Looking for manual/parts list for Haas? Rotary 4th axis. Model # unknown. 12" platter.

This 4th axis came with a Nasa Machine Tools vertical mill. Built around 1989. Nasa told me that it was supplied by Haas. That is all the information I was able to obtain. Nasa will not return my emails. I have not contacted Haas. Their contact form does not permit the attachment of photos. Their online archive of manuals does not go back that far. I would like to at least determine the model #.

It is heavily leaking oil, and needs fixed.

Thanks,

Bill

Does that say Haas anywhere on it? I have one of their earliest brochure packs here and the 12RTV was their model in that size back then. The castings look nothing like that one. That looks like it could possibly be a later one I don't happen to have brochures for but, the motor and the belt drive housing don't look quite right.

Haas was in a 10K foot building in Sun Valley back then. They didn't make much of anything. I'm pretty sure they bought manual rotary devices from the popular companies back then and then applied their rotary control box and motor. Does this even connect to a Haas rotary box on the machine? If not, being "Haas" may be academic at this point. They bought the motors and other bits from other companies, made some pieces to adapt them and create what you have there.

Can you post a picture of the remaining side (the belt drive cover)?
 
I have found no markings on the unit. It uses the same servo (SEM) and drive (SD-1525) as the rest of the mill. The servo installation would have been done by Nasa.

The platter center is an MT #4.

Mill has a Fagor 8020 control.

What were some of the other makers of rotaries back then? The only other one that I tried to look for was Yuasa.

Thanks,

Bill

Guessing it just uses O-ring seals. You can get O-ring cord from McMaster and make your own for the larger sizes.
Table most likely sourced from a manual.
My '91 VF-1 uses 14 pin connectors. Your rotary the same number of pins?

Split into two 9-pin connectors. 13 wires total.

Depending upon whether your encoder is TTL or push-pull, it would use 5 pins or 8 pins.
Motor uses three pins (two power, one ground) and if there is a temperature sensor another one or two (could have common ground with the motor). If a Home sensor (two power, one signal) another pin.
14 pin connector uses four pins for motor power.
 
Nothing about that says Haas to me. The encoder says Heidenhain? Yeah, that's someone else's.

If the leak is the problem, I would take it apart and address the seals, regardless of who made it. It's old. Parts may not be available. Or you may find exactly as @magno_grail said: it's just o-rings and common seals. You may also open it up and find manufacturer markings inside the castings or on other parts. It sounds like it needs to come apart anyway.

Thanks. Was hoping to have an idea of what I am going to see before working on it.
