thanks for the info! it sounds like you will have a pretty solid setup then for that budget. I know there are desktop CNC's on the market for Aluminum milling, which i might have to settle for in the beginning, it just would be nice to also have steel capability, but as you are explaining to me that seems very difficult for around $3000.
Are entry level Tormach's good quality? ive heard that brand a few times as far as beginner level home garage mills and CNC's.
My take on a Tormach. I have a pcnc 1100s3. I've had it now for about a year, and bought it used, from someone who ran a small part time garage shop business with it for 6-7 years. I am a machinist by day, and currently run a fleet of Haas mills of various sizes (vf2, 3, 5, 6), and a nakamura lathe (plus manual stuff). I have also run a variety of other industrial machines over the years and no way does the tormach come close to even a small haas. That being said, I still like mine, and don't regret my purchase at all. I bought it used for less than half of a similarly optioned new one, with a few thousand dollars in tooling, upgrades and other goodies. I'd buy it again, but I'd have a hard time springing for a new one. PO went nuts buying all the youtube family upgrades and stuff, which I got barely used, for pennies on the dollar.
Pros
-It's a complete plug and play system with great support/community behind it.
-Small enough to run on easily available household power, and be moved around effortlessly with a pallet jack.
-Takes up less room than a small haas, which allows more room for other tools
-Fully capable of cutting steel, and other metals when used
within it's capabilities. Youtube is full of both good and bad on this from people who don't know what they're doing saying they're complete shit, to the fanboys who think they are the holy grail with zero faults. IMO It's an adequate machine when used properly.
-Pathpilot is a pretty user friendly control with some great options that I actually like better than Haas. It has some parts I don't like though....The conversational is something I've really come to love. Our Haas' at work don't have quick code, and I really wish they did after running mine.
-Parts are relatively cheap and available, and you can easily fix them yourself. I haven't run into anything major yet, and nothing that wasn't my fault.
-It doesn't need a constant supply of air. My little quiet compressor is enough to run the toolchanger, and blow chips away.
-Don't listen to the people who say it's only good to 0.005". They're terrible machinists if that's all they're getting from it.
Cons
- I
hate the stand/enclosure. It's too bulky and useless. Mine has the half one, not the full upper enclosure. It's unnecessarily big in width, but too short in depth. The coolant system is also an afterthought, and inadequate. I'm planning on someday completely redesigning it from the ground up. The vise sticks out from the enclosure so you need to be mindful of that around it, lest you take a vise handle in the pecker.
- Spindle could use a few more ponies/rpm too, but that's my complaint about all the machines I've ran.
- I don't like where the control cabinet is. Again, it's an after thought, but having it in the machining envelope being sprayed with coolant isn't the best solution IMO.
- The r8 spindle/tts system is "ok". Not great, but a decent compromise between speed/efficient toolchange, and rigidity, and adequate on a machine of this size. Again this goes back to using it within it's capabilities, so if you keep that in mind it's ok, but if you push it too far, it'll ruin your day/tools/workpiece. I'd prefer the bt-30, but mine came with 50 tts holders, so I'm not switching anytime soon.
- I don't have a toolchanger, so small production runs suck.
- I have my gripes about size and travel, but it's not too bad I guess. With a 6" vise on the table you lose too much valuable y travel and you can't hang the back of the vise off the table to accommodate for it, as it will hit the column. So the bulk of it hangs off the front, and you lose the fixed jaw thickness in y travel. Minor gripe, but IMO something I would think of when designing a machine from scratch like that. It's also a bad chip compressing spot you have to watch out for. I'm thinking about making a new thinner fixed jaw for my vise to gain some travel back. The rigidity i'd be giving up, doesn't really matter in the grand scheme of the Tormach, so the added capacity is a big net gain. Of course a pair of 4" vises would probably be a better solution and one I'm thinking about too.
-Size/travel again, While it's a relatively small footprint machine compared to industrial ones, it's a big footprint for the actual travel of the machine. It could have been designed much more space efficiently. It feels like afterthought, layered upon afterthought, with another afterthought thrown on top for good measure.
Someday when I get a bigger space and need another spindle I will upgrade to an industrial machine. BUT I only have a single car garage shop right now, with limited power. The Tormach is the perfect machine for me at the moment. I'm using it within it's designed capabilities and it's working out just fine. Took some playing around at first to see what I can get away with and adjust my expectations to what I'm used to, but I'm very happy and satisfied with the results I'm getting from it. I like that it doesn't dim the lights, and I can barely hear it in the house while it chews away at stuff out in the garage. It does MUCH better in steel that I thought it would when I bought it. Just slower than what I'm used to. I'm ok with that. I do different work at home than I do at work, so the only issue is re calibrating my brain while programming lol.
I can't ever see selling mine. Even if I do upgrade to another one at some point, it would become a great support machine for little quick and dirty parts, and prepping of stock. I don't think i'd buy another one (unless it was dirt cheap), as I really want to move into a full enclosure VMC as my next machine. But for what it is, it's been a great addition to the shop. I don't seek out work for it, but a few jobs have turned up and so far have provided a little side income which is nice. Someday when i get caught up on projects I am going to redesign the stand/enclosure/coolant system for it, as that's my only really big gripe about it, but my expectations are unreasonably high, I get that.
