Milling Machine Advice

[Clive S]

I converted this mill about 9 months ago using the existing screws. with 3.1nm motors and now
I am just changing the lead screws to ball screws if this helps on my Warco WM-18 mill I will be use 1605 screws.

I machined a slot out under the X table with my router very slowly 1mm DOC 200mm/min with a 6mm carbide 4 flute at 5500 rpm.

The yellow endplate on the X table will have the boss taken off and the hole opened out to 42mm, then a boss will be made to insert into the 42mm hole.

The boss will then have a 32mm hole cut out for the AC bearings offset by 3 mm to bring the screw up into the machined slot under the X table by that amount.

The Y screw will fit using the original boss just opened out to 32mm for the AC bearing.
Then of course there is the Z to think about. ..Clive
