machine shop?

Vertical mills like a Bridgeport are very versatile and with the right fixtures can do a lot of jobs. But they are usually going to be slower than a dedicated machine. The problem is in a commercial setting you spend as much or more time setting up fixtures as you do running the job. If you are doing it for a living, I think your going to want a dedicated machine for each type of work or several mills each with their own fixtures or you may not eat.
