Integrex 2nd Spindle - Tailstock

I have several Integrex 100st 2009 - 2012 with Matrix control. I'm looking for a way to use a Tailstock body mounted in the chuck of my 2nd spindle.

Background: I have tried spring loaded tailstocks mounted inside the 2nd spindle chuck but they don't have the dynamic capability and slip. I have tried mounting a Tailstock on my lower turret and have had the same result.

Question: do you know of a way to mount a Tailstock body inside a 2nd spindle chuck and apply dynamic pressure with the 2nd spindle while engaged.

Prior to my Integrex days I ran Nakamura machines with 2nd spindles and we used a "soft push" function to create the dynamics needed.

Any help would be greatly appreciated.

Thanks,

Hi we use 2nd spindle all the time.

We don't use spring centres! Just move w axis in to job and watch the load meter, load it to 25-50%, works fine

I'm not sure I follow you. Are you pushing the W-Axis into the part until the 2nd spindle load reaches 25-50%?
