Tormach Tooling System: Maximizing Performance and Preventing Collet Slip

A video overview on how to maintain, improve and maximize the Tormach TTS tooling system in order to prevent collet slip. Includes information on cleaning & degreasing as well as where to lubricate the collet, drawbar and more.

Good vid i also posted on the zone recently. I was having massive pullout issues. When the anti sieze fixed all my problems perfectly!.

I did notice you pulled a screw out when removing your pdb.... Do i have something installed wrong? I can remove mine just buy flipping out the bolt on the right that holdes it in posiiton and i can just lift it off of that alignthment shaft. Just making sure i didnt miss a step when installing it.

@S2GamesJesse Thanks for pointing that out. Yes, you are absolutely correct - no need to remove that screw. Thanks, too, for your cnczone posts on this issue -that was my inspiration to investigate on my machine!

Good info. Where are you at with the CNC Plasma Table?

@zippy308 Working on it.. Was away last week for work. Need to square up the gantry then mount it on the water table, then dig into the wiring & electronics

I undedrstand there is a BT30 spindle for the Tormach. With that said, Don't use cheaply made R8 collets. I had problems with using cheap R8 Collets in my Bridgeport mills. I perfer the Royal brand or Lyndex R8 collets in my standard manual machines. I have no idea the quality of the Tormach collets. Recently though I have seen a older Tormach mill retrofitted with a FANUC Oi-MC control. These are really neat fairly affordable controls that are pretty easy to set up and install.

I'd blue the collet up and load/unload the spindle several times to get a good idea of how much of that taper is actually doing work. If all of the work is being done by the end of the taper, I'd call Tormach and ask them to rethink their design.

On the lubrication, I agree with all of your application points, but I would wipe about 80/90% of the anti-seize off of the taper. With that much it's definitely going to get into your shank as heat develops on the taper. A little goes a long way.

[anonymic79]

It seems like your collets aren't meeting the taper properly inside the spindle. My experience with collets on turning centers and mills in the past has been that the collet seats with even pressure along the entire length of the taper when loaded with the appropriate diameter tooling or part. Pinching only on the far end of the taper may be leaving the back of the shank loose and unsupported.
