YITCH Air‑Hydraulic Tool Cylinder | Core Component for Automatic Tool Change in CNC Machining Centers

In precision CNC equipment such as machining centers, CNC milling machines and tapping centers, the tool cylinder is a critical air‑hydraulic component for spindle automatic tool release, clamping and tool change. It directly determines machine tool efficiency, stability and processing accuracy.

Developed and manufactured by Shanghai Aohu Automation, the YITCH tool cylinder series adopts mature air‑hydraulic boosting technology, providing high‑stability and long‑life solutions for tool clamping and automatic tool change for various CNC spindles.

1. Application & Working Principle

Main Applications

• Realize fast tool release and precise clamping with stable, shock‑free movement

• Cooperate with tool magazines for fully automatic tool change, suitable for unmanned production lines

• Prevent tool shaking and spindle damage, maintain positioning accuracy and improve finished product rate

Working Principle

YITCH tool cylinders adopt air‑hydraulic boosting structure. Driven by compressed air, hydraulic pressure amplifies output force, delivering small size, large thrust and fast response. Smooth clamping and releasing with low vibration and low wear, ideal for high‑speed and high‑precision machining.

2. Three Main Product Series

1. Belt‑Drive Spindle Tool Cylinder – Micro‑Switch Series

Designed for belt‑drive spindles. Micro‑switches provide accurate signal feedback with stable positioning, perfect for precision machining.

2. Belt‑Drive Spindle Tool Cylinder – Magnetic Induction Series

Non‑contact magnetic induction, dust‑proof and anti‑interference, longer service life, easy installation and reliable long‑term operation.

3. Direct‑Drive Spindle Tool Cylinder

Customized for high‑speed direct‑drive spindles. Compact and rigid structure, withstands frequent tool changes, reduces vibration loss and protects spindle accuracy.

All series come with dimension drawings, installation diagrams and air‑hydraulic circuit drawings for easy integration.

3. Five Key Advantages

1. Integrated Cylinder Body & Patented Sealing

Leak‑proof structure with excellent sealing performance, lower maintenance cost and longer service life.

2. Precise Guidance & Stable Boosting Output
