Started in '83 in jr high metals class don't know anything about cnc but I'm learning. Got my own shop going about 2 years ago. It's fun and I am learning alot. Most of my experience was on my own except for the last three years of machining class at nmsu. Whats funny is my college prof. in machining was also my high school metals teacher. Yes Guess mine should read exactly what it says a chip sweeper!!!
