My machine is doing this.

I tightened my spindle bearings and it helped but not fixed it.

Thinking to tighten the Y axis gib next. It's only noticeable during straight line X-only cuts while...

Pics?

Interesting comments in this thread. I can fully acknowledge the Tormach is not a professional grade machine in terms of fit and finish. It really irks me in fact. BUT...
-I can easily hold .001"...

After doing some experimenting, I found that the instructions from Tormach did something different.

The 4th RJ11 from the VFD is an INPUT to the PDB board. Meaning, when the spindle is still...

I actually just stopped by my local Tormach distributor and talked for over an hour about options. I got to see the new 1100MX and all the other Tormach products in person.

The previous PCNC1100...

I have an old Series II mill, which is fantastic and has allowed me to make many awesome, pro-quality parts. If I had one complaint, it would be the tool holders (TTS-R8 interface), the relatively...

Hi guys,
My PCNC1100 Series II is having an issue where the VFD turns off during a high-vibration cut. I can restart the spindle motor as if nothing happened.

After some research, people here say...

I contacted Tormach and they said they switched to 8 to get a little more static compression (higher force) and still have the required deflection to release the tool.

I am starting to think the...

I recently had a TTS holder pull out which is very rare for me. I have always followed the clean/lube practices and been able to mill to the machine's power limits and even in chatter situations...

Where?!

Those are really nice fixture plates for sure. I am too cheap to pay $900 for a fixture plate that I inevitably cut into. That's a big reason for my fixture plates, so that I can actually cut down to...

I guess if I have a total stickout from the spindle head of 3 inches (tool holder and tool), a rise in 50 degrees equals .0034". It could really be that simple huh?...

Hey guys,
Following up on this thread with further frustration. I haven't damaged my machine any further, but I am currently working on a project that requires .001" precision in the Z. It's some...

Well here's the final product. I have a lot of very small parts that need to be held down with screws or tape, so the plate will turn into swiss cheese eventually. I do really like those fixture...

Thanks for the input. In hindsight I have come up with about 20 ways I could have done it differently. It's just that frustration that comes along with machining, as I'm sure you all have felt...

Yeah, I wouldn't even attempt that.

I wonder if the dovetails are parallel to the top surface. If so it could easily be skimmed using a magnetic table on a surface grinder.

Good idea, worth checking. I had to turn the machine off for the rest of the day today.

I set the Z zero with a dial indicator tool in the spindle that has a certain height. On the tool I set it...

Backlash is a simple one I didn't really think about. I could probably account for .001" there, since I referenced while traveling in the downward direction, but the tool tends to pull itself...

I set the bottom level at .003" above the table surface, and referenced the zero off the table, so it shouldn't matter what my stock thickness was as long as it didn't do some rapid plunge or...

I've got that terrible sinking feeling right about now.

I was making a new fixture plate for my mill. Basically it's a 1" thick piece of aluminum that is 1/4" narrower than the machine limits, so...

I've been meaning to ask about this for a while. It's always been a hassle for me. The deluxe stand is not angled down toward the drain, so I tend to get 1/4-1/2" standing coolant in the bottom of my...

7075 is much stronger than 6061. Stronger than some steels. But it cuts like a dream and is a lot less 'gummy' than 6061. You can sometimes cut dry or with a basic mist spray. Be wary of the...

Valuable input. Despite tapping exclusively blind holes, I went with spiral point taps since I have plenty of hole depth and they are supposed to be slightly stronger than spiral flute taps.

Now I...

This isn't necessarily applicable to the Tormach, but this is my go-to place on the forum so here it goes.


I experienced a true epiphany today. I've been making metal things for a number of...

I have the stock pump and have found that the reservoir and draining rate can't even keep up with that on bigger jobs. When you change to proper loc-line fittings, the stock pump actually provides a...

My favorite is actually pretty simple. It requires about 2 seconds to put stock in, because it doesnt require any accuracy. Just throw in a chunk, tighten it down, and go.
...

Got to thinking today. Do you think learning to work within the constraints of a Tormach; being forced to optimize for limited HP, RPM, feed rate, resolution, harmonics, and machine rigidity has made...

I would use a 3 flute 1/4", 5100rpm, 28IPM, .1875 depth per pass. That's just extrapolating parameters I've used before that worked well. If tolerance and surface finish is important, you'll probably...

I've heard this before Steve. Not sure I understand. A nice bright finish carbide end mill is super duper sharp. I've cut delrin at mach speeds with it and left a really good finish. I ended up going...

+1 on bull nose

Otherwise I like 2-flute carbide ball end mills. I grabbed some Kyocera off eBay and they work well.
