Claim:
Press for producing dimensionally stable pressed parts from powdered material, with a press frame, a die holding plate, at least one upper punch holding plate, at least one lower punch holding plate, adjusting drives for the upper punch and lower punch holding plate and/or die holding plate, a vertical guide in the press frame for guiding at least the upper and lower punch holding plate and supporting a measuring rule for measuring the position of the upper punch holding plate, the lower punch holding plate and/or the die holding plate, wherein the vertical guide is uncoupled from the press frame, such that a relative movement between the press frame and the vertical guide is possible, whereby alterations to the length of the press frame caused by heat and press forces produce no alterations to the length of the vertical guide, and the measuring rule is attached to the vertical guide at a thermal fixed reference plane which is the centre of the measuring rule, and wherein a plurality of measurement slides cooperating with the holding plates are guided on the measuring rule.
