Short cylinder rear-lock screw connection form

The chuck is easy to install, with a connection method that adheres to industry standards, eliminating the need to modify the original machine tool structure. The cylinder and chuck are integrated in design, allowing a single chuck to be mounted both at the front and rear of the machine tool for simultaneous use.

The chuck features a large bore diameter, incorporates a one-way valve, and provides reliable clamping; moreover, when the chuck is rotating, the sealing device is disengaged, thereby ensuring a long service life.

Working principle: the clamping power source of the chuck is compressed air; when compressed air flows into the one-way valve through a distributing ring and then into the chuck cylinder, thus to drive the piston, so that the jaw clips a workpiece tightly; then, the reversing valve is powered off, and the air pressure within the cylinder is sealed by the one-way valve. The sealing device of the distributing ring is released, not to contact the chuck body, and the equipment can be started for normal work at this time.

Note: Since the chuck is ventilated in both the clamping and releasing states, and the special sealing element on the distribution ring tightly clamps the outer circumference of the chuck body, the machine tool spindle must be stopped while the chuck is clamping or releasing the workpiece.

With two functions of clamping and holding.

Short cylinder front-lock screw connection form

The chuck is easy to install, with a connection method that complies with industry standards, eliminating the need to modify the original machine tool structure; the cylinder and chuck are integrally designed, allowing a single chuck to be mounted on both the front and rear sides of machine tools for simultaneous use.

The chuck features a large bore diameter, incorporates a one-way valve, and provides reliable clamping; moreover, when the chuck is rotating, the sealing device is disengaged, thereby ensuring a long service life.

Working principle: the clamping power source of the chuck is compressed air; when compressed air flows into the one-way valve through a distributing ring and then into the chuck cylinder, thus to drive the piston, so that the jaw clips a workpiece tightly; then, the reversing valve is powered off, and the air pressure within the cylinder is sealed by the one-way valve. The sealing device of the distributing ring is released, not to contact the chuck body, and the equipment can be started for normal work at this time.

Note: Because the chuck is ventilated in the clamping and released state, and the special sealing element on the distributing ring clamps the excircle of the chuck body tightly, so the machine tool spindle should stop rotating while the chuck is clamping and releasing the workpiece.

Three-claw long stroke, is suitable for parts with large yield requirements.

The 10° cone can be clamped when the workpiece is secured and retracted. The claw can swing freely by 5° from left to right and provides strong clamping force (as shown in the figure);

A special chuck with center compensation is also available;

Easy conversion between inner diameter clamping and outer diameter clamping;

The repeat positioning accuracy is up to 0.03 mm.

Two Tip Processing Methods for Shaft Parts

Clamping is convenient, relying on center positioning hole for fast clamping

Workpiece centering can be achieved using a fixed center, ensuring precision during secondary machining.

Used for tow top ways for machining axis parts

Clamping is convenient, relying on orientation of center hole for rapid clamping

The workpiece can be aligned using the reference diameter of the fixed center, while the clamping jaw only provides driving torque and retracts to a fixed reference point.

VL series wedge-type medium-solid vertical chuck.

Chip-proof and waterproof design.

Four or six claws can be designed according to the user's requirements.

Double-action with ejector pin can be customized.

Chip-proof and waterproof design.

Four or six claws can be designed according to the user's requirements.

Used for the automatic efficient process of shaft parts and flange parts of right Angle, 45 ℃, 45 ℃, 60 ℃ , 90 ℃ , 120 ℃ and 180 ℃ .

Processing of mass parts with high indexable precision, such as valve body, cross shaft, pipe fittings(elbow and tee).

The indexing mechanism is hydraulic (ensuring strong clamping and being adjustable).

One clamping to complete the shaft processing

Rough machining employs a compensating claw for clamping.

Upon completion of machining, retract the claw and use the end-face driver to finish processing all parts.

Positioning by central hole in the axial direction

A fixed tip can guarantee the highest concentricity.

The drive pin is actuated by piston 2 of the double-piston cylinder, applying jacking force to the end face of the workpiece (piston 1 is used for chuck actuation).

End-face drive clamping/the loose position can be monitored through a proximity switch/LPS

The highest accuracy – without adjustment

The tip can be customized according to the size of the work piece during ordering.

Back-pull clamping, applicable to processing of parts with higher requirements for verticality and parallelism, with wide clamping range.

It can be used in different ranges by replacing the 3 claws.

Use connecting flange
