A Chuck Jaw is a replaceable clamping component used to hold workpieces in place during machining. It is typically mounted on a faceplate or chuck using T-slot bolts, and is suitable for various machine sizes and table configurations. Chuck jaws are widely applied in large vertical lathes, gantry milling machines, CNC machine tools, and grinders.
Depending on the machining requirements, users can choose between hard jaws and soft jaws. Soft jaws can be re-machined to match the contour of the workpiece, ensuring higher clamping accuracy and surface protection.
Chuck jaws are designed with attention to clamping force distribution, wear resistance, and ease of installation. Selecting the right jaws enhances workpiece stability, machining efficiency, and surface quality—making them an essential component of any workholding system.

A Synchronous Power Chuck, also known as a Wedge-Style Hydraulic Chuck, is a precision clamping device designed to control multiple jaws or clamping points simultaneously. It is commonly used in CNC lathes, automated machining systems, and applications requiring multi-directional precision clamping.
The key feature of this chuck is its synchronous jaw movement—all jaws open and close at the same time, maintaining excellent centering and concentricity during clamping. Internally, it uses a wedge mechanism or linkage system driven by hydraulic pressure. This transforms the linear motion of the piston into coordinated jaw movement, providing stable and powerful clamping performance.
By offering uniform clamping force distribution, it helps improve machining accuracy, stability, and operational efficiency. This makes the synchronous chuck ideal for holding round, disc-shaped, or shaft-type workpieces, as well as complex parts requiring multi-point clamping.

The Rotary Hydraulic Cylinder is the core driving component that operates hydraulic power chucks. By applying hydraulic pressure, the piston moves back and forth, transferring force to the internal mechanism of the chuck to enable precise clamping and releasing actions. It is typically mounted on the rear end of the machine spindle, and must offer quick response, high stability, and robust pressure resistance—especially in high-speed or heavy-cutting operations.
Hydraulic cylinders are available in different types depending on the chuck and machine setup:

1. Hollow Hydraulic Cylinder: Features a through-hole in the cylinder body, allowing bars, cables, air hoses, or pipes to pass through. This is ideal for bar feeding systems, multitasking machines, and signal/power transmission.

2. Solid Hydraulic Cylinder: Offers a compact, rigid structure with strong clamping force, suitable for setups that do not require internal passage.

Some cylinders are specifically designed with rotary and through-passage capabilities, making them ideal for applications that demand rotation, signal transmission, and automation integration—widely used in automated systems, heavy-duty machining equipment, and robotic platforms.
