200 250 400mm Three Jaws Self-centering Lathe Chucks for CNC Machine
1. Description
Three claw self-centering chuck is mainly used in metal machine tools, can be self-centered clamping or support round, triangle or hexagon and other shapes of the outer surface or inner surface of the work-piece, a variety of mechanical processing, clamping force adjustable, centering accuracy is high, can meet the precision requirements of ordinary machine tools.
The standard of three-jaw self-centering chuck is an important basis for product design, manufacture and acceptance, and also provides reference for supporting the host.
Basic structure and working principle: three jaw self-centering chuck using three screws, through the disc body stop on the end face of the screw hole, the chuck is fastened on the machine flange. Insert the wrench into any square hole in the gear. When turning the wrench, the pinion drives the disk wire to rotate, and drives the three clamping claws to advance or disperse at the same time through the rotation of the screw thread on the end face of the disk wire.
Here are some features of the self-centering chucks: Short cylinder center mounting; model K11 chucks are provided with one-piece jaws (which includes a set of internal jaws and a set of external jaws); the raw material of chuck is steel; all kinds of soft jaws are also provided.
