Aftermarket shield for Bystronic laser cutting heads. Replaces Bystronic 2-08700, the copper disc that also appears in parts lists as the signboard or connector base.
The shield sits at the bottom of the head around the nozzle and takes the heat and spatter thrown back off the sheet, protecting the parts above it. A shield that is pitted, warped or covered in spatter should be changed with the nozzle.
Copper, 52 mm across and 8 mm high, with a threaded centre and a knurled edge for hand tightening. Sold singly.

Applications & use cases
After a head collision
A crash bends or cracks the parts at the bottom of the head first. A spare on the shelf gets the machine cutting again within minutes.
Nozzle will not centre
A worn seat or thread lets the nozzle sit off centre, which shows as cut quality that changes with direction. Replace the worn part before re-centring.
Planned maintenance
Check the bottom of the head at every nozzle change and replace parts that are pitted, burred or loose.

Frequently asked questions
Will it replace my Bystronic 2-08700?
Yes, it is a direct replacement for the Bystronic 2-08700 with the same fitting. If the number is worn off, it measures 52 mm across and 8 mm high.
How often should I replace the Bystronic 2-08700?
Laser and plasma nozzles wear in days to weeks, depending on hours of arc or beam time, material and gas. Change it on condition, not by date.
What are the signs the shield needs replacing?
An oval or nicked orifice, spatter stuck on the tip, more dross, a wider cut or bevel on one side, and height sensing errors.
Why does the machine show a sensor error after changing it?
On laser heads, a cracked ceramic ring or a loose nozzle breaks the capacitive height signal. Check that both are seated and clean.
What should I do after changing it?
Centre the nozzle on the beam and recalibrate the height sensor. A new nozzle off centre cuts on one side only.
Is this a genuine Bystronic 2-08700?
No. It is an aftermarket shield made to replace the Bystronic 2-08700. It is not made by the original manufacturer; the number only shows what it replaces.
