I didn't mean to imply that it's impossible, just that is is an incredible amount of work to produce a half-assed metal lathe with simple tools, no matter how you do it. If you do it, document the whole process in a blog with videos and photos, and it will be something I and others will enjoy."

I've used both, but mainly various versions of FANUC (seems to be more common in general). I could go with either though I am much more familiar with FANUC. "Conversational" refers to a type of fill in the blank programming, which is easy and convenient for one off's and such to quickly get semi-simple parts out. I don't know what you want the machine for. If it is just production, then it doesn't make much of a difference. If otherwise, conversational programming is a serious thing to consider."

but remember my tormach was about 10k with 5k of addons and accessories.

Moral of the story is machines are expensive unless you can do it with crappy ones.

Also the 1100M is 2HP with 7,500RPM spindle. I guarantee the Haas is a better machine but at least compare them honestly.

The MX looks to be more comparable. 10K RPM spindle though, rigid tapping, etc.

The chuck is mounted to whats called the spindle, and the spindle should have a hole all the way through the middle, out the back of the machine. Its so you can stick long stock into the chuck, or for precisely what you are saying which is drilling "into" the chuck.

Just have to make sure your spindle bore is larger than your drill bit.
You can do half and flip it around, but that introduces all sorts of problems

Also, there is a stubby drill bit called a "center drill" thats made to put a cone shape on the end of a piece of stock so that it can be used with lathe centers.
Im assuming when you said center drilling, you meant boring a hole right through the middle and not actually using a center drill. Though im not sure if calling it "center drilling" is necessarily wrong either.

degrease it thoroughly then boil peroxide and table salt to dissolve the salt in it, coat it in that mixture to make it rust, then boil (in a clean degreased pot) de-ionized water (water needs no minerals in it) and put the rusty part in it (after washing off salt mixture)

That's why I was thinking about filling SHS with concrete.
Pic related is the basic design I was thinking of for the bottom part of the bed. Pretty simple, it's gotta be big and heavy, but I wanted something that can be taken apart and moved if necessary, so this comes out to five parts, at approximately 30kg each.
I've got some ideas on the bed ways, but it's still formulating in my head.
The middle section, the little gusset tabs I'm thinking will also be good for attaching other stuff there, like the rack for a rack and pinion thing, or for a sheet metal or plastic guard to keep fingers out of twisty bits."

I work at a grinding shop, we have grinding CNCs. We regrind old tools and we produce our own custom carbide tools.
The mill is to test our own new tools and fix problems with regrinds.

We spent 2 years working on getting a contract with this large company, creating a custom tool for their specific application. We made a lot of test tools and just waited to hear back from them on how they performed in real life, instead of text book knowledge. We could have immensely cut that time down by getting the small mistakes out of the way by doing a lot of testing in house.

We also have big name customers in production that have their processes locked down. They know exactly what their tool life from our regrinds should be.
Say they randomly see an average 5-10% decrease in their tool life, they will bitch at us and we will have to figure out exactly what in the tool geometry changed on our end. Doesnt happen much but it can on occasion.

Last time it happened it was something really basic that should have been weeded out quickly in a day, but it took a while sending tools back and forth. On the cutting edge and gash lip of a performance carbide drill, an operator had been putting round hones when they should have been chamfer hones. Round hones are .001-.002 and chamfer hones are usually .003-.004. By eye and under a microscope they look the same so the tools looked normal, but ti just took time of going through the process of making new tools to figure it out. Much less painless when you are doing it in house instead of relying on communication"

There are only a few factories who actually make raw carbide so a lot of brands will have the same exact base carbide. Also realize that there are patents on certain edge geometries and flute construction etc etc.

A lot of tools are close but slightly different for legal reasons, not for performance reasons.

Objectively, there would have to be a "best" endmill, under 100% ideal conditions with your machine and your material. But honestly in many cases itll be splitting hairs, and down to you to actually tune your programs to your application.

Id ignore the marketing and just run them all at feeds and speeds that are recommended by the manufacturer and then stick to the easiest one to tune in well with your setup."

Just to be clear, you will wear through that chrome plating if these see moderate or more use. They may still cut well when that happens, I'm not sure. As more durable metals were starting to make their way down to the consumer grade cutting tools Sears was selling, the Kromedge brand started to shift lower down on the quality scale. By the 1980s it was basically their bottom tier for everything. Eventually, they retired the name completely."

The only way that happens is if the part is in there crooked, you can indicate something center at one spot but still have it running crooked as hell.

