Sealed TF-25 or 0161 collets for hp coolant

[ET.SC.ENG.]

Hello,


I'm running a chip blaster unit on a DMG Sprint 20, and I'm grtting too much coolant going thru the spindle, I contacted S&M Hardinge and Keb about sealed TF25 collets but no luck, I have tried sealing the collets myself but the end up sticking at unclamp, has anyone had this problem? any solutions?

In the past I have sealed collets by making a fixture that matches the collet sleeve and cap.I then tighten the collet onto a gage pin,fill the slots with silicone and let set overnight.Usually any oil resistant rtv type will work.
good luck

Have you resolved this issue yet? We have 2 DMG/SPRINT 20 machines and are experiencing the same issues.
I have started using " SCHAUBLIN " collets and so far they are proving out to be very successful.
What have you done differently since you posted this?
