THE STRUCTURE OF THE MACHINEWelded steel plate, the frame consists of right and left wall boards, working table, oil box, groove steel etc. Work table consist of 3 plates. The stress of the parts has been eliminated by vibration. The machine enjoys high accuracy and high strength and good rigidity.HYDRAULIC SYSTEMIt is a complete electrolyte servo synchro CNC controlled press brake.It adopts the most world advanced electrolyte servo system.The hydralic force is very reasonabley designed and also easy for installation.It minimizes the quantities of oil passages and connectings in which way the reliability and safety can be guaranteed.MECHANICAL SYSTEM(1) It adopts the electrolyte synchro control system whose acuracy is very high.(2) It adopts the working table compensation structure in which way the accuracy can be improved.(3)Ball screw on the backgauge, moving without gap enhancing the accuracy of positioning.SYNCHRO CONTROL SYSTEMThis machine adopts the electrolyte servo system whose accuracy is very high.Two light rulers (Y1-Y2) have been installed at the two sides of the machine to measure the exact distances between the slide two ends and the working table. The rulers are connected with the working table. In this way, the wallboard deformation will not affect the slide positioning accuracy.The position data will be delivered to the CNC system and then it can check out the servo valve control signal (S2-S2).THE DEVIATION RESISTANCE ABILITY OF THE MACHINEThe elctrolyte servo system of this machine is an inner closing ring control system.It can check out the synchro discrepancies of the slide by the movement of the light ruler.And the electrolyte servo valve can correct the slide discrepancies. This can make the slide always be parallel to the working table.
