This product is specially designed for laser tube cutting equipment. The product itself can be used as an independent rotating spindle, and a chuck in it can firmly clamp work-piece and rotate simultaneously. The quick clamping and loosening actions can be realized by side rotation and air intake. Disconnect the air source before operation. After the product base is fixed, to clamp and rotate the work-piece, it only needs to equip with a matching motor and connect it with the gear and meanwhile connect the
compressed air source (0.2-0.9Mpa).
The chuck can work in full stroke without additional adjustment of four jaws. It can clamp all applicable pipe fittings and improve production efficiency. Adopting a fully closed structure, the chuck has better stability and wear resistance. With cross roller bearing, it has longer service life, higher rotary accuracy and repeated positioning accuracy than traditional laser chuck, and greater clamping force than similar products in the market. In the case of low air pressure, a smaller clamping force can be obtained, thereby satisfying the need of processing thin-walled pipe fittings.
The product is widely used in special laser pipe cutters and other pipe processing machine systems.

Since the establishment of the company, now it has a number of patents( including innovation patents and utility model patents). The professional research and development team has been preparing to become a high and new tech enterprise in Jiangsu Province from the early stage of business operation. The products from Lingman Machinery are gradually spread to domestic and foreign laser cutting pipe market, and make a contribution to intelligent manufacturing in China.
Under the guidance of the industry's core values of Responsibility, Leadership, and Breakthrough', we continue to innovate in technology and strive to China's intelligent manufacturing technology leads the world's high quality development.






1. High transmission efficiency and synchronization accuracy.
2. When the external dimensions of the chuck are the same, the applicable size range of the processed pipe is larger, which can be effectively used to clamp thin pipes or fragile pipe fittings to prevent flattening, break through the limitation of round holes, and the clamping range is wider and more in line with the market demand.
3. The installation position of the reducer can be adjusted arbitrarily.
4. Reduce the difficulty of processing and manufacturing, which is conducive to mass production; Better dust-proof effect and stronger pollution resistance.
5. The product is widely used in pipe processing machine system such as special laser pipe cutting machine.
