The Front-Mounted Pneumatic Chuck II (KQ) is part of NBD Machinery’s power chuck and rotary cylinder line for CNC lathes and machining centers. Beijing Shuangfengli Technology (brand NBD Machinery) supplies this series factory-direct with short lead times, custom sizes and worldwide support.
Front-mounted pneumatic chuck Short cylinder front-lock screw connection form The chuck is easily installed, and its connection method follows industry standards, without having to change the original machine tool structure; the cylinder and chuck are integrated and designed, and one chuck can be mounted in front of and at the back of machine tools respectively to use at the same time. The chuck has a big bore diameter, and contains a one-way valve and has the function of reliable clamping; while the chuck is rotating, the sealing device is in the disengaged position, so it has 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. 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. The above data are the standard parameters, personalized customized solutions can be provided according to customer's requirement.
