BT ARBOR TOOL HOLDER

CNC tool holder CNC BT face milling holder,Face milling cutter  ,Cooperate with all kinds of the knife dish , is suitable for the gantry NC milling machine and general plane processing,Hole is beneficial to the water and strong vibration resistance,BT Face Milling Holder Can be customized Various non-standard length , can do dynamic blance test G6.3 G2.5

BT Face Milling Holder Material : 20CrMnTi;
BT Face Milling Holder Hardness : 58+/- 2 HRC;
7:24 taper tolerance less than AT3;
BT Face Milling Holder Carbon depth : more than 0.8mm;
Surface roughing : Ra less than 0.4u ;
Provide 2 kinds appearance :sand-blasting and electroless plating process;
Sub-zero treatment : All of the CNC chucks are processed long time Sub-zero treament (-180oC , more than 20 hours ) , Mke the residual austenite into martensite and precipitate  os nona-sized carbide particles , enhance chucks hardness, toughness durability, and reduce the residual internal stress, 
Thermal aging treatment can get rid of the residual interna stress in grinding process.
BT Face Milling Holder All the handle to do dynamic balance test, G6.3  G2.5.
