Which milling machine model?

Some of my bigger cutters, 1-1/4" inch shanks

 

A quick test is that tungsten carbide is only weakly attractive to neodymium supermagnets due to a small amount of cobalt binder used. Tool steel is strongly attracted to the point you might cut yourself on the tooling or chip the cutting edges if not careful.

 

Unsure the weight. They can load it on a trailer in their end and I found a business down the road that has fork lifts that can unload it into my garage. Not sure the weight I'd guess 5000 lbs? Will have to research it.

I'd like cnc. I need to do research on it more. Seems like a lot of the cnc machines use old computer software and cannot be repaired. So I might be better off buying a good machine and upgrading it myself with a servo kit? At least that way there are more options and up to date technology.

Alternatively I could try sell all the cutters and just buy new ones for a smaller machine but that is a lot of work to sell individual parts.

I use steel mostly for projects. The 940 seems to work well with aluminum but would it with steel?

 

Here's another cinncinati. It a 5 hp machine, 4500 lbs. Seems in good condition via photos, price negotiable. Not sure if this is the one I'll get just looking at available options.

 

Now that is alot of machine, what I always do is try and find the operator and service manual before I buy just to get an idea what I can do with the machine. I looked on vintagemachinery.org for this one not seeing it.

(1) Cincinnati Model 210-12 LL Dial Type Vertical Mill, Ref #78-484 - SOLD - YouTube

 

Minus the stuff with the taper, I didnt see much there a bridgeport wouldnt turn. I'd keep the end Mills, the broach stuff, sine bar, circular cutters and ditch the rest.

That machine is nice, but the reason its 2grand is no one wants it. I bet I can find 5 people today by 6pm that would want my nasty ol bridgeport. Moving that cincy and powering it is a big issue. Neither is cheap to do. Trust me pal, I'd walk away from that monster.

 

That big cinnci is a heck of a machine.... But It's a big girl! I have a big shop and I'd have to think twice about it. Mainly because I don't have 3 phase service. I'd have to spend 2x the cost of the mill on a Rotary phase setup (yes I could cheap out and cobble one together but really just want to use the machine not putz with it in my limited spare time).

 

Nice machine! Better be! $5500 is pretty good amount of dough. I bet those ball screws were a couple grand for that thing.

 

Thats exactly the kind of machine I'm looking for! 5500 is pretty steep but I would love to have one in that condition. The table even looks like its been scraped flat.

Is 2 hp enough? Am I obsessing about hp too much?

In terms of power supply, why a rotary? Won't vfd power supply work too?

I figure no matter the 3 phase option I choose its going to be pricey. Lucky I already have the power cable from the scrap yard.

 

Mine is 2hp on a cheap VFD. No complaints on power at all!

 

On a bridgeport? Me thinks so. It's not really stable enough for heavy hogging. I also have a 2hp BP on a VDF, works like a charm. The BP electronics is single phase, so the VDF is wired to the motor only. The coolant pump needed a capacitor though.

 

UGH... this was a good deal! https://www.pciauctions.com/archive_item_detail.php?item=914089&auction=3864
That's the next toy I wanna buy.

Zap you should have been all over this like a hobo on a ham sandwich! https://www.pciauctions.com/archive_item_detail.php?item=914091&auction=3864

That was a really good auction and stuff went dirt cheap. Not always the case at these as people tend to get stupid.