Gotta move your indicate down and make sure it's concentric to the rotational center of the chuck.

The boring bar there with the triangle insert in it. Goes a long way, doubles as boring bar.

So apparently the inserts with the second ridge are for certain thread pitches? I've never actually used it like that, I always cock the point to be right with a fishtail thread gauge, and the second point doesn't engage at all.

Nice, very jealous. The Haas of today seems to be a lot better than the Haas of 10 years ago.

NYC CNC did a shop tour of a place that makes USAF jet parts, the video has apparently been deleted between now and yesterday though... Must have been something they didn't want shown.

Anyway, they had been a Mazak shop for years and years until their equipment was in need of repair and it had a multi-month wait time to get it fixed. Haas had some machines ready to go nearby, they put them on the floor and apparently are working out pretty well.

Starting to agree with the Titan guy, who makes parts for Space-X and other Aerospace. 5-axis machines are the new go-to, 3-axis is almost obsolete for high-end work. Less setups to get the work done means less risk involved maintaining fixtures and transferring parts over (chip stuck between fixture and part? woops!). Important for expensive material.

For job shops and smaller shops I'm sure 3-axis will be around for another lifetime."

Before all this, you need references. The granddaddy of all measurement is just a flat surface, like a surface plate. You can get that by just rubbing flat-ish things together until they make each other flatter (I think you need three minimum different things to rub together). Then use that to make straight edges. Then arbitrarily divide said straight edge into some sort of unit (establishing a repeatable reproducible unit itself is it's own long and difficult tale).

It's not extensive mind you, there are quite a lot of other good machines and controllers. Haas actually has a pretty nice controller even if the machine can be on the cheaper side.

Mazak, Haas, and Fanuc are probably the most widespread machines/controllers depending on your area, if you know how those work you can work pretty much any other machine/controller.

Heindenhain is on the other end of the spectrum (on the Agie Charmilles Mikron I worked on).

took my setup down and don't have any pictures, but basically I just took it down to .748 1.5" from one end, center drilled the other end, and then put my clearance diameter in the chuck with the other end in the tailstock. I used my left hand tool to take the left side down to .750, then used a right hand tool to take the right side to .702 without changing the setup.

g71 p10 q 20 d.025 u.02 w.01 f.008
n10 g00 x.702
g01 z-10. f.003
x1.25
g00 x1.5
g70 p10 q20

program was basically this. I measured the part when it was done and reran the g70 line with a wear offset to get it to my exact diameter. I was too afraid I fucked it up to thread the middle part right then so I tried to indicate it in a 4 jaw on a manual lathe, but I couldn't get it straight. I ended up indicating at an arbitrary point on the right side, cutting my threads, and then taking an extra .02 off the left side hoping it would at least get those two features concentric."

But if you bought a rotary converter from AR then you should learn how to grease the bearings properly.

There's a set screw on the bottom of the bearing housing at each end that you remove before pumping grease in, it pushes the old grease out through the set-screw hole so put a paper towel or something under it to catch the old grease.

The guy obviously does not have a lot of $. He mentioned at one point some of the guys around there were interns (I assume unpaid). What I find super interesting about the guy is that he is successfully bootstrapping himself. Lots of people talk about it, but he is doing it.

Not that I am any sort of badass, but I get the feeling most of his work is not exactly tight tolerance.

Anyway, I don't think he can afford to drop $250k - (big fucking number) on a mill turn, and does not have a business model to justify it.

I have a 3/8 steel plate subplate I'm going to make some T slot keys to fit to the table for, and on top of that aluminum flat bars with clamps and pins to hold the aluminum workpieces."

mitee bite locating rails are some hardened steel for backing up stuff on aluminum fixture plates. Definitely not going to pay $35 for a single 10" piece though. Damn, they aren't even hardened.

Tormach owner here.

If you're a trained machinist you'll hate having to slow things down and make compromises on the tormach.

If you're just starting out the tormach is a good choice because you'll save way more than 5 grand because you'll be spending 30 dollars per tool holder instead of 100+. You don't have to worry about 3 phase power or if your concrete can handle the weight. If you break something you can fix it yourself and don't have to have a technician do it. The rapids are slower so if you mess up your offsets you won't be as likely to wreck the whole machine. etc. etc.

I've actually worked with nice machines so I get frustrated with my tormach, but at the end of the day I realize I am making all that I want to and for way less money, I'm just not making it at the speed you'd want if you had to make 10,000 of a part."

