I work for Cozzoli Machine Company in NJ. 19 years now. I started as a
trainee and now run the CNC department.
I took 6 years out of the shop for the company and did lots of IT work,
Networking the PCs and RS6000 as well as connecting through leased lines to
our sister company in WI. (now closed).
We are looking to buy Haas machines soon. We LOVE our Cincinnati machines ,
but they have changed to a Fanuc control and getting parts and repair is
becoming a pain in the ass. Not like the good old days. Now I know someone
to bother with questions if/when we do get Haas machines ;-)
