Getting rid of my rotary table and dividing head
Ignoramus8246
and the dividing head. The reason is that I came across something
similar to this:
It also is threaded on the OD, with 2 3/16-10 thread, so it accepts 5
inch Hardinge chucks.
This thing is programmable, so I can just say how much it would turn,
in degrees, and it would do just that upon pressing a button. I hope
that if I get the CNC mill to work, I can interface with this 5C head and
make it a fourth axis.

I wouldn't get rid of the RT or dividing head, there are things that
those will be better for, particularly irregularly shaped items that
need to be clamped to the RT T slots, not held in a chuck.

I do not really work on such things, or I can make some adapter
plate (backplate).

They are quite a good indexer. Now..there was an issue with those made
before 1999..a bad circuit board tended to flake out and of course Haas
charged to repair or swap..
Some of the earlier ones were made by other companies such as Yuasa and
rebadged for Haas, Fidal...etc etc
From what I understand Haas bought the rights to make the boards and
indexers in their own factory in the mid 2000s

Mine was made in 1987, and has survived up to now. They supposedly did
not use it much, which I think is true. I will try to be careful with
it, thanks for the heads up about the boards. The motor is a stepper.

There ain't no such thing. I think that he who dies with the most toys wins.
Seriously, that unit has value. Sell it. Keep your RT and dividing head. I
set up a small servo with timing pulley that will bolt right up to either
unit with just a belt and pulley on that unit. Then you got all sort of
capabiltiy for cheap. PC controls don't need the brain box that comes on the
HAAS unit.

Pete C.
Seconded. A chunk of the cost of the indexer is the sequencing
controller that allows it to interface with just a trigger output from
an older CNC controller to step it to the next position in it's
programmed sequence. Iggy can just put a real servo and drive on either
his RT or dividing head and control it from his new EMC2 control as a
full 4th axis, not just an indexer.
As for the "too many toys", that is just the justification to move to a
nice rural location with elbow room and a huge separate shop building.

But, guys, I could as well control the Haas 5C unit with EMC2, right?
It is just a stepper motor with an Amphenol plug?

Pete C.
No, it is a stepper motor connected to a combination drive and
sequencer. You could eliminate the drive and sequencer and put a new
stepper drive on it and then control it from EMC2. I'm not sure if EMC2
will support both steppers and servos in the same configuration though,
so you might need to replace everything with a new servo and servo
drive. As-is, it is an indexer only, and not a full 4th axis. You can
trigger it to the next step in the sequence with a GPO bit, but not
command a specific position, feed rate etc. like a full 4th axis.

Which is what I was trying to say, in a clumsy way. I would take the
drive completely out of the picture.

I understand, yes. I hope that EMC2 can control both servos (in the
Interact II) and steppers in the same setup.
Even if I fail at the Interact II conversion, completely, and just
part it out, this indexer would be super useful with the manual
Bridgeport.

How is the indexer more useful than a rotary table or dividing head on a
manual machine? A few cranks on the RT or DH does exactly the same thing
as a few button presses on the indexer.
Ignoramus9410
If the number of points that I need has no common denominator with the
number of holes in a circle on dividing head, multiplied by 40, I am
pretty screwed. Not so with the indexer.

Pete C.
They have multiple circles of holes and multiple plates for a reason. I
can't see any reasonable application the DH wouldn't work for, and the
RT is easily set to any degree just like the indexer.

If it fails..Ive got some people that can fix them moderately
reasonably, but expect to pay at least $500 for a repair. Shrug.
Well..that was before the bottom fell out of California
manufacturing..they may fix em cheaper now.
Yours may have been made by Yasua based on age.

Iggy, you don't use the hole plate on a DH when in CNC mode. You can move
any amount you want, even while the other axis are moving. You can even set
your DH at the helix angle and hob gears with a blank in the DH and a hob in
the spindle., both moving in coordinated motion. The RT is handy for a huge
part bolted to a face plate. Again, you can do any full 4rth axis work you
can dream up.
Now, this route is not for a high production shop. But you can make some
wonderfully complex parts with just these tools.

Karl, as it happens, I already sold both the dividing head as well as
the rotary table, though technically they are still at my place. In
any case, I have a chuck for this indexer, so I can hold decent sized
parts. I hope that ine day I could make a stepper control for it, and
will not deal with backlash, as on a rotary table.
If I ever need a rotary table, every third bankrupt mold shop has a
Troyke DMT-15, and with a bit of patience I can get one inexpensively
again.

That's good.
This one cost me $105, IIRC.
