Problem- Bridgeport VMC 500/16

[yarpo]

Hi,

I've got a VMC 500 in the shop. It doesn't do much, basically an accurate drill.....

I'm having problems with the toolchanger. It was working when we got it (2yrs ago) but now it doesn't want to play.

It goes to the toolchange position and either spins continously, resulting in an error message about orientation or gets past that and the carousel pops out and refuses to do anything else.

I suspect the encoder might be knackered.

Also, does this machine continuously use air?
Obviously it needs the air for the toolchange, but should it continually use air?
Or have I got a solenoid thats stuck open?

Cheers

What kind of drives and control?
Probably Fanuc drives. Two types of orient devices used. One was a encoder, and the other magnetic. Spindle probably has a piggy back orient board with adjustments on it. Make sure orient LED lights up. (check your manuals for how to adjust) Then the carousel should come forward. If it stops there, either the control does not see the verification switch that it is forward, or it sees it is forward, but the drawbar cylinder did not fire or in the process of getting on the tool it rotated the spindle out of orient.
