Folks Of Interest big mill--spindle rebuild

the big mill needs a spindle rebuild after years of machining dies. the bearing are worn out. powered by a 50 hp motor it spins at 3000 rpm

as the photo shows this spindle is bit bigger then your average bridgeport weighing in at a svelte 4000lbs

it will be sent out to a special shop that rebuilds these spindles , est. cost $15,000

 

OK you win, you have the biggest one!

 

I dream of having a mill big enough to bore blocks with.

 

How old is the mill?

 

That tool will not fit in my garage.

 

That’s a good size. I use to build spindles for KT back in the late 70s. The tool holder alone weighed 110 lbs. I now repair cnc machines and have rebuilt some 15k rpm spindles for okuma and some smaller ones for other brands.

NOW YOU VOLUNTEER AFTER THE FUN IS OVER

 

Ahh, from your title I thought you had to rebuild your front SPINDLES because you put a BIG MILL (engine) in your Hot Rod.

 

Remember it’s not the size of your spindle , it’s how you use it !
