In production on the Tormach PCNC 1100 with ATC

[@BrettFleming]

I know this is an older video, but in case someone is still listening. Make sure you're lubing the R8 collet between the collet and the spindle (check the manual). This has a large impact on the TTS holding capacity. If it's dry up there, then the Belville washers are pulling against friction surfaces, and not using their energy to close the collet.

Looks like you can tighten up on your drawbar some. I tighten mine until the tool just barely drops free when I activate the air cylinder. The drawbar, R-8 TTS collet, and Belville washers are wear items and will need to be inspected and replaced occasionally. The quickest way to speed up production with a Tormach is to put as many parts on the table as possible and machine as much as possible before doing a tool change. I have gotten to the point were I don't worry about the time as much as I once did. I fire her up and let her cut, then I go do something else.

Nice video Mike, thanks for sharing. What pump are you using? I'm planning to upgrade my flood coolant setup soon but not sure which pump would be suitable.

The Tormach high flow pump with custom plumbing and manifold

I have designed a similar, albeit more complex TT8 arrangement (not on a tormach, but from same factory) and found that 4 stacks of 4 belville washers is JUST enough for 1HP. I see you have 4 stacks of only 2 washers. 1000lb tension is just enough for 1 HP. I use double stacked washers for extra pressure, AND the fatigue life will outlive me. The service life of washers will be low with only 2 washers. My test is to hold the spindle still and see how much torque is required to make the tool slip. Can't remember the figure at the moment.

This is true

[@multiHappyHacker]

try it at 4k rpm instead of 5k for better horsepower. You might make sure your filter/regulator/lubricator is actually providing adequate PSI, and the air compressor too. The set screw holders are far better than ER20 collets. I don't have tools pulling out unless the load is far beyond what is programmed.

Thanks for sharing this, nice video.

[@RavenRockMachine]

VMC use beville washers for their drawbars..

[@4DModding]

Try a syil v7 or x7

You would have been better getting a used Haas. You cant expect much from Chinese junk.

[@nitchmakes7550]

Eric B Tormach are designed as a “cheap” way to get into CNC machining. These machines are not for industrial manufacturing like Haas or other brands, they’re designed for shops with a small budget. They’re also good as educational machines because they’re less costly for a school district than a Haas or other brand

[@EricB90]

@@nitchmakes7550 thanks for the input. All I'm saying is that Tormach is a shit Chinese machine, which apparently you didn't even know at first. When it comes to machining I personally do not like making fucked up parts, nor do I like to settle for communist made hardware.

[@ghost2coast296]

@@EricB90 what better option is there in the 10k range for someone just trying to get a start? Seems like the next step is buying used industrial but then you're gambling with someone else's headache.

[@EricB90]

Go big or go home dog. Just my style. Hate cheap shit that wont work right. Have too many bad experiences watching shitty machines try to work. If you can afford 10k use that as a down payment and finance a better machine. Just my opinion.

[@Icutmetal]

@Eric B it’s not as much what you’re saying as how you’re staying it seriously devalues your credibility. There’s not a darn thing wrong with these machines if you’ve got realistic expectations for it. Tormach makes no claims to produce machinery on par with even the lowest end Haas machinery. What they’ve done a great job with; however, is produce machines that are reasonably priced and not as intimidating to operate for beginning users, which has contributed to getting more people excited about and involved with our industry.
