Flying shear - GIF

I went to An Auction in China back around 2008 in the auction there was a "C" & "Z" purlin roll form made in Germany up for bids it had 27 rolling stations and the new Chinese mills had only 15 forming steps. We bought a new Chinese roll form with all shear die sizes from 90mm "C" through 200MM"C" and they almost gave us the one from Germany I think Saad only bid the equitant of about $5,000.00 for it and no other bids were turned in as no one wanted an older machine I think he only bid on it because I told him I could make a better machine out of something 20 years old than a brand new one would be. once both machines were shipped to Kuwait and we set them up I had some guys replace a lot of bearings on the old machine the rollers were worn from years of service so we put them in a lathe with a large tool post grinder and re ground them the old machine couldn't run meter for meter of the new machine but it could roll 3mm thick material just a little thicker than 12ga. the new one only 2mm thick the hydraulics on both flying shears worked much better once I installed 10 liter accumulators on them to have a stored ready pressurized volume for travel and shearing
