CUSTOMER & TEST PROFILE

CIRCUMSTANCES:
A Sheridan-Gray (a Division of Erie Press Systems), 1500
Aluminum Stretch Press used to stretch and shape 0.061”
to 0.091” thickness aluminum, 85” wide by 290” long for
the C-17 aircraft skins. The skins were galling and marring
material surfaces and the die surfaces during the stretching
operation. All die lubricants used to that time were inade-
quate to cure the problem. There are two (2) jaws on the
press, each jaw exerting 75,000 tons of pressure. Under such
high pressure, frequent die-lubricant failure occurs. Material
costs are very high, and man-hours spent reworking, replac-
ing, and reshaping the materials are extremely costly.
This machine is a similar machine to the one McDonnell Douglas has
