1. Description
This product is a national patent product, independent intellectual property rights.
Chuck body itself is a cylinder, built-in piston, through the spindle tail control mechanism to achieve clamping and loosening action. This product is wedge-shaped three-jaw through hole with large diameter, especially suitable for the clamping of special-shaped objects. Sliding surfaces are hardened, precision ground and directly lubricated. The advantage of this product lies in its high rigid structure and high clamping accuracy. Its advantages are: 1. Compared with manual chuck, pneumatic chuck just click the button, instant automatic centering, clamping workpiece, and clamping force is stable and reliable, adjustable size, customers can choose comb tooth soft claw, hard claw, customized special-shaped claw, and can adjust the comb tooth position according to the size of the workpiece to process all kinds of parts; 2. Improve work efficiency, can realize one person to operate more than one CNC machine tools;
Products are suitable for gear processing, disk type, short shaft type of workpiece processing.
In addition to standard size collet, we also provide custom collet, suitable for CNC lathes, ordinary lathes and other equipment requiring rotary lathe improvement.
