The HAAS VF-2 Vertical Machining Center requires training. Nothing else in the machine shop requires training, however members should not use any equipment without understanding its operational and safety requirements. Manuals and some video tutorials are available on the Machine Shop Committee page. If you require help with using equipment, send an email to [email protected]

Training for the HAAS VF-2 is is offered to members on a regular basis; see the event calendar for details. Once trained, members will be allowed to use the CNC mill only under supervision, until they have demonstrated their proficiency in its operation.

Training is not required for the use of the Bridgeport Mill, but a basic course in the operation of the mill is regularly offered. This class is broken into two sections, and in classroom session that covers controls, safety, etc. and a second session with some hands on demonstration.

It's important to note that these are things that should happen to the HAAS to make sure we keep it serviceable. The first section here are steps that need to be done with every use. If you find that this has not been done when you go to use the HAAS please let someone know by sending an e-mail to

So we can get with the last user and ensure they are aware of these needed steps.
