four-column hydraulic pressAccuracy refers to its own accuracy, which mainly includes the flatness of several surfaces of the die installation of an actuator. The relative position accuracy of each actuator relative to the flatness and non-perpendicularity of the work table (the datum plane of the four-column hydraulic press).
The accuracy of the four-column hydraulic press is also the same as the accuracy of any machine tool. It is determined by the accuracy requirements of the processed workpiece and the motion accuracy requirements of the pressing process. Low precision will reduce the precision of the parts, and even make the mold premature damage. Too high precision will increase the manufacturing cost. Therefore, it is very important for four-column hydraulic press manufacturers to reasonably formulate precision items and requirements.
Four-column hydraulic press main accuracy requirements:
1. Parallelism of worktable (0.05 in length of 1000mm)
2. Parallelism of the lower plane of the movable beam
3. Parallelism of movable beam to working surface (0.20)
4. Verticality of movable beam stroke to workbench (0.30)
