GK11 Series 3 Jaw Steel Material Self Centering Manual Chuck Lathe
Chuck
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
