MTA Morse Taper Arbor

Comprehensive
features of CNC Chucks
Materia1:20CrMnTi;
Hardness:58士2HRC;
7:24 Tapper tolerance≤AT3;
Carbon depth>0.8;
Surface roughness:Ra<0.4u;
Provide 2 kinds appearance;Sand一blasting and Electroless plating process;
Sub-zero treatment:
All of the CNC chucks are processed long time
sub-zero treatment(-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.

1.Laser marking exact optical marking of the unbalance positions on the tool

2.Presetting Measuring system with high resolution camera and digital photo processing
