Core Functions

Precise Chain Drive

Hydraulic motors drive the tool chain to shift cutters rapidly and accurately to tool-change positions. Advanced electro-hydraulic control ensures steady chain rotation and high-precision positioning.

Secure Tool Clamping & Unclamping

During tool change, hydraulic cylinders paired with disc spring tensioning assemblies or direct hydraulic clamping structures reliably lock and quickly release tools on the spindle. The auxiliary gripper adopts jaw-type hydraulic auto-clamp/unclamp design to improve tool holding stability.

High-efficiency Manipulator Movement

Hydraulic actuators drive manipulator swing and 90° auxiliary tool sleeve rotation for smooth tool exchange; tool-to-tool swap cycle can be shortened to 3.75 seconds.

Optional Spindle Box Counterbalance

For vertical machining centers, hydraulic cylinders balance the spindle box to offset gravitational interference on Z-axis servo accuracy and deliver smoother Z-axis travel.

Key Advantages of Yangyu Chain Tool Magazine HPU

High Reliability & Long Service Life

Built-in pressure monitoring and interlock via pressure switches safeguard safe continuous operation for long service lifespan.

Energy Saving & High Efficiency

On-demand oil supply via variable displacement pumps or automatic unloading control cuts unnecessary power loss and heat generation.

Compact Layout & Low Noise

Optimized circuit layout and integrated components reduce overall footprint; premium hydraulic parts plus refined flow path design effectively suppress operating noise.

Strong Load Adaptability

High power density of hydraulic drive easily handles heavy-duty tool chains and secure clamping of large-weight cutting tools.
