New Hi-Power Milling Chuck


New Hi-Power Milling Chucks achieves powerful clamping for heavy cutting. Fine slots and needle bearings assure powerful an precise clamping. Even though a milling chuck is for heavy cutting, the New Hi-Power Milling Chuck keeps runout accuracy of .0004" T.I.R. at 4xD

Powerful, Heavy Duty End Milling

Powerful, Heavy Duty End Milling

  • Powerful clamping for heavy cutting
     
  • The thick wall on a clamping part (e.g. 10mm thick for ø32) prevents chattering
     
  • Coolant-through hole


  • Keeps runout accuracy of .0004" T.I.R. at 4xD
     
  • CV40/50 clamping range ø.750" - 1.500"
     
  • BT30/BT40/BT50 clamping range ø.750" - 1.250"




A Variety of New Hi-Power Milling Chuck




CAT Shank Series
CV40, CV50


Clamping Range Dia.: .750"-1.500"
The thick wall on a clamping part (e.g. 10mm thick for ΓΈ32) prevents chattering.



BT Shank Series
BT30, BT40, BT50


Clamping Range Dia.: .750"-1.250"
Supports heavy and finish end milling with high power and precision



Secure & Reliable Slot Design


Fine and narrow slots make the clamping part deform properly. The clamping part evenly clamps a cutting tool's shank for heavy cutting. The slots also eliminate the oil that spoils clamping torque.





High Concentricity achieves low T.I.R.


Even though a milling chuck is for heavy cutting, the New Hi-Power Milling Chuck keeps runout accuracy of .0004" T.I.R. at 4xD.


Clamping Torque of New Hi-Power Milling Chuck (HMC1.250)


High Clamping Torque!

Tightening torque is magnified by tightening the nut with an original design of a roller bearing as in the figure shown below. When a roller bearing smoothly brings the nut downwards, a wall on a clamping part of the chuck elastically deforms and high clamping force is achieved on a cutting tool's shank. Furthermore, the wall is designed to be thick enough to prevent chattering.

 

Plug Screw for Flange Through Coolant

 

This Plug Screw A (option) prevents coolant leakage through retention knobs.

Bores on Form B are sealed with Plug Screw B.

  • Remove Plug Screws B (2 pcs.) from end face of flange.
  • Failure to use the Plug Screw "A" or other sealing method may result in coolant contamination of the spindle and lead to premature failure or accidents.
