CNC PCB Mill

The goal was to create a CNC Mill that could be used on Printed Circuit Boards. The issue with these boards is that they are never flat, the have veriation in the thickness by as much as 10 thou, this means with a 45o cutter your width of the space between traces veries from 10 to 20 thou. 10 thou is often the spacing between traces and the traces are often also 10 thou. This means you will cut your traces from time to time. This mill will have a floating Z axis of up to 1/4"


This mill is mostly done now, I will get the photos together and post them.
