We are scheduled to replace all the bronze bushings in this machine. Going over the drawings I noticed material designations I have never encountered before.
One is an Rg13 which I thought was common 660 bronze until...

i'm looking for a formula or calculator for minimum center hole diameter to workpiece weight.
we use a 70 degree center, and work piece weight runs from 1/2 ton to 80 tons.
i need something to convince our customer base to agree with changing something we have all over looked over the years...
i am looking for design information on large liquid nitrogen cryogenic deep freeze boxes used in the heat treatment of large steel forgings.
my main concern is the system used to transfer the temperature of the LN2 to the forgings in the container.
it doesn't seem practical to attempt to bathe...
i'm located in west central ohio, and i need to find a company that can turn a journal of approximately 30" diameter on one end of a crosshead-stalk guide assembly for a 4000 ton forging press.
we had planned to have this onsite machined, but now we have decided to remove it and send it...
any one out there still doing outside diameter roller burnishing??
i would like to find out if i a process we used years ago for railroad axle journals could be applied to large mill rolls i am now working with. i am also interested in internal (hole) sizing using a burnishing tool.
this seems...
i am working on a hydraulic manipulator that was built in germany probably 50-60 years ago. this is a 60 ton forge manipulator that uses water as the hydraulic medium at 100 bar accumulator pressure.
i am re-manufacturing some of the old valving and the print is in german, no problem in itself...
