T-Tech QC 5000 milling machine, PCB fabrication. This is one of my favourite equipment, wish I could get one for home but at $5,000 it doesn't look like I can get one for myself. What use to take me two to three days with a chemical etch-ant process I can do in 15 minutes with an environmentally safe mill. No chemicals! and the dust is collected by a HEFA vacuum system. At work we have 3 machines, 2 pneumatic Z Axis and on electric Z Axis. Machine #1 is over 10 years old and used everyday!
Here are some video's of the mill in action. This is from Texas Tech IEEE.
