Just measured mine, hitting 6000mm/min X & Y 3000mm/min Z
Not crazy fast, but only has a 200x200 work area.
Oh, and cuts steel like butter.

Oh, and it makes chips (takes a while for spindle to register full speed.... needs an encoder)

I think.... I'm about finished.
Except for
- Coolant
- Mister
- Compressor
- Feeds and speeds
- Cleaning electronics cabinet
- Better cable...
So, there has been some more movement. I added an old desktop PC (With a 5.1 surround sound system because, why not). Spindle coolant is in. Made a mister (although that needs testing) and it's had...
Cheers :) The shaft couplings will suffer some torsional stretch, but unless it becomes a problem during test, I'm going to ignore it :)
I'm planning on doing some acceleration tests when the mill...
IT LIVES!

Bit more work getting the last of the Z machined and fitted. But in theory, this thing could start cutting with the electrics. So, machinist hat off, sparky hat on.

Yea, Stout is a good word. Thankfully, I didn't go too big as doing anything this size on a Chester 626 mill requires some horrible setups.
Managed to get the spindle mounted, only to find I've...
With the Z mounted, the next thing to do is make a mounting bracket to hold the spindle to the saddle. I'm putting the spindle in the middle of Y movement for the biggest cutting area, which means it...
Dude. Legendary build. If i ever get around to a gantry design, I'm going to be taking some inspiration from this thread :)
And yea, the round rails are a weak point. Not so much the rails...
There is something nice about being able to take scrap blocks of steel and make them into something usable :)

Can't wait to see what I can do with a CNC.
Got the Z linear components finished over the weekend. Despite some initial worries that some of the components may not be square enough, playing around with the 20 adjustment bolts has left it with...
Could be the motor shaft has bent then? (I assume this is the X2 with the belt drive between motor and spindle). Try taking that out and measuring runout of the pulley. Or, remove belt and try...
Is your steel going to be solid, welded or bolted plate?
Looks nice, I've got my eye on a lathe build when I've finished the minimill.
Not familiar with the machine, but maybe your tram has been trashed? would lead to scalloping on face cuts (inc. re-cut) and very thin surface re-cut on edges, maybe leading to the screeching.
...
So, the X&Y assembly hasn't been touched for about 5 years, hence the surface rust.
As for the Z axis. It's been the most recent work (read, last month of so). And that has gone from nothing but a...
So, these are my steppers, reclaimed from a skip. Does anyone know ANYTHING about this brand/make? Greatly appreciated if you do, all I know is that it's a FEA2M55 :)

Well, as of this evening, this is the state of the mill, dummy steel represents Z.
Base is a solid plate of cast iron 50mm thick with 25mm steel plates either side.

Confirmed...
Just quickly before I head home....
I think it's a Taig bed. The linears are 20mm THKs I think (This was all back at Uni and details are sketchy :( )
Z will have 15mm Hiwins and 15mm ball screw....
Started on the Z. construction is a 100x100, 10mm wall box section steel with 25mm plates bolted to either side for the rails:
400430 400432
400442 400434
400436 400440
400438 400444
So, I started this project back at uni, 12 years ago.
When I graduated in 2007, this is what it looked like...

It was a shiny beast back then, surface ground blocks of...
Accumulated hours spend de-scaling kettles, pans, pipes, toilets and cold water tanks kinda gives me an idea about how hard the water is in my area.
I like this synthetic coolant. Don't suppose...
So I just purchased a 1.5kW water cooled spindle motor for my self build mill. My question relates to the 'water' part.
I live in a hard water area, and really don't want to risk furring up the...
I didn't realize all that. Thanks for the info dump.
I did mean full rail to rail 0v,5v outputs. Wasn't aware that TTL was so grey.
I guess it wouldn't be difficult to add a variable amp at the...
I've got a lot of ideas, and a lot of designs (I think my archive is up to 50 now). I just lack the time and money to implement most of them.
Once I sort my site out, I will be putting projects on...
The functionality they've managed for the given cost is remarkable. I doubt I'll be in a position to compete with that scope for quite some time. I can foresee the development costs being quite high....
This will be, depending on its success. The first of many products in a range I have in mind. Including a computer based oscilloscope, power supply, wireless Data links, analogue sig-gen... etc.
...
Oh, thanks for the feedback.
Ok, so, on the flip side of the coin, what would you be prepared to pay for the functionality I've described?
Size restriction is my enemy here, as I'll be...
Hello there, I have developed a project that I have been in need of for a while, and am considering taking it to production. I'm trying to get a feel for the market before I push ahead with it as the...
Wow, thats cool. I really want to see if my mill will be able to engrave marble/granite and the such when its done.
I will keep in mind what you've all said about the splined shaft and provide...
