Balancing the Pin Box: A Revolutionary Approach to High-Precision CNC Boring
In the realm of CNC machining, precision and reliability are of paramount importance. The Gimax200 CNC Floor Boring, jointly designed and produced by our company and the forest line, France, is a testament to this commitment to excellence. At the heart of this innovative machine lies the pin box, a critical component that requires meticulous balancing to ensure flawless performance. In this blog post, we’ll delve into the intricacies of the pin box balancing system, revealing a cutting-edge solution that sets new standards in the world of CNC boring.
The Pin Box Balancing System: A Complex Dance of Metal and Oil
The pin box is a statically guided rail system that features a hydraulic balance to counterbalance the weight of the pin box itself. This ingenious design enables the system to compensate for changes in the center of gravity caused by the movement of the pillow and loading or unloading of accessories. The process is illustrated in Figure 1.

The system consists of a pair of oil cylinders, 6 and 7, connected to a moving pulley. The front wire rope is directly attached to the pin box, while the rear wire rope is coupled to the spindle box through the oil cylinder. Two servo valves, 1 and 2, control the oil cylinders through hydraulic control, allowing for precise adjustment of the flow and pressure.
The Role of Servo Valves 1 and 2: Balancing the Forces
The servo valves 1 and 2 are equipped with position sensors and pressure sensors, enabling quick and precise control of the flow and pressure. Their work process is illustrated in Figure 2.

When switch 1 is activated, flow control is achieved through comparison of the UL1 voltage signal with the UQS control voltage signal, controlling the movement of the valve core. When switch 3 is activated, pressure control is achieved through comparison of the UP1 pressure signal with the UP2 control voltage signal.
The Gimax200 Advantage: Redesigned Servo Valve System
The Gimax200 boasts a redesigned servo valve system that utilizes the Y-axis movement compensation method to address the issue of deformation caused by the weight of the boring bar. This innovative approach ensures that the boring bar remains precisely controlled and accurate, resulting in improved overall performance.
Conclusion
The Gimax200 CNC Floor Boring’s pin box balancing system is a testament to the power of innovation and precision engineering. By combining advanced technology with meticulous design, our company and the forest line, France, have created a machine that sets new standards in the world of CNC boring. Discover the secrets behind this remarkable machine and experience the benefits of advanced precision machining with the Gimax200.
