RICH'S ATLAS CNC CONVERSION

[RICH]

This is a 38 year old Atlas Clausing Vertical Mill which I rebuilt and converted to CNC 4 years ago.
Six speed ranges / 24"x 6" table / 15" x 5.25"  cross travel / MT 2 taper in spindle.
The guard is removed to show stepper mounting. A handle extension was made for the quick feed
( in-out to engage fine feed) and a 85 in oz stepper was mounted directly to the fine feed, thus total manual
operation is still available. Motor side of the x and y axis have double contact bearings in the bearing blocks
with a single contact bearing in the other bearing block. Nuts at handle ends provide for preloading adjustment of the bearings.
200 in oz Superior Electric steppers on the X and y axis. Three axis digital display along with an indicator for quill movement. Not much room for the ball nut as shown by the picture. Ball screws 16mm -5mm lead with adjustable ball nut by Techno Inc. A 1 HP DC motor with variable speed controller still waites for me to installation.
Overall dim of 36"x 40" x 70" provide for a nice homeshop mill.
