The punching production has been seeking high speed and precision. The CNC roller wheel feeding machine manufactured by Shenzhen Xinghongfei Company is famous for its precision and reliability, which can realize the continuous and high speed feeding. It is in synchronization with various punching machine. The coordination of punching is completed by the photo-electric signal between the punching machine and CNC feeding machine, which destroys none part of the punching machine. Its movement track is completed by MITSUBISHI micro-computer processor and it has good flexibility. It can provide any feeding distance, closing stroke, relaxation stroke, jog adjustment, acceleration and deceleration according to the workpiece requirements. All these are processed in full digital. Roller column has circular motion with no seizure phenomenon. So it can reduce the fault rate. The combination of machine body and controller greatly save the space.
