ZYG Series: The Heart of High-Speed CNC Tool Changing


The ZYG series tool change cylinder is a critical pneumatic actuator designed specifically for Automatic Tool Changer (ATC) systems in CNC machining centers. Its primary function is to provide the high-axial force required to release the tool holder from the spindle taper (unclamping). Engineered for speed, precision, and durability, the ZYG series ensures seamless tool transitions in high-productivity environments.


Key Technical Features & Engineering Highlights

  • High-Force Unclamping: Utilizes a multi-stage or high-pressure pneumatic design to generate the massive force needed to overcome spindle spring tension, ensuring reliable release of BT30, BT40, and BT50 tools.

  • Integrated Buffer Technology: Features a built-in "anti-jump" buffering mechanism. This prevents the spindle from axial jumping during the tool release process, effectively protecting high-precision spindle bearings from impact damage.

  • Rapid Response & Cycle Time: Optimized internal air passages allow for lightning-fast inflation and exhaust, minimizing non-cutting time during tool change cycles.

  • Robust & Stable Construction: Built with a hard-anodized aluminum alloy cylinder body and high-strength seals to withstand millions of tool change cycles in harsh machining conditions.

  • Status Monitoring: Equipped with slots for proximity sensors to provide real-time feedback for "Tool Unclamped" and "Piston Retracted" positions, ensuring system safety.
