The New Aluminum CNC machine

The original Oak machine I built was great but I am ramped up the precision level by a factor of 10 by building a 6061 aluminum frame machine with some really nice THK parts.
The new machine uses a THK FGS 140 and 200 actuator assemblies for the Z and Y axis.
The X axis uses two THK HSR30H bearing blocks and 33" THK rails

My first CNC machine

I decided to build a wood CNC machine first to iron out all the design elements, see what works and what doesn't.
I am using Red Oak for most of it. It's hard as rock, very stable and I had a bunch of Oak in my shop already.
I didn't want to use plywood or MDF, which is basically glued sawdust.
The Z and Y Axis parts

The X Axis and Table

Acme screws, Shafts and Bearings

All the parts assembled and a working router

The first project on the router and my first crash


 

Here's a short movie of the Oak machine below cutting out aluminum parts for the new aluminum machine above

Links to Software and forums

CamBam is a CAD / CAM application designed to take common CAD files such as DXF and 3DS,
manipulate drawings using CamBam's internal geometry engine then produce tool paths and Gcode for CNC machines.
