Y1, Y2 can be programmed separately, can work in the partial load state, but also cone-shaped bending;bottom dead center has a pressure time, programmable, to ensure that the accuracy of different parts;has a slow return control function, the operator can better control the workpiece; imported GIVIlinear optical reader,guiding system,positioning system and hydraulic balancing system with high precision, which all can permit the processing work piece of full length or with eccentric.Special treatment about the cylinder--rough treatment--hardening--inner grinding--inner Float boring, make the inner side of the cylinder with high precision andwearresistantPipe fitting and seals of hydraulic system is SKF brand which imported from Austria, good quality and high performanceHydraulic connector are imported from Europe and America;,with good qualityOverload overflow protection is outfitted to hydraulic system, which can assure no leakage.Oil level can be read or seen directlyBeing able to work continuously under rated load and hydraulic system shall have no any leakage, stable working, high precision positioning5,Back gaugeGood for work piece needing multiple steps of bending with high precision requirementThe speed of backgauge is fastest,andhigh precision.X,Raxis of back gauge is moved with ball screw, guided by linear guide, and driven by digital AC servo-motor.(Optional) Z1, Z2 axis two blocks move left and right along the linear guide automatically, easy to operate, high precision;Back gauge beam is tank structure,with good enough mechanical strength and rigidity Particular finger-stop design, enlarge the range of back gauge.6,Electrical systemElectrical components are imported or from Sino-foreign joint Venture, in accordance with international standards, reliable safety, long life, good anti-interference abilityEquip with movable food panel,convenient operating,emergency stop7,WILA Mechanical Crowning CompensationWILLA mechanical crowning system integrated in the table,the high-precision crowning system is automatic adjustable via CNC controller.Point-focal adjustment options with precise basic setting for accurate bending angels 8. CNC control system standard is DELEM DA58(2D graphic display and 2D programming)optional: DELEM 66T .9. Others:Standard have step-adjusted front support, with a rotating function, to avoid the workpiece when bending (see below)Foot switch, the bottom plate equipped with wheel, move more convenient10.
