1.Steel-welded frame could make sure high strength,high rigidity and high accuracy. 2.Using of machanical forced synchor system,both sides of sliders move in parallel by synchro axis. 3.Deflection compensation unit is installed in the upper mold,Upper mold clamping device is an option. 4.When NC press brake,X-axis backgauge is driven by servo motor,adoapted ball-screw and linear guide way. 5.When NC press brake,ram stroke are controled by servo moto,it could make sure higher positioning accuracy.
