1. Description
 

GK11 series of self centering chucks are mase of steel, with better rigidity,durability and higher speed, which meet the needs of high-speed cutting. Three-jaw self-centering chucks are mostly used in metal machine tools. Self-centering clamping or clamping of external and internal surface workpieces such as round, triangular or hexagonal for various machining and clamping. The tightening force is adjustable and the centering precision is high, which can meet the precision requirements of ordinary machine tools.

The three claws are centered at the same time, and the clamping accuracy is stable. The body material is cast iron. Application scenarios: Mainly used in CNC lathes, ordinary lathes and other machine tools to clamp workpieces

Basic structure and working principle: The three-jaw self-centering chuck adopts three screws to fix the chuck on the flange of the machine tool through the screw holes on the end face of the disc body. Insert a wrench into any square hole in the gear. When the wrench is turned, the pinion drives the coil to rotate. The rotation of the thread at the end of the coil moves the three jaws forward or apart simultaneously.

The three-jaw self centering chuck is driven by a small bevel gear and a large bevel gear. There is an Archimedes spiral groove on the back of the large bevel gear, which meshes with 3 claws. Therefore, turning the small bevel gear with a wrench can make the three jaws move radially at the same time, realizing automatic centering and clamping

Features:
1. Short cylinder center mount.
2. K11 type chuck has one-piece jaws (including a set of inner jaws and a set of outer jaws).
3. The raw material of the chuck is steel.
4. Various soft jaws are also available.
