SIEMPELKAMP | MACHINERY AND PLANTS
the Russian company placed an order with
Siempelkamp on a closed-die forging press
with a pressing force of 20,000 t permitting
the production of nickel-based
super-alloys.
By means of the press Electrostal will make
among others highly creep-resistant forgings
with dimensions of up to 1,200 mm of
length, 800 mm of width with a weight of
up to 800 kg. The parts are subject to increased
thermal loads and are applied in
aircraft turbines or power plants.
In the range of this order the new boring
and milling machine proves to be a strong
and precise allrounder: Several parts of
different sizes can be machined on PAMA
Speedram. Currently, a cylinder housing as
absolute king-size workpiece is under
progress with a gross weight of 225 t.
After machining the fi nished part will
