Guys,
Has anybody seen a J head mill retrofitted with a NMTB 30 spindle. I have 2 Mills ( 1 manual and 1 cnc) with the NMTB30 spindle and I have a ton of toling and plan to get more. the parts from the variable speed heads may be interchangeable with the Boss mills. some of the other parts are.
any thoughts ideas

Thanks

The QC30 spindle was an option I have seen on many EZTRAK machines which of course uses a 2J head. So there should be no problem.

Thanks george. would that be a Quick switch 30 or a NMTB30 with a power drawbar like my R2E4

strait NMTB30 would be prefreable to me. shure would be nice to have all the tooling be the same. as my 2 other mills.

I am looking around for a seriesII special with a Jhead (not the VS head) to run with a VFD. I only have single phase. and when I get the R2E4 retrofitted it will be running single phase as well

I just sold one of these R8 to NMTB-30 adapters:

This would be easier than replacing the spildle.

It came with the tooling I bought for my NMTB-30 equipped V2XT Bridgeport. I don't have room for another machine, so I sold it.

Also- I only have single phase at my house, but using a VFD is really the way to go. Great pricing on a new one here:
For a 1 HP head:

for a 2 HP Head:

The wiring is simple, and mine works great.

are those 3 phase full time or does it drop a leg when the motor is spinning

holbieone-
They are 3 phase full time. It is not a static or rotary converter, and it makes the 3 Phase motor variable speed. You will only have the rated HP of the motor at it's intended full speed.

There are many many threads on this site that talk about VFD's. Just search for it, and you'll find nearly everything you need to know.

thanks, i'll look into it

A VFD or variabel frequency drive is 100 percent 3 phase their main purpose was originally just to start stop reverse and control the speed of a 3 phase motor from a 3 phase supply. these have been around for a number of years. on motors of 3 Hp and less it is possible to buy VFD's that can be fed with single phase (without de rating) and will give us home shop guyss the added benifit of converting from single to 3 phase.
Hope this helps.
