626 milling machine converted to CNC - RobWilson - 06-05-2012

Hi Lads

I am in the process of converting my 626 milling machine to CNC Big Grin

Work done so far ,, http://madmodder.net/index.php?topic=6037.0

Picked up a couple of 8mm pitch/20mm timing pulley's tother day for the Z axis .

Part machined up the mounting block for the Y axis nut to see how much room i had left to fit the Z lead screw pulley .

mmmmmmm there is no room to fit the pulley Slaphead

I can turn the nut 90 deg that would give me another 7 mm to play with . Wont look as nice Slaphead

I was never impressed with the section of casting that houses the Z axis bearings , and there was not allot i could do with it as it is to fit the new bearings ect ,,,,,,,,,,,,,,,,, so i removed the offending lump Popcorn

No going back Rotfl

Hey Rob - just started reading the prelude on Mad Modder. So far it is looking good and I am looking forward to reading the rest. I really should visit that site more often.

Too bad I didn't know you were up in NCL. I would have dropped in when I was there. I'll look you up next time!

Evening Lads

The two lugs that i had left on the casting will be used to mount the new Z axis bearing support Popcorn

Using my HZ arbour vertically allowed me to reach into the casting to machine the lugs . Big Grin

Now i have something to work from :med:
