Secure & Reliable Slot Design

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

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.