Weight is important but not everything.

Ways always come in pairs and the further apart you can make them the stiffer the saddle will be.
Will you buy linear rails?

High end machines use both cast iron and a concrete materials together so that the rates of expansion and contraction and flex work against each other.

Just like everthing DIY buying some cheap Chinese product is cheaper and faster and make work fine, but if you want to have fun and learn about machine design, I hope to see you build something cool!"

Oh yeah, in section 3.4 of the gtri document they recommend not specifying the dimensions of fastener holes or related cbores. That's just lazy, and will cause you problems later. Look up proper values (tight vs loose) from the machinist's handbook and use them in your drawing.

Re computer speed, even a $500 pc can run CAD just fine. The software is what is expensive - I think lots of software vendors are doing free/low cost entry level things these days to get you hooked.

I started with pencil and paper, but full parametric 3D CAD really is the only way to go in the end. The old pencil and paper skills are vastly under appreciated these days - though NOT for drawing creation. A drawing is really a specialized language to machine shop, and until you have thought about all machining opps and tolerance stackups, etc, etc, etc. and communicated this by your drawing your design/engineering is not yet done.

As far as the projected drawings go, parametric CAD makes that super simple. 3d model to 2d projections is a button click or two, then the dimensioning and fab notes can take forever (normally this is where I figure out tolerance stackups and finalize dimensions).

By all means, work with paper now, but as you get serious I think you will quickly find modern software tools amazing. There is nothing wrong with knowing the old methods though, and old hand lettered drawings can truly be things to admire."

>I'm from a 3rd world shithole, $500 is a fuckton of money here.

gotcha. This means some of my advice is wrong.

Note that the gtri document is going to create kind of American style drawings. They recommend using 3rd angle instead of 1st angle. This is the way God and Mr. Ford would have wanted. As far as I know the rest of the world uses 1st angle projection, which is really weird, but that is just the way it is.

In general American drawings tend to really speak to machinists with lots of fabrication related notes, whereas eurofags have more highly regimented dimensioning and tolerancing standards. I prefer the American style drawings, but you should do what you have to do. In general a proper drawing in either style fully specifies every dimension and has a tolerance for everything.

Take your best drawing of a part you want to a machine shop when they are not super busy and odds are they will tell you what is wrong with it."

The rails I'm still thinking about. A lot of the stuff I'll try to find scrap or cheap stuff for, but the rails will probably be new for quality's sake. I read a little about rail geometry, and was initially going to use round bar even though that geometry isn't really ideal, but now I'm leaning towards a triangular shape. If i used square bar stock, rotated 45°, then welded onto a little bit of plate to attach to the rest of the bed, I could make the triangular rails quite easily, then I can just get some telescoping matching SHS for stuff to go on the rails, with a corner ground off.

This rail design could either be double sided and sandwiched between the two SHS', or single sided and bolted to the attachment points. I noticed that some lathes have a third or fourth rail, which I could also do. Then if it's three rails, the pinion could go on the free spot.

>N.B.: there'll be a lot of welding in my design, because I bought one and want to git gud at it"

"How can I get something flat and parallel without a surface grinder?
I have a milling vise and the hard jaw was thicker at one end by a couple thousandths, enough that parts would slide down the other side because all the clamping force was on the other side.
I tried lapping it with sandpaper flat on a granite plate, just putting pressure on the thicker edge, checking it with the micrometer often and changing where I pressed down on it and how hard.
Doing it that way I got it so that it's equal at both sides, but in the middle it bulges out by about half a thou. When I keep lapping it, it's just removing material equally from the whole surface when I put pressure in the middle.
it's probably good enough where it's at, but if I wanted to get it flat to that extra half a thou, how would I do it?"

GD&T is a complicated thing. For concentricity your datum isn't part centerline, it's centerline of two features. If he doesn't have a V block, what he can do is mark it out on the part. Find the high side and low side, if they're in the same "pie slice" from the face of the part then it should be concentric. The way he's checking now is just giving him runout/circularity."

The edges were easy, but the middle isn't because any pressure I put on the middle ends up distributed over the whole surface as it rolls back and forth slightly.

Yes. Usually this only happens when you take a part out and put it back in to cut the other feature but if you cut one feature and something fucks up your alignment that can cause it too.

You apply light pressure downward and just roll it. Do it gently and stop every few degrees. Unless your surface finish is total ass, it's not that hard once you actually have your hands on it and try it."
