Can someone layout the progression of the Haas rotary tables for the last 10 years or so?

I keep seeing 7 and 8 inch Haas rotary tables on Ebay that nobody touches. But when a HRT 210 shows up folks go nuts. What gives? Are the older black (early to mid ninties) units inferior? What kind of index speed do they have?
I need some info men.

Don't know about early nineties, but I used a Haas from the mid eighties (their first effort, I believe). It was basically a Yuasa indexer with motor and control which could be activated with an M code. All the steps had to be punched into the Haas control (incremental moves only).

It wasn't extremely accurate or rigid, but that was understandable and predictable, given the price and nature of the hardware. The real bummer was the fact that coolant would get inside the unit and shut it down.

After a relatively brief tour of duty in the shop, the Haas went up on the shelf and stayed there.

ARB,

I don't know which "Black" units you are referring to as the extremely early units were black but quite different from the black units designated as HRT7, HRT9 , HRT11 and S5C.

The first rotary tables were adaptations of manual rotary tables and had a stepper motor "hanging" off the side of the table. This applies as well for the first 5c units.

The next generation of tables, (and 5c units too), had their servos enclosed in sealed covers. A cast unit for the 5c and a sheet metal one for the rotary tables. These were from about 1990 to 1994 or so. these are the HRT 7,9,11. And the S5C (5c indexer) would be from this time frame.


Nothing wrong with the HRT 7,9,11 series of equipment. Or S5C for that matter. Good servos and well designed enclosure. Good air brake and drive system. Very close to present day systems. And as you would expect the HRT7 was a 7" table. HRT9 a 9" and HRT11 a 11".

Just a note: there was also a H5C indexer that was a "stepper" motor driven indexer. Not to be confused with the HA5C which is the present day indexer with a servo drive.

Next came the HRT metric series.HRT160, HRT210,HRT310,HRT450 and HRT600. A HRT160 was 160mm table or 6.30 for imperial.

These units were red in color. And this series showed up in about 1995 until 2000.

In 2000 the units then started to be shipped as white in color. And are basically the same design as the red units.

This is just a very short and sweet explanation of the most common tables. As there are many more tables and indexers. Brushless, tilting, dual head, four head,ETC.

And there are 14 pin and 17 pin cables and on and on......

Oh and as far as speed..the HRT series, both 7,9,11 and Metric, all index between 60 and 80 degrees a second max. Depends on the size. That is for the standard models as they have high speed ones too.

Hope that helps some. If you need more or have specifics let me know and I'll try and help.

I also stand corrected on any of the above as my old mind has forgot a lot as of late.

WMS,

That is exactly what I was looking for. We have a 2001 HRT210 here at work. Nice unit as far as I can tell. Just wasn't sure about the HRT7 ,9,11 series.

I have a 1994 vintage machine that I am looking for a table for.

Thanks,

We tried to make an older HRT 9 work with our 2000 vintage VF0E, with no success.... Had lots of help from the local dealer regarding paramaters and settings, but just couldn't make it run.

I took it back to the company that had originally used it on their Haas VMC (early model with fiberglass enclosure VF-1?) , plugged it in, and it worked perfectly!

After a search, I found a (more expensive) used HRT210 which works perfectly on our machine.

For what it's worth, I'd suggest you try an HRT 9 with your 1994 machine.
