Well working with CNC is another story!
|And now, a word from our sponsors:

"I am using a CNC machine to machine the phenolic, and it is not too hard on tools, nowhere near as tough as circuit board"
What are you using for a machine?
What are you using for bits?
What kind of feed rates?
We have a Shopbot and recently burned out a high speed air spindle using it to rout circuit board.
I replaced the air spindle with a Bosch router. It must be the increased torque, because even at a lower rpm 25K instead of 65K, I can maintain almost the same feed rates.

I am not personally using the CNC machine, I don't own it or operate it - I use a local service shop whose main business is signwriting and engraving faceplates for machinery.
The phenolic I am using is much, much softer than circuit board, so a regular 1.2mm router bit is used, and the feed rate I would estimate at about 2cm/sec. As I mentioned before it is the epoxy phenolic that is very, very hard - similar to Corian or Micarta.
"I am using a CNC machine.." was just short-hand for "I am taking my phenolic down to CNC shop and having them use the CNC to cut the phenolic to my specs"

Do you want to sell me the air spindle?
Can you tell me more about it?

Sure, send me an email.
