1.Mechanical stop  and torsion bar  to maintain synchronization and high precision.
2.The machine uses Delem NC system,and imported linear transducer,pressure proportional valve and servo motor.
3.Ram stroke(Y) and backgauge(X,R,Z) are automatically controlled by computer.
4.Imported ball bearing lead screw and linear guide rail are used for rear stopper,to ensure the positioning precision of rear stopper,for processing precision of machine to be higher.
