Home built CNC mill #2

Hi;

Just showing a progress report on my second CNC milling machine. I'm using 550 oz/in steppers and Gecko drives with an Axuss control board. Hope to have this puppy making chips in 2 weeks. Waiting on the boards for the most part.

Travel in the x axis is 24" and 14" in the y axix. The z axis has square gibs for more ragidity. Notice the head is mounted to a moveable ram for even more capacity. The "Z" stepper is just out of the picture. All that is left is intalling the feed screws and paint the column.

The spindle is 1" hardened and ground A-2 mounted in roller bearings. The spindle will only accept 3/8 shank tools for rigidity reasons.
