Probably why the previous owner moved it…
I bought a Makino today...
- Thread starter Garwood
- Start date
They didn't have any problems with it. They're still running it's 5 axis sister machine.

Call dibbs on that one???
I think I'd get a bigger newer one if I added another hmc. I have no need for 5 axis.
Honestly, you got the better of the two. When I was still there, there was discussion about those two machine's futures. My position was to take the 5th and install it on the machine you got. Both machines were still good mechanically and electrically but the one you got has scales whereas the other does not. Long term it will be a more accurate machine.
The real sweetheart machine there in that same approximate size, is the Yasda. No idea what the last 10+ years since I retired have seen happen to it, but while I was there it had amazing accuracy and repeatability. Of course, even at about 20 years old now it would probably still bring pretty big money if sold.
Every time I was in there for this Makino that Yasda was running. I didn't ask about the Yasda, but I do remember my impression being it was pretty small-Maybe 6" cube part size?
And I looked over the 5 axis MC40 a fair bit and it looked more like I'd expect a 1989 hmc to look.
I definitely got the better condition machine.

The Yasda is an H30i. Approximately 12” cube.

Come to papi
Today was actually the first day the Makino ran all day making parts without any alarms or stupid shit. Half the time it's me messing up some procedural thing like hitting cycle start before MDI'ing the spindle tool. But I did none of that today. Just made lots of parts all day long.
I didn't think it would be much different setting up and programming a horizontal, but there are a lot of little things that are different. Took my brain a little bit for it all to sink in and get used to the Makino nuances, but now we're cooking right along.
Doing a second op on an HMC is pretty awesome. Hitting all the sides. Getting super nice blends because it's not a janky 4th axis trunnion on a VMC. Mucho rigidity. Neat stuff.
Things I've learned- I stuck a Tschorn 3D taster in a tool position and it lives in there. I use it all the time and it's indispensable for weird off angle setups. I don't know how else I'd do it.
This Makino does not rigid tap. This kinda blew my mind a bit, but after a couple broken taps I went to floating tap holders and all is fine.
The tiny coolant pump is surprisingly adequate for everything I've done so far EXCEPT the chips just pile up everywhere. This thing desperately needs help getting the chips to the bottom of the enclosure where the conveyor is. I'm hoping swapping in a big boy 300 psi coolant pump will help get the chips down, but it may need a wash down pump as well.
And the chips accumulate all over the spindle housing and wreak havoc during toolchanges. The headstock has a chunky steel lug the toolchanger arm uses for alignment. That lug is a perfect shelf for chips to pile on. I need to figure out an air nozzle that blows that off before toolchanges or something. It's kinda ridiculous Makino didn't see that as a problem.
The loc-line coolant nozzles really, really suck. I hate loc-line and will be bending up some 5/15" stainless tubes to replace the plastic junk soon.
That's about it I think.

Consider Nickle/copper brake line. Cheap and easy to work with and tough enough for coolant lines. I buy big rolls from Rock Auto.
I don't know how you did it John, but posting that info just made me realize if I took a small, rigid coolant line (like 3/16" brake line size) and pointed it at my toolchanger lug/chip accumulation shelf it would stay nice and clean of chips.
Thanks for the Nickel/copper info and for triggering an apophony!

Shoulda bought an A55 for all that aluminum shit. MC40 is a steel cutter
. Definitely could use a wash down pump in either case.

I couldn't say no to a decent later style A55.
I have plenty of steel to feed the MC40 in time. Right now I have a pile of new products I'm working through and almost none of it is steel.

That's a cool idea, constant washdown.

Are you sure? Some machines want M29 or something like that to sync the spindle.

So were you using G84.2?
My Hitachis use M29 with G84 or G841 alone
My Yasnacs use G93 to sync the spindle in G84
My Mitsus use r1 to sync the spindle but there is usually a setting to so you don't need to call r1 in your tapping cycle.
