I. Introduction
The traditional steel bar straightening cutting machine uses hydraulic cutting. The steel bar is controlled by the hydraulic solenoid valve during the forward process, which is easy to block the material. Therefore, the speed is greatly limited during operation and the length is set by photoelectric Switch control, it takes a long time to manually adjust the steel bars of different lengths, which is time-consuming and labor-intensive. The VEC-VBR wheel cutting special drive contains the automatic wheel cutting machine control function. The driving Motor drives the wheel cutter to cut, and automatically changes the rotation of the tool with the length of the steel bar or the feeding speed, so that it maintains the steel bar at the moment of processing. The speed synchronization, the angle of the synchronization interval and the cutting length can be set by the touch screen. That is to say, the steel bar can truly maintain high speed and stable operation during the feeding process, thereby greatly improving production efficiency and reducing labor.

Wheel cutting servo system advantages:
1. The motion controller is written as software and integrated in the servo drive to reduce the failure rate of the motion controller to zero.
2, the drive contains high-performance 32-bit microprocessor and 125US dynamic high-speed computing loop, high dynamic response.
3, can be traced to the printing color punctuation, automatically correct the cutting length
4, VEC servo drive can drive permanent magnet synchronous motor, can also drive asynchronous motor, adaptability.
5. The whole system is simple, efficient and reliable, reducing production costs and maintenance costs.
Conclusion:
The system scheme is a mature control scheme, which has been used for many years in cross-cutting systems such as steel plates, corrugated papers, and card boards. Its stability is much higher than that of ordinary servo plus PLC, regardless of speed or accuracy. In the forefront of the same industry.
