HYDRAULIC STAMPING PRESSES

  These presses are designed to stamp large-sized part made of aluminium and titanium alloys and steels.
  Due to the high specific pressure rates developed in the dies, such presses may be used to make forgings of intricate shapes and large sizes with the minimum tobrances being maintained.
  NKMZ produces hydraulic presses up to 750 MN in force.
    Advantages:
  • high accuracy of stampings is assured by timing system, which provides the parallelism between the table and the walking beam;
  • maximum liquid pressure in working cylinders is assured by multiplying gears;
  • automatic system of technological control of beam travel and speed, liquid pressure in cylinders, technological capacity eccentricity and tension in basic parts;
  • availability of pullers for stamped parts removal.
