Attachment 422704
I built this machine to cut wood, aluminum and mild steel.
The frame and gantry are steel, the Z axis is mostly MIC6 aluminum.
The X and Y axis are chain drive and the Z axis is ball screw.
I use linear ball bearings everywhere.
I can cut up to 22" x 14" and I hold repeatable tolerances of 0.002"
This is all custom made and the final tally was just under $4,000.
All the parts are purchased from eBay, amazon and automation direct.
I can change the spindle from the mill head (pictured) to a router head.
My free travel speed is 300 in/min (I've had it up to 600)
