1.Dynamic balance level: ≤G1;
2.High precision: Run-out precision of cutter handle≤0.002 mm;
3.There is high axial and radial resetting accuracy; theresetting accuracy is ≤0.002 mm;
4.There is high dynamic and static rigidity andstability, high axial and radial accuracy; it can guarantee the productaccuracy during high speed machining;
5.HSK cutter handle has hollow short-taper shankstructure. Compared with BT cutter handle, HSK cutter handle has short length,light weight and faster cutter changing speed. It is particularly suitable tohigh speed machining;
6.Compared with traditional cutter handle with chuck,thermal shrinkage cutter handle has the following advantages:
a.Compact structure, high rigidity: Direct connection isperformed between cutter handle inner hole and cutter, and there is no carrier.
b.Large transmission torque: The torque output that is 2times of that of cutter handle with ER chuck (or more) can be realized.
c.Wide adaptability and good machined surface quality:It is applicable to rough machining and finish machining, and the machinedsurface quality is very good.
d.High clamping accuracy: Generally, the clampingaccuracy of cutter handle with chuck is ≤0.005 mm (at 4D position), and therun-out precision for cutter clamping of thermal shrinkage cutter handle is ≤0.002 mm (at 4D position).
(1)The handle accuracy of cutter shall be H6.
(2)The cutter shall be made from tungsten steel, hardalloy.
