Chuck jaw encyclopedic knowledge

Here I common knowledge about the basic knowledge of chuck jaws, I hope all of you some help.
Manual chuck: generally divided into the overall separation claw and claw. The claw is divided into positive claw and claw, claw type A separation claw and claw type C. Positive claw and claw is the three step, no screw hole. A type dog also called powerful claws, ladder shaped, 2 screw holes, C no claw ladder, 2 screw holes.
Such as domestic chuck: K11 (three jaw self centering chuck claw form as a whole)
K11-200A (three jaw self centering chuck is a powerful claw type)
K10 (two jaw self centering chuck type C claw form)
Such as the Taiwan SC (three jaw chuck ordinary type), PS (four claws ordinary type) for the whole jaw
SK (three claws strong type), PSK (four claws strong type) for A separation claw
TNT (Er Zhua) C type separation claw
Taiwan overall claw and A separation pawls are hardened and precision ground, hardness HRC55-60, while type C separation claw hardness is about HRC20-22 degrees.
Hydraulic chuck jaws (power chuck claw): generally divided into hydraulic claw hardware and hydraulic health claws, hydraulic claw hardware, hydraulic chuck is standard equipped hydraulic health claws.
Characteristics of oil raw claw: hardness of HRC-20/22 degrees, 60X1.5 angle gear, two screw holes and chuck T block combination, can be two times forming, such as L shape, arc and so on, is suitable for finishing.
The characteristics of hydraulic claw Hardware: after quenching and grinding, the hardness is up to HRC55-60, with a ladder. Suitable for heavy machining.
