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 Ball Screw upgrade - 12/01/2008 The new machine page 4 The new machine page 3 The new machine page 2 The new machine page 1  Click on image to see larger image |

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 CNC1 Movie |
