I removed the ACME screws when I converted my mill. I replaced them with
ballscrews. The nuts are platform-style, rather than cylindrical.

I have plastic on the Z of my CNC Router. It doesn't move too fast.
For the fussy or perfectionist water cool. Probably water cool the
ballscrew as heat conduction will be far superior to trying to cool the
acetal nut.
Yep! I just fell out of the trees and damaged my head. ;-)

There is a GTEN RSH ballnut in there. They are rather slim but have an

The backlash removal will be a major project.
This is what the bronze ACME nut looks like. Clearly no way to split it and
add any sort of backlash tweak.

The pin on the nut fits into this hole.

The aquaium pump should keep the sump aerobic. I suppose adding a bit of
peroxide from time to time would do the same thing. If you let the sump
go reducing (anaerobic) then the beastie that grow make volatile fatty

Hi Andy,
I have a box of those connectors in a 6 wide and will get a box of 1
wide and two wide.
My thoughts are when used outside in a marine environment to glop some
3M Scotchcoat on them. Of course that make them rather fixed but they
are cheap. :-)

Thanks. I'll look into that coolant. Seems such a waste not to use what came
with the mill.

Hi Andrew,
The max my mill will run is 3000 RPM. And because I made my own pulleys and am
using a stock V belt there's a bit of vibration at that speed which I don't
think helps much.
The other issue is backlash on the X is over 0.020" so climb milling is out of
the question. I've had a few

Just get modern coolant.
I probably don't even use my mill ever month, and the coolant in

You can get glue-lined heat-shrink for a truly watertight joint.
I bring the prox leads back to a watertight junction box, and in the

I buy dlc costed aluminium end Mills. From my Chinese supplier.
In my Linuxcnc controlled machine I use these feeds and speeds. For a 3
flute 10mm dia cutter. With Dlc. (diamand like coating)
High speed aka fusion 360 adaptive clearing
Depth of cut 25mm
Side width of cut. 2mm
10k rpm
Or from the servo drive suppliers. In China you can get good quality
aviation connectors for like 7usd.
That's what I use and I buy cable from them to.
I have a guy that buys it all up for me and ships from one place.

John,
I always use single flute router-style cutters (Accupro, from MSC Industrial
at www.mscdirect.co.uk) which are specifically designed for machining aluminium
and are highly polished so the aluminium will not stick to the flutes. These
are jolly expensive cutters, and other makes are
I used the big 1/2" one for the large pocket and the smaller 5mm one for the
smaller pocket and profile. The surface finish, given my crappy cast

I bought a number of the prox switches to retrofit the lever micro-switches.
Can't find them anywhere at the moment nor can I find who I bought them from.
So sad...
I did make sure what I ordered could be wiredin the way that a broken wire
would be the same as tripping the limit.
