    5.Features

    ◆The frame of combined structure has been heated processed and highly frequently vibrated, that guarantees the whole precision, rigidity, excellent torsion and stability of the machine. The thick working bed plate and ram give the assembly high rigidity. The linear and angle of the finished plate are the same.

     

    ◆Germany digital loop hydraulic system (electric-hydraulic proportional servo synchronous control system), position control system, uses the linear encoder to check the anachronous error of the ram and correct it by using CNC electric-hydraulic servo valve. Keeps the parallelism between the ram and working bed. Ram synchronous accuracy: ≤±0.02mm

    ◆Y1-Y2 axes -Spain Fagor precise linear encoder  installed on the ram’s right and left, are used in measuring the distance between the ram and working bed. The linear encoders are installed on both side plates of machine. The CNC system calculates the output servo valve control signal (S1-S2) as soon as receiving the positioning feedback of linear encoders. Ram positioning accuracy: ≤±0.02mm, ram repeated positioning accuracy: ≤±0.01mm

    ◆X axis is the back gauge control axis. The back gauge adopts the high pressure torsion servo motor, accurate ball screw and linear guide, which makes the positioning accuracy of the X axis≤±0.1mm. Both back gauges are synchronized during working which ensures the work piece’s accuracy as well.

     

    ◆Low worktable has an automatic crowning compensation unit, compensation amount is automatically set up by CNC system, with guarantee a same bending angle on full length.The special desgin of worktable to effectively reduce the bending deflection of die.
