Our piston cylinders with position feedback integrate LVDT or magnetic linear encoders (resolution ≤1 μm) for precise CNC machine control. The encoder is mounted internally or externally, providing real-time position data to the machine's CNC system. The cylinder barrel is honed to mirror finish (Ra ≤0.2μm) for smooth motion, while the piston uses a wear-resistant composite (PTFE + bronze) for low friction. With positioning accuracy ±0.02 mm and repeatability ±0.01 mm, they are used in CNC presses, laser cutting machines, and precision forming equipment. The feedback system supports standard interfaces (SSI, analog, Ethernet). Request encoder compatibility charts or visit [https://www.uranustj.com/] for CNC application notes.
