Re: [CAD_CAM_EDM_DRO] Re: Bridgeport Series I verse Series II CNC Refit Candidates

Those are the manual machines (apart from the EZ trak which was a beast
on it's own). The CNCs are very different. The Series 1 CNC is based on
the manual machines with a special rigid ram, often using 30 series
quick change tooling. Drive is via a varispeed belt from a 3 phase motor.
The Series 2 CNC is an altogether bigger beast and AFAIK there isn't a
manual equivalent. They usually take ISO 40 tooling with a pneumatic
drawbar. If I remember correctly drive is toothed belt from a DC motor.
