Disk springs for collet chuck Tornado 80

[nik_chris]

Hello everybody,
I need help for a Tornado 80 with collet chuck only.
The clamping of the part in the collet was very poor and after I disassembly the Pratt Bernet I found the the disk springs inside the cylinder was broken.
The cylinder is obsolete and I can not find any spares?
Did anyone had the same problem?
Thanks in advance
Chris
