<p>The hydraulic press comprises a fixed apron (4) and a moving apron (5) and incorporates, inside the fixed apron, pressure means (2) to compensate the deformations occuring during the operation of the press. A processing central unit (7) receives the information of measuring means (3) of the deformation, which are located inside the fixed and moving aprons and/or between the tool holder and the tools, and controls the pressure means (2) so that during the working phase, optionally extended up to the time of inverting the working motion, both tools are exactly parallel. The advantages are such that a very accurate work is provided, without requiring the skills of the operator.</p> |
