... so if it was an internal leak would it not affect all circle sizes? When ever i have cutting problems, i...

I then cut this program many times on the same sheet and same parameters etc. One will cut fine, then on another the...

    Laser servicing

    Hi, Im looking for someone to annually service my bystronic bysprint laser, sort break downs etc... I currently have a service contract with Bystronic but this is far too expensive. Im ideally looking for someone in the south west of england, who knows these machines well. Best regards, SJClaser

    Hi all, I am cutting 3mm stainless with a 2.2kw bystronic bysprint but having problems. When cutting holes approx 10mm dia, the head comes down pierces fine, and then cuts around - but, when it is approx half way round the head keeps moving but jumps up slightly and then down again to 1mm...

    Pulse pierce mild steel spraying up!!

    Hi all, thanks for the replys, I think is is standard pulse pierce not not totally sure! I did fiddle the gas pressure but that didn't really help much. I will check the focal position, but the actual cut edge was good so i didn't think it would be this. Im not sure abotu the beam purge...

    Pulse pierce mild steel spraying up!!

    Hi all, if anyone can help with the it would be very much appreciated. I'm trying the cut 10mm Mild Steel on a 2.2kw bysprint. The cut is very good, and clean - but the pulse pierce is not so good. The head comes down and as soon as it starts the pierce it sprays up a load of sparks, then...

    What gas to laser galvanised steel?

    Hi, thanks for all the replys! Can i ask why not oxygen? Ive tried it and got it cutting pritty clean! Does the oxidisation affect how well the galvanise protects the metal from rust? Thanks, SJClaser!
