Installing a Turret Mill.
Hi all, what are the requirements for installing a milling machine that weighs a ton. I have searched this and other forums and the interyweb, but not much info out there. Is it place it in its position, mark and drill the holes in the floor for the hold down bolts and put the inserts in the floor. Then using a machinists level, adjust and shim the 4 corners until the table is level, left to right and front to back and bolt it down? Have I covered it all or is there some other tricks to consider?
Your thoughts.
Rgds,
Crocy.

Hi Crocy,
As long as the table is reasonably level and the concrete floor is sound, just drill through the fixing holes and use resin fix bolts or expanding bolts to fasten the machine down.Best Regards:

Plonk it on the concrete, if it rocks then put some packing under it.
Then use it. It is not something long, slender and bends like a banana, like a lathe.Gold, the colour of choice for the discerning person.

To be honest, depending on the work pieces you intend to be working on and the size of the base, bolting it down is possibly optional. Ive not bolted any of my machines down as the cutting forces arent going to move the machines. The only one I would consider bolting down would be the lathe in case you are turning eccentric or as happened in the apprentice shop when I was there, the machine picks up a big bundle of swarf and starts jumping around... 2 ton of machine rocking around was rather eye opening...

Have never bolted or seen a turret mill bolted down, and I was involved in moving machinery for a lot of years.

Hi Old Croc,
I thought the reason for bolting down a turret mill was largely in case too much weight ended up on one end of the table and then the table moved to the end of travel and then the whole shebang gets so far off balance and tips over? You might not make that mistake, but someone else might. That could be as simple as having a family member (i.e. young child copying an adult) turning the handwheel to see the table move.
I am assuming this is a manual mill and not CNC
Chem set bolts are good to use, though the ones I've seen might not be long enough, perhaps longer ones are available on special order?

They can take a bit of weight without toppling over.

Well, actually no I have not. Gave it a run that's all to check the power feeds and the DRO.
I posted this on some other forums and a guy from Canada said seeing I was starting out to raise it 100mm, so I don't have to stoop over all the time as I mainly do smaller work. So I milled up some spotty gum, plonked it on it, shimmed it and put 2 bolts in the front side for peace of mind. I am back milling timber at present, but I will get back to it soon.
Thanks again guys,
Crocy.

Generally the bed will bind up if too much wieght is placed on a turret mill.
if you must bolt a machine down use loxins nothing else, unless your workshop has access to a fork or over head crane. Dynabolts or chemset threaded rod is a disaster when it comes to moving it having to jack up and cut bolts etc.
