Just wanted to show my troubles in the world of CNC

[Malzra]

Well I've been busy lately so I finally get home and start on my CNC retrofit of a Bridgeport series II interact. This morning I was testing out to see if my Main spindle motor was working.

Powered everything up and a Faint "Hum" from the motor and no spin. Turns out I blew a fuse. Nothing big right? try again? same thing

I start to Ohm out the phases in the motor....and find out one of the three phases is shot. Wonderful... SO I knew what I had to do, OFF WITH IT'S HEAD

So I did and here's some pics of my adventures today.

So I'm sure I've done this wrong, I'm paraniod as hell about the speed control. The manual says I was supposed to turn on the spindle motor and run the RPM into the red then turn it off so the motor was proper position for motor removal. But my motor is inoperable so that was out of the question. SO if anyone has any nice words about how those go back together I'm all ears

I hope the motor rewind place is open tomarrow...........

MORE Pics!

I also have a Bridgeport Series II Interact 2. It is an awesome machine. You will be happy once you fix it. I had to throw out the control and retrofit.

[Malzra]

I know I used all your referance pics for digging into my machine. Also made a handy PDF printout of your photo manual (I bless you sir for posting it)

Your machine was in so much better condition than mine, I am jealous of it but i'm "Learning" so much.

Oh well At least by the end of all this I might know somthing about CNC equipment.

[ichudov]

Good to hear. I was photographing that manual like a spy, I had two minutes.

I would really like to get that PDF and post it on my website. Could you email it to ichudov@gmail.com, as a favor.

Thanks

does anyone know if you can do letter writing useing the machine control on a bridgeport xr760 heidenhain control because up to now i,ve been generating one on cad cam and sending to machine, i cant beleive these state of the art machines havent got the ability to do this and a crappy hurco can

[Malzra]

Haven't forgot about you ichudov I've seem to "misplaced" it lemme poke around abit more and I'll get it to you




Oh and while I'm here Just threw the motor into the shop, 500$ bucks for a standard rewind and bearings, 600$ if the bearings are "Special".....Oh Yay!


Well with any luck everything else will fricken work.

No the bearings are not special, they are over charging you for them, you can get, these motors on ebay for much less then your repair

Back again and I've got some new pictures of the reinstall of the (rebuilt) motor!

Turns out all it needed was "cleaning" the factory that this came out of did not care about containing the flood coolant and it was a nasty type of flood coolant at that so much so that the motor was half filled up with caked in old coolant.

So they did a good job making sure it worked like new and without further adew the pictures!
