3) On the bottom surface of upper gantry beam, hydraulic jacks are installed, for pressing the workpiece firmly;

4) The array of hydraulic drive jacks pressing the steel plates firmly in the Wuxi JACK Large Size Edge Milling Machine: (Fig.2)

2. Installation and Levelness of Worktable in SXBJ-12 Large Size Steel Plate Edge Milling Machine:

1) For pulling the workpiece out from processing zone of the Edge Milling Machine, shall make the indentations for freely moving of the hydraulic push devices through it;

2) Wherein, indentations shall not be placed directly under workpiece clamping hydraulic jacks;

3) For stable fixation of the mechanical bed of the machine on a foundation, and to avoid deformation (deflection) of working table surface, installation and height adjustment shall be made with use of release forced adjusting bolts according to the scheme, similar to showed in sketch:

4) Design sketch on Adjusting Bolts for installing and height modulation of worktable in the Metal Plate Edge Milling Machine: (Fig.3)

3. Milling Head 3 Axis Movement in the SXBJ-12 Large Size Metal Plate Edge Milling Machine:

1) Milling head should have ability to install mill with conic shank end. The delivery set of the large size machine should include the pull stud for mill fixing;
