1. Precision mechanical design:

The precise positioning of a twin-shaft cylinder begins with its precise mechanical design. During the design process, high-quality guide rails, linear axes, and precision sliders are selected to ensure smooth and stable cylinder movement. Factors such as friction, vibration, and mechanical looseness can cause motion instability, so designers need to carefully consider these factors and take appropriate compensation and stabilization measures.

2. High resolution sensor:

One of the keys to achieving precise positioning is the use of high-resolution position sensors. Sensors such as grating scales and encoders can provide real-time position feedback, comparing the actual position with a preset target position. This real-time feedback allows the control system to correct for any misalignment and make fine adjustments to the position of the cylinders, resulting in precise positioning.

3. Closed-loop control system:

In the actual movement process, errors are inevitable. In order to compensate for these errors, dual-axis rod cylinders usually use a closed-loop control system. The system continuously compares the actual position reported by the sensor with the expected position and adjusts the movement of the cylinder accordingly. This real-time feedback control corrects any positional deviations during motion to ensure precise positioning.

4. High precision control algorithm:

The control algorithm is the core to achieve precise positioning. Advanced control algorithms, such as PID control, fuzzy control, etc., can calculate and adjust the speed and acceleration of the cylinder in real time according to the position information fed back by the sensor. This helps ensure that the cylinder stops smoothly when it reaches its target position, reducing vibration and positional deviation.

5. Compensation mechanism:

The impact of environmental factors on positioning accuracy cannot be ignored. For example, temperature changes can cause the material to expand or contract, affecting the precise positioning of the cylinder. By implementing compensation mechanisms such as temperature compensation and slack compensation, the system is able to correct for these factors and maintain positioning accuracy.

6. Multi-axis collaborative control:

For applications that require coordinated motion in multiple axes, dual-axis rod cylinders can achieve greater precision through multi-axis coordinated control. The multi-axis cooperative control system can coordinate the movement of each axis to keep them synchronized at a specific position and time, so as to achieve higher positioning accuracy.

7. High performance controller:

To achieve precise positioning, the performance of the controller is critical. A high-performance controller can handle complex control algorithms and real-time feedback to ensure that the cylinder can move according to the expected trajectory.

LTCXSM series double shaft rod cylinder
A Double Shaft Rod Cylinder is a type of hydraulic cylinder that features two opposing ends and a single piston. These two ends do reciprocal work. Both of them move with equal force, stroke length, and speed. These types of cylinders, which feature push and pull force from both ends. They are also available in various bore sizes. To ensure their longevity, the cylinders are designed for high-speed applications.
