Hi folks
I have finally taken the plunge and bought a Bridgeport mill.... well the Adcock built version of it actually J2B with the vari-speed head, the machine is 3 phase and I only have single phase here, so...it has one of the modern ad-on drives to the X-axis (110volt) and a coolant pump which I assume is 3 phase. It also has a modern Sino 3 axis DRO just fitted which I have asked to be supplied with a simple 13 amp plug fitted.
I can't see much of a reason to go down the rotary phase convertor route if I ignore the coolant pump and the X-axis motor, I'm just left with the main motor to worry about.
I have been told that the 2 speed Bridgy motors don't take kindly to being asked to run on inverters/converters, now, I assume that the motor fitted is 2 speed since it has the switch on the left side of the head?
Does anyone know if my info is correct, or has anyone on the "panel" gone down the inverter route for the main motor alone and can put me right?
I run my Myford 254 lathe on a Newton Tesla inverter set up and I would not hesitate to convert the Bridgy over to their stuff if the OEM motor won't be right on "pretend" 3 phase the only thing that worries me is the motor mounting, since it is flange mounted...is that unique to Bridgy's or can they be easily sourced in other brands? I have not asked Newton Tesla if they can supply a bolt on package for it yet.
I won't be fused if the Bridgy electrics become redundant provided I'm not missing something obvious here? It will perhaps be a bit ugly with all the different supplies coming on to it but since I have been quoted 800 notes for a rotary phase converter I'll learn to live with it and I don't want to have a another motor running noise wise if I can avoid it.
If I'm sounding a bit vague about the details it's because it ain't here yet I am working off pictures, it comes on Monday and the next challenge will to see if my Fergie 135's front loader will lift it off the guys trailer, should be fun and I'll take some pictures when we do it!
Cheers
