Sub-zero treatment:
All of the CNC chucks are processed long time
sub-zero treatment(一180℃,mare than 20 hours) Make the residual austenite into martensite and precipitate of nano-sized carbide particLes,enhance chucks hardness.
toughness durability,and reduce the residual internal stress.
Thermal aging treatment:
Long time thermal aging treatment can get rid of the residual
interna stress in grinding process.
