    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...

    Rumbling

    Hi All, Just trying to work out do many people use 'Rumblers' to rumble laser cut parts after cutting and before despatching them? If so is this to stainless parts, mild steel parts etc... or all parts??? thanks, Sjclaser.

    Problem cutting 3mm stainless

    Hi all, Thanks for your replies. Right I have finally done some more tests and I am sure it is not the code. I nested 1 of the parts (disc 3.5mm I/d 12mm o/d) on a small blank. 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

    Problem cutting 3mm stainless

    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!

    Problem cutting 8mm stainless

    Hi all, some advice please!! Thank you in advance! A few weeks ago i cut 8mm stainless on our 2.2 kw bystronic, using default settings, and had a brilliant cut - no burrs or anything! I am now trying to cut some again and the cut edge is still brilliant but there are massive (approx 3-5mm...

    MDF laser cutting

    Thanks for the reply. I'm aware of the safety aspects and will only give it a go once adequate ventilation is put in. Thanks, sjcLaser

    Changing the head lense?

    Hi All, Thanks for the replys! I hope to reduce the number of lenses i am using. I've only had the laser about 2 months and it started with a new 5" lens. After 2months, running 3-4hrs a day (5days/wk) i am on the third lens which seems like too many. Apparently a new install may cause you to...

    What gas to laser galvanised steel?

    No, not tried air as we don't have a high pressure line and compressor. Just Oxygen and Nitrogen.

    What gas to laser galvanised steel?

    Hi all, I am just wandering what gas is best to cut galv steel sheet? Oxygen is cheaper to cut with due to the lower pressure requried, but the cut quality doesn't seem to be as good on galv. I have been getting a very clean cut on 3mm galv steel using Nitrogen. Should i be able to use oxygen...

    MDF laser cutting

    Hello, I am looking to cut MDF on a 2.2kw bysprint. I am looking for some advice regarding doing this such as parameters etc. Also, if its 6mm MDF, would you sent the material thickness to 6mm, and turn of height sensing..? Im fairly new to this and not sure if when the head comes down will it...

    Changing the head lense?

    Hi All, I have recently started using my first laser, a Bysprint 2.2Kw machine. I am looking for some advice on how often the lense in the head should be changed. Bystronic say take it out and clean it every shift and if there are ANY marks which do not come of then you should change the lens...
