You need end-boring too in order to train in how cabinetry
is manufactured, which some CNC machining centers will do.
Some shops face bore on the CNC and end bore on a
32mm horizontal boring machine.
$30k is really not going to go far for a real industrial setup
with tool changers and all the power requirements and
a couple of 10hp vacuum pumps to keep the sheets
in place.
For instructional purposes you might want to consider getting
a couple of smaller machines. Students will want to use
them for cutting out guitar bodies, printed circuit boards
and other hobby projects that interest kids a lot more
than nested cutting and boring of parts for melamine
cabinets.
In PA I would buy from a dealer on the East Coast if I
were you.
Another option is to buy used. You might want to look
into buying used from a local shop doing an upgrade
where the seller agrees to help set it up and remain
on call for troubleshooting.
