Is Yasnac correct for the post processor?

Just picked up a MV Jr, have not hooked it up yet and had some questions that are killing me to find out.
Info
Model SV-50/40
SN 388
Control MSC-518MC
inspection Date 10-24-96
Questions:
Will this run a rigid tap?
Is that what the G84 is?
Does someone have an example if it will do tapping?
I see graphs that show 4000, 6000 and I think 10000 rpm, where the different top speeds options? Or is there gearing or something that lets you change it? Sorry this is more of a hopeful question.
Has anyone hooked these up to a serial port and if so would you mind hinting on the pinout of the port or pointing me to a page in the manuals that will tell me. Also what is the port set up numbers, baud, etc. Again page would be good this manual is the best.
Here is the newbie question, who makes the controller for post processor sake?
Oh, anything I need to know about my new machine?
Thanks
Andy

NO WAY THATS A JR !!! thats an early SV50 high speed 30HP 10K rpm machine. Yes, rigid tap was standard.
Control is a Fanuc 18MC, standard Fanuc pin-out on the cable, std parameter settings. Do a search, i don't have them here but it's been asked 100 times on this site.
Watch out if the machine has been stored for a while. Thats a pretty fast ATC arm on that thing and the tool lock plungers may be stuck on the arm. If they are, it will throw a tool VERY HARD.
Mori NEVER used a Yasnac on an SV machine. Think they stopped all Yasnac stuff in 95.
Some basics For the MSC-518 on a SV-50
sample code
Notes:Code:N## G0 G43 G54 G90 X##.#### Y##.#### Z2. H## Z.5 T## M8(GO TO YOUR INITIAL PLANE, CALL NEXT TOOL, FLOOD ON) M29 S#### (SET SYNC MODE AND SPINDLE SPEED) G84 Z-1. R.2 Q.4 F###.#### (FEED IS IN IPM UNITS) (Q IS FOR PECK TAPPING) G0 Z.5 M9 (RAPID RETURN TO INITIAL PLANE, FLOOD OFF) (G0 CANCELS FIXED CYCLE LIKE G80) Z2. G28 G91 Z0 M1 (TAKE SPINDLE HOME FOR TOOLCHANGE) M6 (TOOLCHANGE)
Don't use an M3 - spindle should be off when an M29 S#### is given.
G84 - the Q value is optional and usually omitted (tap full depth in single pass)
No Z axis movement is allowed after the M29 is issued other than the actual G84 cycle.
G80 or G0 will cancel the M29
Good luck, The SV50 is a great toy!
You maybe right, I looked at the tag earlier today and it was made in 86 I think; so I think some of the paper work I received with is for a different machine. I need to look into this. I will let you know more about the machine tomorrow, when I get back to the machine. Thanks for the warning on the tool changer, since I am new to tool changer would you recommend a process to see if it is working ok. I have two sources for the status of the tc, when I bought it I was told it was not working, that's why the price was cheap, when I talked to an operator he said it was working but was real noisy. I have not hooked up power yet so I have not been able to play with it.Originally Posted by underthetire

86 would for sure NOT be an SV, nor a MSC518 control. Is the machine green or white and blue?
it is green
Could be Yasnac or Fanuc then.
Models of green vintage (at least common ones)
MV-35/35
MV-35/40
MV40/40
MV45/40
MV45/45
MV50/40
MV50/50
MV65/50
And yes, MVjr in the later portion-late 80's. A Jr is basicaly a stripped down MV40. It may or may not have rigid tap then, as that was an option for most machines back then. An 86 could be a Yasnac MX1 or MX2, or Fanuc 6/10/11
I will make sure to look more tomorrow, would like to find all of this out, thanks for the help.

If you can get the sn off of the tag on the electrical cabinet door, I can see what control type it has (and maybe alot of other information). By the way, the tag wil tell you the model as well. Good luck.

You will have it tomorrow sir, thanks

I have an 86 MV-JR. Yasnac MX-2 control. How do I tell if it has rigid tapping? Command an M29?
