Brought CNC Mill Home... Won't fit in shop!!!
I picked up my Lagun 3 axis CNC mill yesterday and got it home only to find out it is too tall to fit in the shop... sigh. The only option for me is to remove the head and then get the base into the shop and reattach the head to the mill.
My only question on this is the effect on the tram of the mill. My other mill is a manual machine and is of course adjustable for tram.
So if I remove the head will it effect the tram or is it a matter of reattaching the head and then tramming as much as I can before I tighten the bolts that hold it to the mill?
I envision some type of dowel or alignment pin inside the casting to set this but I have no idea?
I have attached a few pictures so you know what I am dealing with and any help will be greatly appreciated.
Thanks,
Steve

Will it fit if you just remove the pneumatic drawbar actuator and the motor?

Glenn,
That was the original plan... but still too tall.

the stud with the nut shown in the picture is most likely a taper pin that locates the head. If the head is lined up now, removing it and re mounting it should not effect whether it can be retrammed

Make a couple of "witness" marks with a center punch or cold chisel to relocate it properly.

For a machine tool, that would be useless. The slightest misalignment (not discernable by eye) is greater than can be tolerated. Were that not the case, DTI's would not be required to dial in the head on a vertical mill.Al_Messer wrote:Make a couple of "witness" marks with a center punch or cold chisel to relocate it properly.

Just a long shot. Do you have any controlled way to lay it over to take it through the door on it's side or back without taking the head off?

Yep! I agree. The only caveat, in my opinion, would be to insure that neither of the flanges sustained any damage in handling. I'd dress each one with a single cut file (draw file only) before re-assembly.JHenriksen wrote:the stud with the nut shown in the picture is most likely a taper pin that locates the head.

I know it would be heavy, but could you remove the ram with the head still attached and then re-mount it without losing "tram"?
In an even less practical thought I was thinking that, as punishment for not having measured the height, you should be forced to give the machine to the closest HM member who has the space LOL!

one way or the other you will have to tram the head as part of the checkout after moving it.
i vote for lifting off the head assembly carefully and reataching it after its inside beside everyone needs a chain hoist above the mill, right???

I'm curious if it would be easier to dis-assemble & re-assemble shop doorway rather than mill.
I took 8' of a wall off my garage to get my CNC mill in.

Resquaring the head should be the least of your concerns.
Here is how I got my Bridgeport into my garage. It was 4" to tall.
Is this your problem?
I mounted a 3/4" pin the the machine table. I used the knee to raise and insert the pin into
a 3/4" toolholder. Unbolt the head from the column. I used the "Y" axis to move the head a couple of inches away from the column. Then use the knee to lower the head enough to move the machine inside the garage. Once inside use the knee to raise the head back up and reassemble.
My Bridgeport head weighed 800 lbs. If it falls on you it will likely kill you.
Before moveing the machine I supported the head with a small bottle jack and tied the head to the column with ratcheting tie downs.
I removed the Z stepper motor rather than unwire it and laid it on the control cabinet. The spindle control wires I had to lable and disconnect then reconnect.
If you know exactly what you are doing I have heard of guys doing all this in 45 minutes. It took me all day.
