I forgot to respond to the heart of your question, sorry! I've tried to shortcut the process for checking the Y and Z axes, but it's not as reliable.

Of course, the X-axis can be fully checked...

It's definitely not the easiest thing to keep track of! The parallel distribution system is a bit of an Achilles heel on all of the series 3 machines. I've spent many hours sweating over it, so much...

Hi All,

Just had the chance to test compressed air through a loc-line style hose on a Tormach 770 during fly cutting on HDPE and 6061. However, I'm not sure as to the best way to position the...

Hi All,

What do you all use for repairing dents and high spots on your CNC machine tables? Also, where could you buy one?

I've got a Tormach 770, and have bought two grits of 8" Diasharp...

On my shop's 770, I see a bit under 0.0002" TIR at the spindle taper, BUT the TTS system ER-20's give me anywhere from 0.0003" to 0.0025" TIR at the cutting plane, depending on the assembly and...

Fantastic responses all, thanks for the insights!

I completely forgot to mention the oil I'm running: Tormach's re-branded 68 way oil. Not sure if this is actually Perlube, or Smitty's Supply. The...

Sorry to hijack this thread, but you described a situation I think I'm going through twocik. Gib adjustments aren't behaving as expected, and I've seen some very conspicuous scarring pop up after...

Hi All,

I've got a 770 with a manual oiler, that only sees action in spurts. I.E., there will be 2 weeks of daily use, and 2 weeks of downtime, due to the R&D environment I'm in.

When leaving...

I hate to change the general tune here, but my experience with Tormach CS has been mixed. It went from supportive and cordial (responding to every single point I brought up via email), to techs...

Yes, I agree, the collet shouldn't have moved much at all with respect to the tool holder's taper. You bring up a great point, can't forget that there's always going to be some deformation going on...

Hi All,

So, my Tormach Setup saga continues (it's been over a year now, and only 2 parts have been made... for various reasons, but mostly because Tormach designed things just didn't ever fit...

Been waiting for 2+ weeks on an order with 4 parts to ship... pretty sad!

According to a local article from last year, they were already facing space crunches in their new 2013-built location. Not...

Hi All,

A big thank you to everyone who responded to my original post! Plus, this has turned into an interesting discussion.

I wanted to get back with the results of a few test sooner, but...

Ian,

Great stuff. I was thinking along the same lines with regards to the twisting. Definitely a result of uneven torquing somehow, my initial guess was uneven burr formation on the collet 30 deg....

I have a bad R8 "TTS" length collet in the 770 right now.... suspected it had a grinding error. Going to try stoning the interior edges for sure now. Had a nice big bit of swarf stuck in one of the...

I can't imagine the stock wrench could allow a seriously hard pull to put more than 40 lb. ft. into the nut/toolholder assembly, unless you've been doing some serious bulking up. That should've been...

Bahahaha :D. And yeah, wish I had just used the supplied wrenches and gone that low-torque route first (but instead, I read and researched too much for my own good). This whole fiasco was due to my...

Personally, I don't have any experience with the 38mm facemill.
I use my Superfly mostly for ultra-fine mirror-finish finishing cuts in Al and Cu on the 770. I didn't check the videos posted here,...

Hi All,

Sorry if this is slightly Off Topic (this is all related back to my Tormach 770 setup adventure, I can assure you), but I was really hoping someone here has seen this in their own TTS...
